*READ 1st:* Appears as though this may be a "not a bug, it's a feature" deal? Overseas Hikoki advertises Power mode (P) as hitting 1.5 times a rotation, so this may be by design? We contacted HPT 5 days ago and they ultimately said they'd need to check with their Japanese engineers to speak to this. So I'm guessing it's not just new stuff to us. We tried to do our due diligence. Seems to be losing some that energy hitting the top of the next dog, but DOES sometimes skip it. Who woulda thunk. We don't see this advertised in the HPT manuals that came with these so you'll have to excuse us for that, we don't usually read international brand manuals before using a tool purchased here. What do you think? We could always take this video down if misleading.

I'm not sure how EVERYONE missed it. But this is actually advertised as a feature by Hi-Koki everywhere else in the world. They describe it as "Power Mode" (thus the P as the setting name). I remember seeing this somewhere on the US Site/Tool Packaging back when it was Hitachi and I'm not sure where it got lost. Or how every ToolTuber has somehow avoided the information. Now, that's not to comment on the actual result of their intention. Just that it definitely IS intentional. "When enabled under heavy load, the power mode dramatically increases the impact energy by reducing the impact rate to 1.5 impacts per rotation and extending the interval between successive impacts. This mode is ideal for long or thick screws." www.hikoki-powertools.com/products/powertools/li-ion-screw/wh18dbdl2/wh18dbdl2.html
@@HollinHoffman Good catch, obviously the gun still stinks however. I would not want a screw bending impact lol. This feels like a case of a feature that turned out to be a hindrance but HPT decided they are getting their research and development money back on that triple hammer feature results be damned
Looks like a case of “more is not better” it seems like just having two dogs is more ideal and gives the motor more time to build up momentum before it drops the hammer
yes but more blows per minute means that you can drive in a screw faster. TTC said this only occurs under the highest torque loads, so "more is not better" for these applications? meaning youre not driving the largest lags you can find but for medium torque applications im sure this design is optimal...everything in engineering is a tradeoff
I remember reading some marketing materials from HPT when this came out that said the impact hammers 3X when not fully loaded then 1.5X when fully loaded. Believe what you are seeing is by design. In real life screw installing I’ve seen no difference between the 18V and 36V. Just buy 18’s so when they break I’m out less cash. This is certainly not a lug nut remover, but does well driving screws extremely fast, especially 3” and below. It does run long lags just fine but gets way hotter than other impacts I’ve used. The impact mechanism will just about burn your hand if you run long lags non stop for 5-10 minutes. Thanks for cutting it open, I have always wondered how it worked!
Really cool to see it in slow mo. Have you ever used one of those really cheap 12v cigarette lighter plug impact guns? They spin up for a good 5 to 10 seconds and then whack. They actually hit pretty decent because they spend so much time ramping up to full speed.
@@TorqueTestChannel yes, please! I still have one of these in the wife's van, I don't have to worry about keeping a battery charged to run it when on the road. :) I may still have one to donate if you need.
Honestly, if such a tool were to draw from car’s 12v, the tool can have an internal step-up transformer and actually run at 18~24v easily. The question is going to be the amp draw on the outlet. It *shouldn’t* blow the fuse… 😅
You are along with the Godfather (Project Farm) providing a HUGE helpful service to hundreds of thousands (most likely soon millions) of tool users. You also instruct & educate during the process. I hope this platform is paying you what you are worth. (Probably not)
I like TTC better. Much more in depth info. I mean look at this video for example. Not just so much a A. Vs B. Vs. C. Vs D. Vs E. Which is cool too.. because like a lot us on this channel, I also watch PF. Just personal preference I suppose. Both definitely good stuff tho!
This isn't usually the kind of content I get on youtube, but I use the big 1/4" to 1/2" drive ones for work, and this is great. All I really know about them is that the pneumatic ones we've gotten just can't break the nuts like the Milwaukee ones do. Even if the pneumatic ones are supposed to have the same or more torque (and are fully supplied according to their own specs.)
Upgraded from an older 18v kit. ua-cam.com/users/postUgkxW1vOBRCMrgTCDEijzpVzDWsgI-Jm2iQv I independently chose the drill and impact tool, before I came across the kit.I like the 3 speed impact gun. It seems more powerful than my older one, and it can be set to be really gentle. The drill is more appropriately sized for my use. I used to have a hammer drill, but I did not like that it was so big and it was not a great hammer drill. I rather have a smaller drill like this, and then get a corded hammer drill for the odd case I need that.
Even if they call this an intentional "feature", it clearly doesn't work to accomplish what they say it does with the middling results these drivers get on your dyno. There's no heavier load than hammering on a stationary bolt, and the torque they make is nothing impressive. I smell a situation where the engineers had an idea, built it, and even though the results weren't that great they handed it over to the marketing folks to put a positive spin on it and sell it anyway. Still makes this video a valuable contribution, since it highlights the fact that even though marketing may sometimes be "true" in terms of features, that doesn't necessarily translate to "better".
I have the 36 volt Hitachi Triple and the sub compact impact driver and they feel great in the hand and the triple hammer is great, so much smoother at driving regular fasteners. I am a Makita guy but the new 36 volt battery is big but last sooo freaking long. You can build decks for days.
Believe it or not, "hammering a stationary bolt" is not something people normally do as part of their job. :-P Skipping one of the hammers at high speed means you get 33% less IPM but (up to) 50% stronger impacts, which can be beneficial in some situations. And worse in others.
@@RFC-3514 It seems that the engineers created slippage on the hammers for a certain effect. Not everyone wants a fast and heavy vibration Milwaukee. I own it and it's weird and smooth and has strange modes. In them years it will be a cult classic basically.
Regardless of the post-filming discovery that this is actually a "feature" designed into the tool, still very interesting, and also independently confirms the marketing material's claims about the feature. Keep 'em coming!
@@narmale If you watch the video referenced, it only did that to the longest stainless steel screws on the market, only on the 36v, and only in P mode. It drove all other large screws and lag screw just fine. It was also a torture test on the gun.
No wonder I was getting warped screws. This explains a lot. I first thought that my screws were warping from heat. I will now only use the triple hammer on screws I don’t ever plan to reuse. This review has been more helpful that I can express. 👍
I'm having a dumb moment... (or maybe it's because I don't own one) _How_ does this explain the warping of screws? Or is it the half-trigger power doing it, from the hammer hitting 1:1 instead of 1.5:1? Thanks
@@DUKE_of_RAMBLE I’m thinking that the way that the hammer momentarily sits on top then slides into position mixed with the variable rpm’s within a ten second or so time frame, vibrates the metal in a fashion that changes the metal on a molecular level from an odd phenomenon in regards to vibrations.
@@DUKE_of_RAMBLE I think the warping happens at full speed, and the odd vibrations from the design is halfway liquefying the metal through science. Vibrations can liquify solids if at the correct frequency. It just so happens that these triple hammers are causing a frequency that is doing something close to that due to the design.
@@paedahe4975 Oh. If I had to guess, it's simply that the screws aren't as hard of metal, and were twisting from the torque. However, if you have another, different brand driver, that has equal (or more) torque, but *doesn't* cause the screws to twist on the same batch of screws, then you may be on to something! 🤔
@@paedahe4975 They'd be red hot if they were experiencing that. However, I think you're talking about "Liquifaction", which is much different. That's where, say an Earthquake, causes a building to sink into the terrain. Dry sand and a speaker can demonstrate that. There's no heat involved, but _does_ require the material be made up of a non-solid material, like sand is. Plenty of friction to make it "solid" under normal conditions, but insert that vibrational frequency and it acts like a liquid.
This was one of the best made and most informative videos I have ever seen on UA-cam! Thank you for going to the expense and trouble of making it. I can see where in larger air driven impacts three hammers might have an advantage, but clearly in smaller tools, the two anvil system seems to have an edge.
Great video! Would love to see more technical stuff like this in the future. Too many channels just do the surface level reviews, and skip the in depth technical looks at the internals, mechanism, design, materials, etc. I love the AvE BOLTR style content.
Wonderful content, as always! I'm admittedly a big Metabo HPT/Hikoki fan, as well as a fan of their Triple Hammer drivers. Seeing this, I really wonder if Hikoki realize that this "forward" movement is wasting power instead of adding. The "P" Mode for Power, is supposed to skip as I take it, in order to provide a larger, more signifcant strike providing...more power. And if it weren't for the wasted action of forward thrusting, I could see that happening. I do find it surprising that a Japanese domestic company has overlooked something like this, but of course anything is possible. This model is from the Hitachi days, towards the end. There's alot going on here lol. Perhaps Hikoki's biggest domestic competitor, Makita has figured this out with their new 40V DST Driver. It's very possible they may have uncovered something similar in breakdown and testing of competitor drivers. All very interesting to say the least! I have already tried the new Hikoki, and it's great. I will also be recieving one next week hopefully, from Metabo HPT ACTUAL, for testing, and review. I'll have to look into this "skipping" action bigtime now! Thanks guys! Hope the Kobalts made it safely! Video should certainly not be removed. Though I do agree with you in changing the Title from the original.
So this hammer has "valve float" like at red line in an ICE engine. I wonder if using 2 springs with different rates would help like done in high rpm engines. Could even be specked and done at home if wanted, just need another smaller spring inside the large spring
A heavier spring would help but reduce its out put power. Think of it like a Syncro in a gearbox. The more teeth on the syncro the slower the gear change and the higher force required for a change. A race gearbox with greatly reduced number of teeth engages faster.
@@banannaninja you know how a syncro works? The friction between the cones gets the gear started then it locks in gear once the teeth have lined up. Fast changing syncro boxes have fewer teeth on the syncros to enable a faster change but occasionaly they wont fully get the gears lined up and they will crunch.. Not all race gearboxes are dog boxes. Straight cut gears are for strength not speed and are not relevant in this argument.. Also a "dual clutch" gearbox is a marketing term it can often mean a gearbox that splits the input drive through separate gear trains so its in every gear all the time just waiting for it own clutch on each gear to go.. Often used on old cnc machines the dual clutch actually means a clutch on each gear and the clutch logic is handled externally.
@@banannaninja Thats the idea, but its useless in fine carpentry or joinery. 18v and higher impacts are unusably overpowered. 12 or 10.8v is the way to go.
I got the 5 piece Metabo set with two 5AH batteries at Lowes on sale from $350 to $103 last week. My tool repair man advised against them based on internal components but you can't turn down that price even if they die. I used the impact, drill, and skilsaw to put together one of those crazy $4,500 swingsets with so many parts it would test any good man's patience. Sank probably 500 1 1/2-3" screws, 75 5/16×3 1/2" lags, predrilled 1/8-3/8" holes, tightened dozens of 5/16-3/8" bolts, cut a few 4x4s and some 1x3s, and they were great tools with almost too much power for cedar, and the batteries ended the 10 hr day with 2 and 3 out of 4 bars left. After seeing this I just went outside and tested the 18v metabo with 5.0 battery against the m18 fuel with 5.0 battery and dewalt 887 with the power stack using 6" simpson structural screws. The metabo barely lost to the m18 and blew the 887 away. My 887 has some serious miles on it from 6-7 years of abuse and 2 times being left in the rain so that's not the best reference for its capabilities but anyway I did notice the skip on the triple hammer and it still felt damn smooth and sent the lag no problem. I'll post head to heads if anyone cares but this video was extremely in depth and informative so it would be somewhat redundant for me to do that unless people were interested in refrencing practical Carpentry applications.
@@johncoops6897 All brushless impact, hammerdrill, skilsaw, sawzall, light, 2 2.5/5.0 multivolt batteries, and a charger. Was on sale for a month from $350 to $206 but there wasn't any on the shelf and then I found one in a random aisle covered in other stuff and when I took it off it had a $103 price tag on it. I used my Lowes card which is 5% off every purchase so basically covers sales tax and I got the kit for $104.
Skipping a hit can allow more energy storage for the next hit,since the anvil takes more rotational speed thanks to its increased angular travel ,wich is what you ask for at full power. At reduced trigger demand,you increase hit per minute,but reduces inertia on the anvil,wich is enough to drive small bolts,screws etc... Just an idea,i'm not qualified.
In theory yeah but the hammer doesn't skip a hit, it hits the anvil vertically every third hit exerting axial force which in turn deforms the screw in the video. It's basically 2/3 impact driver and 1/3 hammer drill. Would also explain it's lower peak performance.
@michaelovitch You are correct. Skipping a tooth allows for higher speed of the hammer to be achieved. Higher angular speed translates in higher impact energy at a lower rate. Bending the screws might be caused by the higher energy impact
I also learned for every frame per second in camera equipment it costs about $1 per frame. 8000fps=$8000. But I am sure this kit will be used in many videos to come and provides us with unique insight. I love the TTC.
There is no direct connection between the number of frames per second and the cost of a camera, because different cameras have vastly different specifications (the main ones being sensitivity - i.e., how much light they need - and resolution). A camera that can do 5000 fps at 2k resolution is going to cost a lot more than one that can do 5000 fps at 240p.
Ya, or a machine testing torque is not what it is build for. This driver is smooth as butter and I own Makita and Milwaukee too. Imagine a car built for comfort and testing it on jumps. But I can tell no one here uses this beast.
Thank you for this! I own the 18v version and hawve always wondered why it sucks for taking of lug nuts compared to my dads old 12v makita impact driver. I knew it had something to do with the triple hammer, but didn't expect this.
More lugs means the hammer has less time ti build up momentum before it hits the dogs. It is the momentum that comes from speed that allows it to hit harder and do more work.
Like I said in a video a while back, that triple hammer seems to be restricting the tool. not enough time in between impacts to build enough momentum and it skips a lot because of that
It only skips at the highest power settings. And, by skipping, that gives it twice as long to speed up, which means stronger impacts. That can be beneficial in some (though not all) situations.
I have to wonder how well this would work on rusted or stripped fasteners. The forward impacts would serve to seat the bit and shock the rust bonding. Might be an unintentional bonus.
It is obvious that the intended use of the impact driver is based upon its use to application. The foot torque requirement was based on what it is mostly used for so that the life of the battery can extend its life.
great info TTC I have many 18v and 36v metabo hpt tools and ive never felt the 18v impact driver to not be enough for my needs, the 18v grinder and a few of the other 18v tools seem underpowered compared to the 36v line but I've never thought of needing a 36v impact driver, thanks to your dyno I now know it's not worth the minimal gains 👍
biiiig props on TTC for droppin the beans!!! now for the show down we been waiting for. take two equally rated impacts, one pneumatic and one cordless and see that slow mo difference
With 3 hammers rather than 2, you have 3/2 times more many chocs for the same speed, but the energy for 1 round is the same, so the energy per choc is 2/3 times the one with 2 hammers. So, the 3 hammers design allows more frequent hits but also lighters ones. This is an impact driver that is more gentle for the bits.
Yes make the impact 3-d animation video please. Fyi: I'd already subscribed before the final part because of the due diligence and the curious nature on display.
Love high speed videos. This confirms what I suspected could be happening with two lobe designs already. But we don't see this drop in performance much so I assume I am wrong this happens with the common two lobe design. Still seems to me though a one lobe design would allow twice the momentum buildup and ensure spring return more reliably. I assume greater bearing and shaft stress is why I have yet to see this. Anyone remember years back they had emergency impact drivers you plugged in to the 12v lighter outlet? It would build up for 20 seconds and then give a single super hard hit to break loose lugnuts. I would love to see a cut open view of that working and how that compares on your dyno. Appreciate your vids for sure!
Skipping a dog is for gaining inertia by spinning up the hammer. The torque spike can be seen in twisting those screws. Of course that means lower drive speed we can also observe. I do not know your dyno setup but it just might not pick up those spikes sufficient enough to be a useful comparison.
The dyno works on bolt tension. If a tool can tighten the bolt more it registers it. The gained inertia seems to be stalled by hitting the top of the next dog 1st
Metabo Might be worse on the torque reading but man after using them for a straight hour, they ran much cooler doing the same job when I used a new Bosch impactor with 8.0ah battery… the Bosch would burn your hand at the metal just by the chuck… and I had power loss/weird sounds with the Bosch when they got hot
This is a prime example of adding more power without thoroughly vetting the rest of the drivetrain. We see this in automotive applications all the time where are you at a whole bunch of power or beans to an engine and you know your transmission will physically stay together with that much power but your clutch is not designed to handle that much power or your torque converter is not capable of completely Translating that power into movement. Very very interesting really cool of you guys to post this stuff up
Menards has the 36v on sale for 80$ right now +shipping , you could grab that one just to make sure theres not a difference between the internals of both models , I just bought a second one last night
This isn't *just* this impact. You can hear the hammers in other impacts skipping hits like this when things are really tight...Just ask MCT... It happens quite often when he tests impacts. But it's nice to actually visualize it. Thank you for this video. VERY COOL!
Man, great work! I already had the old version of this (the standard 2 hammer) and I got this one as a part of a kit on clearance for $120 with a hammer drill (what I really wanted) and 2 new batteries + charger. I'll keep the power down on tight fasteners.
Hi, very interesting and educational, it’s always good to try and improve any tool, this triple hammer is not necessary, manufacturers should just keep the original design it works awesome, excellent demonstration ty,
I think the test is flawed, there should be more inertial force to the higher degree of rotation in the hammer. I surmise that the peak impact torque happens faster than whatever is measuring it can actually measure. Everything is a springe and with every impact there is a peak, enough to loosen a bolt, but its different than standing on a breaker bar because peak torque is all the time. I'd be interested in seeing if the loosen torque is the same, with a breaker bar and vice versa.
Pretty cool! The three hammer models probably don't wear out as fast, and might allow them to use cheaper materials. It doesn't give the parts enough time to move, though. Very helpful video.
It definitely sounds like the triple hammer harms the tool more than any marketing it might gain from it. That doesn’t seem like it would last very long throwing the collet forward doesn’t seem like it would be very good for it popping buts in and out multiple times a second.
Okay so on the back of that hammer assembly, I see two tabs for transferring power. I wonder if, especially when doing the inconsistent sorta-1.5 hits per rotation, the angular momentum isn't being transferred consistently from blow to blow. The motor is pushing in two directions, while the hammer is pushing in 3 but not even at a steady rate. You could see Tools & Stuff almost fighting with it at some points, it's obviously got some lateral movement. You can even see this on other tools to a degree but the 120 vs 180 might introduce more fluctuating harmonic vibrations.
After watchig you and project farm, I'm pretty sure my next tool purchase will be Milwaukee; all in all, they seem to be the best but still reasonably priced.
I have to imagine they found this flaw while trying to develop this tool but decided the marketing value of a triple hammer was more than that of a tool that actually preforms as it should. That is why you find the 1.5 value online. It also makes sense that this works on bigger guns because they can overcome the higher spring pressure with lower gear ratios and more speed. Overall I would really love to be a fly on the wall at big tool companies when a UA-cam channel keeps them honest.
It comes down to the impact energy not being absorbed by the fastest of but being reflected back into the tool. That leads to the hammer. Being compressed higher up against the spring and just getting out of resonance.
nope not Metabo, but Hitachi the branding is just a stupid clusterfuck since the gone away from Htachi branding Hikoki and Metabo HitachiPowerTools are the same and just the former Hitachi with a new name depending on market Metabo without any suffix is a different company with different tools in their lineup useing different batteries and designs but the clusterfuck doesn´t end there, Hitachi Koki bought Metabo before the nameing change but isn´t part of Hitachi itself anymore some us based investor is the owner of now Hitachi Power Tools now so so the japanese company bought a german company in the same field and belongs now to an us based investor and while both companies still compete in the same field with different designs it´s possible to buy a tool from the japanese company thats useing the name of the german company in for instance the us damn i hate this stupid rebranding
I have Metabo HPT' triple Hammers and their 2 dogs hammer drills These impact drivers are not meant to be used for large lag bolts their are used to drive deck screw and other fasteners in which the triple hammer far exceed the control of my Milwaukee and even my Makita's Torque tests aren't the best test for impact driver quality/function Impact wrenches r great for those test I love the triple hammer and so do almost everyone who has tried them
Exactly. 👊 I own the Fuel 2853 (power) and the HPT 36v (control/ergonomics), but my favorite for speed-control and ergonomics is the HPT sub-compact (WH18DDX). I use it every day, and by-far more than the others.
@@d.a.9937 Yep that's why I own so many different tools and colors cuz different tools work better for certain tasks I reach for the Triple hammer for most screws and smaller lags and metal roofing screws Control is most important to me and the Metabo HPT is faster or as fast in most of those applications to my Milwaukees-more torque isn't what I'm looking for when driving large lags-I choose a impact wrench and even a clutched Hammer Drill for those
Dude this video is brilliant! Of course, it’s Utterly devastating to metabo, someone is definitely going to get fired lol but that’s not your fault. I thank you for the sacrifices you made to create this video. I wish I had money to give you because I totally would give you some.
You can see the bit calet moving up and down when it mangles the first screw in the video. Just ever so slightly proving forward thrust on the screw as it’s driving. Looks like valve float from weak spring also.
Seems almost like it was purpose-built for light to medium duty work... On the plus side, they got the bam down! The whack and slap need more work, though. Good job, really an enjoyable episode! 🐺🐺
I have the 18 volt Hikoki(hitachi) version of this, absolutely love it, light fast and powerful, waterproof too which was nice as it got left in the rain once, it is the version before the triple hammer but still multispeed
I would also love to see a video showing animation of how these types of tools operate in slow motion, just to get a better undersranding of it, so if/when you guys do that video, I will watch it... Subscription added.
The designers didn't get the timing right on the RESONANCE frequency of the dogs hitting the hammer, (or vice versa?), during the higher speeds. Very interesting. The designers should look into how to improve this!
Keep the vid up, its good info. I think this may be a better feature for a 3/8 or 1/2 impact wrench than 1/4 driver. Since you cut into it anyways, it would be cool to modify the dogs and anvils to see if you can get more power from it. Like you mentioned a more powerful spring, test that. Then with the facotry spring grind off one of the dogs, test it, then test it with the more powerful spring. then grind off one on the anvil side, test it with the factoryspring, then test with the other spring, then grind off another dog or anvil side. I think this would make a great video. You know....for science haha
Easiest explanation is that being owned by the original "pump them and dump them" Private Equity firm (KKR) means cost cutting and hype are to sole focus of the company. Both Metabo and Hitachi used to be considerably higher quality. Look up "Texas Genco" the next time Tx freezes for clarification.
this was a fantastic video, very detailed, I want to see every power tool demo'd like this. I am in the market for a new cordless drill/driver, one with an adjustable torque setting like my Hitachi that I dropped. Besides the duct tape holding the battery in, the fact they don't hold a charge nearly as long as they did when new a few years ago I am ready for an upgrade from 18 volts. I loved how the Hitachi performed and will likely buy another but if there was a better one out there I might consider it. Looking forward to more of your vids.
i modified lidl 220v ac impact driver that had hammer with impact surfaces on 45 deg so there was less torque than specified, i cut of that tilted surface and made it vertical, and put washer beneath spring to make it stronger, now it has much more torque than before in both direction
I’d like to know what size impact is more effective on rotating assemblies. For example when removing the harmonic balancer not from a crank shaft is a 3/8 better because it sometimes has higher peak force or is half inch better because it has more low end grunt. I think you can accomplish this by attaching your torque test rig to a brake rotor with either brake pads or parking brake shoes and applying pressure via a normal hand brake lever or captive nut and bolt.
Every impact driver does it to an extent, the collet thing might just be an issue with the collet though. I know Milwaukee revised the 3rd gen fuels for that.
Thanks for the great video !! I think there might be some element or safety feature as well at play here, In the 80’s corded drills had a habit of twisting out of the operators hand which resulted in a fractured or sprained wrist not to mention the drill flying out of your hand further creating potential damage to the project or people standing or working close by. I have these as well as makita and dewalt. For the utmost in reliability Makita wins it hands down so far me. Love the color and design of the Metabo
I think it’s skipping blows to the anvil from the hammer to give the motor a chance to “speed up” so the hammer can hit the anvil at greater speed/power. So the difference with these is some sort of “timing” where “low power” hits every chance it can where “high power” will skip every other blow to the anvil from the hammer to give the motor a chance to speed up and smack the anvil faster and more (perceived) times.
Looks like the spring can't keep up with the speed of the hammer to reseat itself like you said, and possibly the hammer, only having 120° instead of 180° to travel between impacts, can't build up enough momentum for an effective strike.
Remember, if you ask, "Let us know if you want to see that.", you already know that we DO. This is my fav video yet. Really liking the high speed camera.
I think Metabo should be sending the Torque Test Channel a check from the R & D budget. You guys are going into a more organized AVE area. Thanks for the info.
The extra hammer leaves less time for the motor to ramp up after each hit therefore it’s going to hit softer, more hits per minute but softer hits. This tells me it will drive screws quicker but won’t drive big lags very well.
Interesting I have two of these impact drivers and the 36 and the 36 volt Gen 2 from Japan and I've driven long fasteners so it's interesting to see these results. Still a fan of the impact I do prefer it over my milwaukee just the ergonomics and impact feel
perhaps the angle on the surfaces of the anvil that hit the bogs is greater than needed. Perhaps some of that angle can be cancelled with compensatory angles grounded in the dogs surfaces that meet the anvil hits, or maybe that would ruin the dog because perhaps the thing is cheaply case hardened and has no depth.
*READ 1st:* Appears as though this may be a "not a bug, it's a feature" deal? Overseas Hikoki advertises Power mode (P) as hitting 1.5 times a rotation, so this may be by design?

We tried to do our due diligence. Seems to be losing some that energy hitting the top of the next dog, but DOES sometimes skip it. Who woulda thunk. We don't see this advertised in the HPT manuals that came with these so you'll have to excuse us for that, we don't usually read international brand manuals before using a tool purchased here. What do you think? We could always take this video down if misleading.

I'm not sure how EVERYONE missed it. But this is actually advertised as a feature by Hi-Koki everywhere else in the world. They describe it as "Power Mode" (thus the P as the setting name). I remember seeing this somewhere on the US Site/Tool Packaging back when it was Hitachi and I'm not sure where it got lost. Or how every ToolTuber has somehow avoided the information. Now, that's not to comment on the actual result of their intention. Just that it definitely IS intentional.
"When enabled under heavy load, the power mode dramatically increases the impact energy by reducing the impact rate to 1.5 impacts per rotation and extending the interval between successive impacts. This mode is ideal for long or thick screws."

@@HollinHoffman Thank you! Have you found any HPT literature that mentions this?
@@HollinHoffman Good catch, obviously the gun still stinks however. I would not want a screw bending impact lol. This feels like a case of a feature that turned out to be a hindrance but HPT decided they are getting their research and development money back on that triple hammer feature results be damned
I guess the next test is how well will drive nails and what's the biggest nail it can drive?
It sounds like this is a ”It’s not a bug it’s a feature.” kinda thing.
Looks like a case of “more is not better” it seems like just having two dogs is more ideal and gives the motor more time to build up momentum before it drops the hammer
yes but more blows per minute means that you can drive in a screw faster. TTC said this only occurs under the highest torque loads, so "more is not better" for these applications? meaning youre not driving the largest lags you can find but for medium torque applications im sure this design is optimal...everything in engineering is a tradeoff
@@MattB90 exactly. For every action there's an equal and opposite reaction.
@@MattB90 more hits if it doe not miss but they dont have as much oomff behind the hits as a ragular 2 hammer.
@@OGbqze bruh, you stole that from Einstein.
@@HellZReaper134 I didn't steal anything. I just commented something. What are you on about?
I remember reading some marketing materials from HPT when this came out that said the impact hammers 3X when not fully loaded then 1.5X when fully loaded. Believe what you are seeing is by design. In real life screw installing I’ve seen no difference between the 18V and 36V. Just buy 18’s so when they break I’m out less cash. This is certainly not a lug nut remover, but does well driving screws extremely fast, especially 3” and below. It does run long lags just fine but gets way hotter than other impacts I’ve used. The impact mechanism will just about burn your hand if you run long lags non stop for 5-10 minutes.
Thanks for cutting it open, I have always wondered how it worked!
Y'all are the next level!! Thanks for the lesson, doctor. Yes. Dr. TTS. Explaining even I can understand. Nice work, doctors.
Really cool to see it in slow mo. Have you ever used one of those really cheap 12v cigarette lighter plug impact guns? They spin up for a good 5 to 10 seconds and then whack. They actually hit pretty decent because they spend so much time ramping up to full speed.
We'll have to do one!
@@TorqueTestChannel yes, please! I still have one of these in the wife's van, I don't have to worry about keeping a battery charged to run it when on the road. :) I may still have one to donate if you need.
Honestly, if such a tool were to draw from car’s 12v, the tool can have an internal step-up transformer and actually run at 18~24v easily. The question is going to be the amp draw on the outlet.
It *shouldn’t* blow the fuse… 😅
@@reallifeengineer7214 What fuse? Oh, you mean that bent paperclip where the colorful little fuse used to be? 🤣
You are along with the Godfather (Project Farm) providing a HUGE helpful service to hundreds of thousands (most likely soon millions) of tool users. You also instruct & educate during the process. I hope this platform is paying you what you are worth. (Probably not)
The only problem is that they MUST do reruns because slimy brands will ruin good products after getting good reviews because they are that cheap.

I like TTC better. Much more in depth info. I mean look at this video for example.
Not just so much a A. Vs B. Vs. C. Vs D. Vs E.
Which is cool too.. because like a lot us on this channel, I also watch PF.
Just personal preference I suppose. Both definitely good stuff tho!
This isn't usually the kind of content I get on youtube, but I use the big 1/4" to 1/2" drive ones for work, and this is great. All I really know about them is that the pneumatic ones we've gotten just can't break the nuts like the Milwaukee ones do. Even if the pneumatic ones are supposed to have the same or more torque (and are fully supplied according to their own specs.)
Brother this is by far your best video yet. Props to you and thanks for the high speed camera purchase. You seriously saved me money and headache.
Upgraded from an older 18v kit. ua-cam.com/users/postUgkxW1vOBRCMrgTCDEijzpVzDWsgI-Jm2iQv I independently chose the drill and impact tool, before I came across the kit.I like the 3 speed impact gun. It seems more powerful than my older one, and it can be set to be really gentle. The drill is more appropriately sized for my use. I used to have a hammer drill, but I did not like that it was so big and it was not a great hammer drill. I rather have a smaller drill like this, and then get a corded hammer drill for the odd case I need that.
Even if they call this an intentional "feature", it clearly doesn't work to accomplish what they say it does with the middling results these drivers get on your dyno. There's no heavier load than hammering on a stationary bolt, and the torque they make is nothing impressive.
I smell a situation where the engineers had an idea, built it, and even though the results weren't that great they handed it over to the marketing folks to put a positive spin on it and sell it anyway. Still makes this video a valuable contribution, since it highlights the fact that even though marketing may sometimes be "true" in terms of features, that doesn't necessarily translate to "better".
also, they're ripping off their 36V customer base. the 36V should be a redesign , and weigh less than the 18V.
I have the 36 volt Hitachi Triple and the sub compact impact driver and they feel great in the hand and the triple hammer is great, so much smoother at driving regular fasteners. I am a Makita guy but the new 36 volt battery is big but last sooo freaking long. You can build decks for days.
When used for what’s it’s intended for it is an awesome driver. Ultimate torque tests on a giant bolt isn’t what we use them for.
Believe it or not, "hammering a stationary bolt" is not something people normally do as part of their job. :-P
Skipping one of the hammers at high speed means you get 33% less IPM but (up to) 50% stronger impacts, which can be beneficial in some situations. And worse in others.
@@RFC-3514 It seems that the engineers created slippage on the hammers for a certain effect. Not everyone wants a fast and heavy vibration Milwaukee. I own it and it's weird and smooth and has strange modes. In them years it will be a cult classic basically.
Regardless of the post-filming discovery that this is actually a "feature" designed into the tool, still very interesting, and also independently confirms the marketing material's claims about the feature. Keep 'em coming!
so the feature is the ability to warp the screws your driving?
Yeah just like a Ford Pinto. The explosion is a feature....Its a design FAILURE.
@@narmale If you watch the video referenced, it only did that to the longest stainless steel screws on the market, only on the 36v, and only in P mode. It drove all other large screws and lag screw just fine.
It was also a torture test on the gun.
No wonder I was getting warped screws. This explains a lot. I first thought that my screws were warping from heat. I will now only use the triple hammer on screws I don’t ever plan to reuse. This review has been more helpful that I can express. 👍
I'm having a dumb moment... (or maybe it's because I don't own one)
_How_ does this explain the warping of screws?
Or is it the half-trigger power doing it, from the hammer hitting 1:1 instead of 1.5:1?
Thanks
@@DUKE_of_RAMBLE I’m thinking that the way that the hammer momentarily sits on top then slides into position mixed with the variable rpm’s within a ten second or so time frame, vibrates the metal in a fashion that changes the metal on a molecular level from an odd phenomenon in regards to vibrations.
@@DUKE_of_RAMBLE I think the warping happens at full speed, and the odd vibrations from the design is halfway liquefying the metal through science. Vibrations can liquify solids if at the correct frequency. It just so happens that these triple hammers are causing a frequency that is doing something close to that due to the design.
@@paedahe4975 Oh. If I had to guess, it's simply that the screws aren't as hard of metal, and were twisting from the torque.
However, if you have another, different brand driver, that has equal (or more) torque, but *doesn't* cause the screws to twist on the same batch of screws, then you may be on to something! 🤔
@@paedahe4975 They'd be red hot if they were experiencing that.
However, I think you're talking about "Liquifaction", which is much different. That's where, say an Earthquake, causes a building to sink into the terrain. Dry sand and a speaker can demonstrate that. There's no heat involved, but _does_ require the material be made up of a non-solid material, like sand is. Plenty of friction to make it "solid" under normal conditions, but insert that vibrational frequency and it acts like a liquid.
This was one of the best made and most informative videos I have ever seen on UA-cam! Thank you for going to the expense and trouble of making it. I can see where in larger air driven impacts three hammers might have an advantage, but clearly in smaller tools, the two anvil system seems to have an edge.
The triple hammer drives 2-4" screws quite fast
Great video! Would love to see more technical stuff like this in the future. Too many channels just do the surface level reviews, and skip the in depth technical looks at the internals, mechanism, design, materials, etc. I love the AvE BOLTR style content.
Wonderful content, as always! I'm admittedly a big Metabo HPT/Hikoki fan, as well as a fan of their Triple Hammer drivers. Seeing this, I really wonder if Hikoki realize that this "forward" movement is wasting power instead of adding. The "P" Mode for Power, is supposed to skip as I take it, in order to provide a larger, more signifcant strike providing...more power. And if it weren't for the wasted action of forward thrusting, I could see that happening. I do find it surprising that a Japanese domestic company has overlooked something like this, but of course anything is possible. This model is from the Hitachi days, towards the end. There's alot going on here lol. Perhaps Hikoki's biggest domestic competitor, Makita has figured this out with their new 40V DST Driver. It's very possible they may have uncovered something similar in breakdown and testing of competitor drivers. All very interesting to say the least! I have already tried the new Hikoki, and it's great. I will also be recieving one next week hopefully, from Metabo HPT ACTUAL, for testing, and review. I'll have to look into this "skipping" action bigtime now! Thanks guys! Hope the Kobalts made it safely! Video should certainly not be removed. Though I do agree with you in changing the Title from the original.
I hope they figure it out but I still am a metabo fan and their equipment has never let me down and for the price I'm extremely happy.
So this hammer has "valve float" like at red line in an ICE engine. I wonder if using 2 springs with different rates would help like done in high rpm engines. Could even be specked and done at home if wanted, just need another smaller spring inside the large spring
A heavier spring would help but reduce its out put power. Think of it like a Syncro in a gearbox. The more teeth on the syncro the slower the gear change and the higher force required for a change. A race gearbox with greatly reduced number of teeth engages faster.
@@banannaninja you know how a syncro works? The friction between the cones gets the gear started then it locks in gear once the teeth have lined up. Fast changing syncro boxes have fewer teeth on the syncros to enable a faster change but occasionaly they wont fully get the gears lined up and they will crunch.. Not all race gearboxes are dog boxes. Straight cut gears are for strength not speed and are not relevant in this argument.. Also a "dual clutch" gearbox is a marketing term it can often mean a gearbox that splits the input drive through separate gear trains so its in every gear all the time just waiting for it own clutch on each gear to go.. Often used on old cnc machines the dual clutch actually means a clutch on each gear and the clutch logic is handled externally.
@@banannaninja cool stuff. I love cross-over tech like how a problem is solved in 1 application translated to another
@@banannaninja Strangely still worse than the Milwaukee 18v
@@banannaninja Thats the idea, but its useless in fine carpentry or joinery. 18v and higher impacts are unusably overpowered. 12 or 10.8v is the way to go.
I got the 5 piece Metabo set with two 5AH batteries at Lowes on sale from $350 to $103 last week. My tool repair man advised against them based on internal components but you can't turn down that price even if they die. I used the impact, drill, and skilsaw to put together one of those crazy $4,500 swingsets with so many parts it would test any good man's patience. Sank probably 500 1 1/2-3" screws, 75 5/16×3 1/2" lags, predrilled 1/8-3/8" holes, tightened dozens of 5/16-3/8" bolts, cut a few 4x4s and some 1x3s, and they were great tools with almost too much power for cedar, and the batteries ended the 10 hr day with 2 and 3 out of 4 bars left. After seeing this I just went outside and tested the 18v metabo with 5.0 battery against the m18 fuel with 5.0 battery and dewalt 887 with the power stack using 6" simpson structural screws. The metabo barely lost to the m18 and blew the 887 away. My 887 has some serious miles on it from 6-7 years of abuse and 2 times being left in the rain so that's not the best reference for its capabilities but anyway I did notice the skip on the triple hammer and it still felt damn smooth and sent the lag no problem. I'll post head to heads if anyone cares but this video was extremely in depth and informative so it would be somewhat redundant for me to do that unless people were interested in refrencing practical Carpentry applications.
@@johncoops6897 All brushless impact, hammerdrill, skilsaw, sawzall, light, 2 2.5/5.0 multivolt batteries, and a charger. Was on sale for a month from $350 to $206 but there wasn't any on the shelf and then I found one in a random aisle covered in other stuff and when I took it off it had a $103 price tag on it. I used my Lowes card which is 5% off every purchase so basically covers sales tax and I got the kit for $104.
Skipping a hit can allow more energy storage for the next hit,since the anvil takes more rotational speed thanks to its increased angular travel ,wich is what you ask for at full power.
At reduced trigger demand,you increase hit per minute,but reduces inertia on the anvil,wich is enough to drive small bolts,screws etc...
Just an idea,i'm not qualified.
In theory yeah but the hammer doesn't skip a hit, it hits the anvil vertically every third hit exerting axial force which in turn deforms the screw in the video.
It's basically 2/3 impact driver and 1/3 hammer drill.
Would also explain it's lower peak performance.
That's why it bends the screws.
@michaelovitch You are correct. Skipping a tooth allows for higher speed of the hammer to be achieved. Higher angular speed translates in higher impact energy at a lower rate. Bending the screws might be caused by the higher energy impact
Really love this style of video, it's one thing to say something sucks, it's another to actually figure out why
I also learned for every frame per second in camera equipment it costs about $1 per frame. 8000fps=$8000. But I am sure this kit will be used in many videos to come and provides us with unique insight. I love the TTC.
Whoah.
There is no direct connection between the number of frames per second and the cost of a camera, because different cameras have vastly different specifications (the main ones being sensitivity - i.e., how much light they need - and resolution). A camera that can do 5000 fps at 2k resolution is going to cost a lot more than one that can do 5000 fps at 240p.
untrue lol
Wow this video is so far the best explained and detailed I’ve seen, thank you for sharing, I love how the impacts work
I LOVE THIS CHANNEL! Thank you for all of the real world data!
I'm kinda surprised the Japanese company wouldn't have noticed or even tested this considering its rather new tech for that style impact
I was thinking the same thing. I guess pioneers of new tech have hiccups from time to time.
"New" tech that has been around for a while.
@@l00nybin "new tech for that style impact". Hard to be a smartass if you don't read the full comment before trying.
Ya, or a machine testing torque is not what it is build for. This driver is smooth as butter and I own Makita and Milwaukee too. Imagine a car built for comfort and testing it on jumps. But I can tell no one here uses this beast.
@@lifeisgoodskt there is some validity to the triple hammer making things smoother with less vibration, especially if it's missing every few impacts.
This explains what I have been seeing in many test reviews, well done and I hope Hikoki take care of this problem and credit you for this discovery...
With the high speed camera there’s going to be so much more testing and interesting truths to reveal
Thank you for this! I own the 18v version and hawve always wondered why it sucks for taking of lug nuts compared to my dads old 12v makita impact driver. I knew it had something to do with the triple hammer, but didn't expect this.
More lugs means the hammer has less time ti build up momentum before it hits the dogs. It is the momentum that comes from speed that allows it to hit harder and do more work.
Like I said in a video a while back, that triple hammer seems to be restricting the tool. not enough time in between impacts to build enough momentum and it skips a lot because of that
It only skips at the highest power settings. And, by skipping, that gives it twice as long to speed up, which means stronger impacts. That can be beneficial in some (though not all) situations.
I have to wonder how well this would work on rusted or stripped fasteners. The forward impacts would serve to seat the bit and shock the rust bonding. Might be an unintentional bonus.
Semi-destructive testing filmed in super-slo-mo? Yes! More please!
It is obvious that the intended use of the impact driver is based upon its use to application. The foot torque requirement was based on what it is mostly used for so that the life of the battery can extend its life.
great info TTC I have many 18v and 36v metabo hpt tools and ive never felt the 18v impact driver to not be enough for my needs, the 18v grinder and a few of the other 18v tools seem underpowered compared to the 36v line but I've never thought of needing a 36v impact driver, thanks to your dyno I now know it's not worth the minimal gains 👍
biiiig props on TTC for droppin the beans!!! now for the show down we been waiting for. take two equally rated impacts, one pneumatic and one cordless and see that slow mo difference
With 3 hammers rather than 2, you have 3/2 times more many chocs for the same speed, but the energy for 1 round is the same, so the energy per choc is 2/3 times the one with 2 hammers. So, the 3 hammers design allows more frequent hits but also lighters ones. This is an impact driver that is more gentle for the bits.
Yes make the impact 3-d animation video please. Fyi: I'd already subscribed before the final part because of the due diligence and the curious nature on display.
Love high speed videos. This confirms what I suspected could be happening with two lobe designs already. But we don't see this drop in performance much so I assume I am wrong this happens with the common two lobe design. Still seems to me though a one lobe design would allow twice the momentum buildup and ensure spring return more reliably. I assume greater bearing and shaft stress is why I have yet to see this. Anyone remember years back they had emergency impact drivers you plugged in to the 12v lighter outlet? It would build up for 20 seconds and then give a single super hard hit to break loose lugnuts. I would love to see a cut open view of that working and how that compares on your dyno. Appreciate your vids for sure!
I've seen plenty of rendered videos but this is pretty cool.
Skipping a dog is for gaining inertia by spinning up the hammer. The torque spike can be seen in twisting those screws. Of course that means lower drive speed we can also observe. I do not know your dyno setup but it just might not pick up those spikes sufficient enough to be a useful comparison.
The dyno works on bolt tension. If a tool can tighten the bolt more it registers it. The gained inertia seems to be stalled by hitting the top of the next dog 1st
I have not expected this! Crazy!
I'm eager to see a air impact wrench working!
Very impressive and convincing analysis, thank you!
Metabo Might be worse on the torque reading but man after using them for a straight hour, they ran much cooler doing the same job when I used a new Bosch impactor with 8.0ah battery… the Bosch would burn your hand at the metal just by the chuck… and I had power loss/weird sounds with the Bosch when they got hot
fine video! Never hoped to see it "at work", this was so cool. Thanks.
Really interesting to see, thanks for cutting it open and getting the high speed. I'd love to see more high speed footage.
This is a prime example of adding more power without thoroughly vetting the rest of the drivetrain. We see this in automotive applications all the time where are you at a whole bunch of power or beans to an engine and you know your transmission will physically stay together with that much power but your clutch is not designed to handle that much power or your torque converter is not capable of completely Translating that power into movement. Very very interesting really cool of you guys to post this stuff up
I think it’s intentionally designed to skip, as it builds momentum when hitting the next ‘dog?’ Which applies additional radial force at higher torque
Menards has the 36v on sale for 80$ right now +shipping , you could grab that one just to make sure theres not a difference between the internals of both models , I just bought a second one last night
Oh we already checked. Not impossible to take apart. We wanted to see it while running which means cutty cutty
@@TorqueTestChannel watching video now lol , idk it is one of my favorite impact drivers still , but my Milwaukees are still my top dogs

Congrats on the high-speed camera purchase. Can't wait to see more if it.
This isn't *just* this impact. You can hear the hammers in other impacts skipping hits like this when things are really tight...Just ask MCT... It happens quite often when he tests impacts. But it's nice to actually visualize it. Thank you for this video. VERY COOL!
Here's one where DeWalt skips: ua-cam.com/video/FVuYaO5MG8Y/v-deo.html
Man, great work!
I already had the old version of this (the standard 2 hammer) and I got this one as a part of a kit on clearance for $120 with a hammer drill (what I really wanted) and 2 new batteries + charger.
I'll keep the power down on tight fasteners.
Hi, very interesting and educational, it’s always good to try and improve any tool, this triple hammer is not necessary, manufacturers should just keep the original design it works awesome, excellent demonstration ty,
Amazing video. Thank you for taking it to the next level and beyond!!!
BEST Video yet! thanks for the information. too bad you can't drop in a 2 anvil setup in to see if it gets better than the M18
AvE did the same thing on his channel to a Makita impact driver and you can see the impacting isn't consistent at high speed.
Earned a Sub! I like the numbers and the cutout, thank you!
I think the test is flawed, there should be more inertial force to the higher degree of rotation in the hammer. I surmise that the peak impact torque happens faster than whatever is measuring it can actually measure. Everything is a springe and with every impact there is a peak, enough to loosen a bolt, but its different than standing on a breaker bar because peak torque is all the time. I'd be interested in seeing if the loosen torque is the same, with a breaker bar and vice versa.
Seeing how the internals worked was awesome!
Pretty cool! The three hammer models probably don't wear out as fast, and might allow them to use cheaper materials. It doesn't give the parts enough time to move, though. Very helpful video.
It definitely sounds like the triple hammer harms the tool more than any marketing it might gain from it. That doesn’t seem like it would last very long throwing the collet forward doesn’t seem like it would be very good for it popping buts in and out multiple times a second.
Another great video here. Thanks for the cool content. Love this channel!
I truly tip my hat to this video. This was so informative.
Definitely need more slo-mo footage! Maybe you could talk to the Slo-Mo guys on the Slo-Mo channel and get some advice from them?
Yes, I would like to see you take apart all those power tools. It would be great to compare all the brands .. : . ) 👍👌
Okay so on the back of that hammer assembly, I see two tabs for transferring power. I wonder if, especially when doing the inconsistent sorta-1.5 hits per rotation, the angular momentum isn't being transferred consistently from blow to blow. The motor is pushing in two directions, while the hammer is pushing in 3 but not even at a steady rate. You could see Tools & Stuff almost fighting with it at some points, it's obviously got some lateral movement. You can even see this on other tools to a degree but the 120 vs 180 might introduce more fluctuating harmonic vibrations.
After watchig you and project farm, I'm pretty sure my next tool purchase will be Milwaukee; all in all, they seem to be the best but still reasonably priced.
Cool video man, I really enjoy watching all your videos
I have to imagine they found this flaw while trying to develop this tool but decided the marketing value of a triple hammer was more than that of a tool that actually preforms as it should. That is why you find the 1.5 value online. It also makes sense that this works on bigger guns because they can overcome the higher spring pressure with lower gear ratios and more speed. Overall I would really love to be a fly on the wall at big tool companies when a UA-cam channel keeps them honest.
It comes down to the impact energy not being absorbed by the fastest of but being reflected back into the tool. That leads to the hammer. Being compressed higher up against the spring and just getting out of resonance.
Great investigation. I'm impressed as well as grateful.
Sounds like Metabo made 1/4 rotary hammer drill!
Knew I would eventually have a use for those 1/4" hex shank masonry bits!!
nope not Metabo, but Hitachi
the branding is just a stupid clusterfuck since the gone away from Htachi branding
Hikoki and Metabo HitachiPowerTools are the same and just the former Hitachi with a new name depending on market
Metabo without any suffix is a different company with different tools in their lineup useing different batteries and designs
but the clusterfuck doesn´t end there, Hitachi Koki bought Metabo before the nameing change but isn´t part of Hitachi itself anymore
some us based investor is the owner of now Hitachi Power Tools now
so so the japanese company bought a german company in the same field and belongs now to an us based investor and while both companies still compete in the same field with different designs it´s possible to buy a tool from the japanese company thats useing the name of the german company in for instance the us
damn i hate this stupid rebranding
I have Metabo HPT' triple Hammers and their 2 dogs hammer drills
These impact drivers are not meant to be used for large lag bolts their are used to drive deck screw and other fasteners in which the triple hammer far exceed the control of my Milwaukee and even my Makita's
Torque tests aren't the best test for impact driver quality/function
Impact wrenches r great for those test
I love the triple hammer and so do almost everyone who has tried them
Exactly. 👊 I own the Fuel 2853 (power) and the HPT 36v (control/ergonomics), but my favorite for speed-control and ergonomics is the HPT sub-compact (WH18DDX). I use it every day, and by-far more than the others.
@@d.a.9937 Yep that's why I own so many different tools and colors cuz different tools work better for certain tasks
I reach for the Triple hammer for most screws and smaller lags and metal roofing screws
Control is most important to me and the Metabo HPT is faster or as fast in most of those applications to my Milwaukees-more torque isn't what I'm looking for when driving large lags-I choose a impact wrench and even a clutched Hammer Drill for those
Dude this video is brilliant! Of course, it’s Utterly devastating to metabo, someone is definitely going to get fired lol but that’s not your fault. I thank you for the sacrifices you made to create this video. I wish I had money to give you because I totally would give you some.
You can see the bit calet moving up and down when it mangles the first screw in the video. Just ever so slightly proving forward thrust on the screw as it’s driving. Looks like valve float from weak spring also.
Seems almost like it was purpose-built for light to medium duty work...
On the plus side, they got the bam down! The whack and slap need more work, though.
Good job, really an enjoyable episode! 🐺🐺
It seems Metabo have a lot of explaining to do . . . great work keep it up !
I have the 18 volt Hikoki(hitachi) version of this, absolutely love it, light fast and powerful, waterproof too which was nice as it got left in the rain once, it is the version before the triple hammer but still multispeed
interesting video, was really surprised how it rated power wise in tests
I would also love to see a video showing animation of how these types of tools operate in slow motion, just to get a better undersranding of it, so if/when you guys do that video, I will watch it... Subscription added.
Other than this being a cool video. You blew my mind when you broke down the slow motion time.
The designers didn't get the timing right on the RESONANCE frequency of the dogs hitting the hammer, (or vice versa?), during the higher speeds. Very interesting. The designers should look into how to improve this!
I got the older Hitachi branded impact driver of this and I love it.
Keep the vid up, its good info. I think this may be a better feature for a 3/8 or 1/2 impact wrench than 1/4 driver. Since you cut into it anyways, it would be cool to modify the dogs and anvils to see if you can get more power from it. Like you mentioned a more powerful spring, test that. Then with the facotry spring grind off one of the dogs, test it, then test it with the more powerful spring. then grind off one on the anvil side, test it with the factoryspring, then test with the other spring, then grind off another dog or anvil side. I think this would make a great video. You know....for science haha
Easiest explanation is that being owned by the original "pump them and dump them" Private Equity firm (KKR) means cost cutting and hype are to sole focus of the company. Both Metabo and Hitachi used to be considerably higher quality. Look up "Texas Genco" the next time Tx freezes for clarification.
this was a fantastic video, very detailed, I want to see every power tool demo'd like this. I am in the market for a new cordless drill/driver, one with an adjustable torque setting like my Hitachi that I dropped. Besides the duct tape holding the battery in, the fact they don't hold a charge nearly as long as they did when new a few years ago I am ready for an upgrade from 18 volts. I loved how the Hitachi performed and will likely buy another but if there was a better one out there I might consider it. Looking forward to more of your vids.
i modified lidl 220v ac impact driver that had hammer with impact surfaces on 45 deg so there was less torque than specified, i cut of that tilted surface and made it vertical, and put washer beneath spring to make it stronger, now it has much more torque than before in both direction
I’d like to know what size impact is more effective on rotating assemblies. For example when removing the harmonic balancer not from a crank shaft is a 3/8 better because it sometimes has higher peak force or is half inch better because it has more low end grunt.
I think you can accomplish this by attaching your torque test rig to a brake rotor with either brake pads or parking brake shoes and applying pressure via a normal hand brake lever or captive nut and bolt.
John Coops why don’t you check out this video by TTC m.ua-cam.com/video/iqUCrwem2Lc/v-deo.html
My milwaukee fuel also skips a beat on certain fasteners. Too many ipm? The collet also drops bits. Actually kinda dangerous.
Every impact driver does it to an extent, the collet thing might just be an issue with the collet though. I know Milwaukee revised the 3rd gen fuels for that.
@@reaperreaper5098 - yep, gen 3 has been corrected from what I can see, but you can change it out your self on the older models.
Thanks for the great video !! I think there might be some element or safety feature as well at play here, In the 80’s corded drills had a habit of twisting out of the operators hand which resulted in a fractured or sprained wrist not to mention the drill flying out of your hand further creating potential damage to the project or people standing or working close by. I have these as well as makita and dewalt. For the utmost in reliability Makita wins it hands down so far me. Love the color and design of the Metabo
My old brushed hitachi impact seems to detroy bits (of any quality) before stopping driving screws.
I think it’s skipping blows to the anvil from the hammer to give the motor a chance to “speed up” so the hammer can hit the anvil at greater speed/power. So the difference with these is some sort of “timing” where “low power” hits every chance it can where “high power” will skip every other blow to the anvil from the hammer to give the motor a chance to speed up and smack the anvil faster and more (perceived) times.
Looks like the spring can't keep up with the speed of the hammer to reseat itself like you said, and possibly the hammer, only having 120° instead of 180° to travel between impacts, can't build up enough momentum for an effective strike.
Excellent. Informative. Yes on further in-depth testing.
Thanks
Remember, if you ask, "Let us know if you want to see that.", you already know that we DO. This is my fav video yet. Really liking the high speed camera.
I think Metabo should be sending the Torque Test Channel a check from the R & D budget. You guys are going into a more organized AVE area. Thanks for the info.
Wow. Metabo needs a serious redesign. How did the engineer’s not see this?
Could be poor tolerances. I assume they just design it and someone else makes it?
Yes, I do want to see more tools could open so I can see how they work....I understand that that is expensive, but it's still interesting!
That’s it! I don’t even want it anymore. Straight to the 🗑
Cut it up
The extra hammer leaves less time for the motor to ramp up after each hit therefore it’s going to hit softer, more hits per minute but softer hits. This tells me it will drive screws quicker but won’t drive big lags very well.
Interesting I have two of these impact drivers and the 36 and the 36 volt Gen 2 from Japan and I've driven long fasteners so it's interesting to see these results. Still a fan of the impact I do prefer it over my milwaukee just the ergonomics and impact feel
That and the IP56 rating. Run it in rain with no fear
Another great video. Next time you film at high speed video can you put a reference dot to visually see the rotations.
perhaps the angle on the surfaces of the anvil that hit the bogs is greater than needed. Perhaps some of that angle can be cancelled with compensatory angles grounded in the dogs surfaces that meet the anvil hits, or maybe that would ruin the dog because perhaps the thing is cheaply case hardened and has no depth.
