Seesii is much lower in price atm when you click all the discounts: amzn.to/41xRxZt A Ryobi mid torque is also $99 atm amzn.to/4av6VJZ
TTC is on winter break next week. See you guys in the new year!
sisi is 130 usd now ... and 109 with discount... they are playing the change the price after the vide drops ..
Happy New Year!
Hey TTC, do you guys update your rankings as price changes?? I noticed the DCF921 is listed at $199 but we've been able to get it through Home Depot hack ($104) for a few months now..
I work at harbor freight and we just got in a 3/4 drive 1650 torque Hercules in
Why are they selling by the ounce
I am loving these Frankenstein/modified impacts. It's fun to see what is capable w/ parts already available or with what you are willing to make work together. Keep it up!
I'm sure MILWAUKEE is working on the new M18 COMPACT now with the same SETUP coming out next SUMMER
Ya I am surprised we haven't seen a separate bldc driver and going like 6s or much more like 10s
Dear Harbor Freight: _"If it's not broken, why fix it?"_
We all thought big brands would suffer because of HF. As it turns out, HF is suffering because of cheaper tools and fast online shipping. When the stores goal is to race to the bottom there’s always someone willing to go farther.
$....answer's always money
Probably just wasn't sustainable or profitable enough. Glad to have snagged one when they first launched.
Money.
I want to buy Hercules tools, because they are extremely good, with outstanding reliability and no electronics failures. But the Hercules $64 impact doesn't have a kit option, so you must buy a charger for $45 and a battery for $85. You end up spending $200. I wish Hercules would actually offer kit options on all their tools, instead of charging $45 for a little flimsy plastic battery charger? You can purchase a brand new Dewalt charger for $18 with free shipping right now, online.
Welp, looks like we need to slap a square anvil on the Hercules impact driver since HF dropped the ball here.
That's what I was thinking. But I'm curious do you really think the impact driver can do everything this can do? This channel had it maxing out around 200ft lbs. While tim at shop tools got 500 ft lbs out of it. Kinda confusing eh?
Woah, thank yall for putting HF to the test, I am very happy I picked up an old model while they are still on clearance now, saved some money and some regret. Keep up the good work ❤
Mine was free with the purchase of the 5amp battery and a charger. $99 total... hard to beat at that price imo.
Yesterday I bought a factory recon Ryobi PCL 250, 3/8" impact wrench for $25.06 including tax from my local Direct Tools Factory Outlet. They mainly sell Ryobi and Ridgid new, recons, and blems. My recon came with a one year warranty. But the store does not take returns for money, just exchanges, so I was a bit nervous. I was a little skeptical of this little unit even though I've seen positive videos and reviews. I bought this little lightweight tool primarily for lug nut removal. I had a stroke in 2020 that left my left hand kind of weak and gimpy so I was hoping this would help. It's supposed to develop 220 ft/lbs of torque. When I got home I took it out of its nondescript box which came only with the tool and a manual. Fine with me. I plugged in a battery. I have 2 batteries and chargers as I use the 18V platform for my string trimmer and blower. I tested the twister on my '06 Silverado lug nuts which I know where tightened to at least 100 lbs as I always check my lug nuts when I arrive home from my local tires shop. In fact I probably tweak them a little higher. The little tool zipped the lug nuts off with minimal hesitation, and I do mean minimal. It was almost instantaneous. Extremely pleased. This tool will accompany me and my family on trips. I know there are not Direct Tools stores everywhere but they do ship.
And to think, I was mad when I got a gen1 a week before the gen2s came out 😂
I’ve been waiting for them to test the Gen 2 before I decided which to buy, Gen 1 it is 😂
I was kinda disappointed since I have a gen1 in 3/8" once I heard about the new ones. Hopefully I don't need to replace it anytime soon because I don't want a gen2.
@@chrisjones6002i think i'm delusional but my 3/8 vs my 1/2 is pathetic i feel the 3/8 has 0 power but they're the same
@gang-yc4je my 3/8" isn't very strong but it does ok with a 5ah battery. It will take lug nuts off at least. I don't have the 1/2" version.
@@chrisjones6002 huh. my 1/2 with the 5 ah is perfect for car, some nuts are unbelievably tight so the 1/2 ultra comes out but mostly the little guy is perfect
Harbor Freight has an in-store deal right now for a free 5AH battery with the new torque only. Also the only Gen1 one in stock is 2hr drive from me VS 1 hour for the gen2. Might go with the Gen2 just for that lol
Man... This is what I had in mind for the Kobalt XTR I sent you guys last year. Impressive stuff.
"We all hate it, its awesome!" 🤣
Would love to see a video on some of the lower CFM pneumatic options (Like husky's 4cfm 800 ft-lb impact) which work a bit better than others with a smaller compressor
Mmmh pity you didn't add the normal M18, just to see how that curve would go.
as a makita owner, i am now really considering the compact seesii if i can get a bare tool, not a kit.
I have put together my "beans" last week, but used molicel P42As, looking forward to what it can do with the XWT17Z...
Such great content. We really need battery quality tests. Not power, but quality. There has to be a way to determine if Ryobi, Skill, Hercules, or SeeSii, batteries are any good? In the past I purchased new Ryobi tools, only to realize that their batteries appeared to function like used cells, with extremely high self discharge, and only a fraction of expected capacity. Surely the SeeSii has very low quality, or perhaps recycled cells in its packs? You guys have the ingenuity to devise some type of battery quality testing! It would be amazing to know if those cheap Skil tools have real batteries?
Would love to see the Worx Nitro and Nitro sub compact as a comparison for this list. Love your content!
For you to consider - how about monitoring battery voltage and current draw during tool runs? Maybe have an adapter made like you did for the battery pack but with coils, taps, gizmos inside to give you voltage and current. Besides a visual display, you could send these signals directly to your data program. If you wanted to get really fancy, you could tap the leads where they attach to the motor to measure internal loses of the switch, electronics and wiring.
Happy new year fellas.
Derek- what an animal! 😮 Job well done sir.
I have a Milwaukee M12 right angle that I converted to use a matco 16v battery, there are two (or one depending on the tool) things that throttle these tools, the current limiting resistor (higher voltage battery cheats this a little) and the temperature sensor in the tool, these two parts of the circuit board are what control the output going to the motor, the reason this test worked was because as mentioned it had more motor windings similar in effect to putting a M12 motor in an M18 (you are increasing voltage relative to the design of the motor winding and the circuitry only limits amperage not voltage)
Another way to picture it would be if you put a 6 volt light bulb in your 12 volt car, the 6 volt bulb will be BRIHTER then the 12 volt bulb, you wont blow the fuse in your car because the amperage is the same but obviously the bulb will overheat
I bought the Hercules for the good deal… it seems to be getting better the more I use it, I think they had way to much grease in it from production… takes lug nuts off way better after the 3rd battery charge
Harbor freight has updated the description on the gen 2 1/2" drive. It now says " delivers up to 325 ft. lbs. of max torque" instead of "500 ft. lbs. of breakaway torque".
Have you folks considered signing up for the off road games over at Matts Off Road Recovery? I think the TTC attitude towards detail and truth would be a great thing to see behind the wheel!
I love the scientific naming by the OP/view "Standard assy (reference)" lol
I would've appreciate you completing the testing with the Herc Gen 2. I install garage doors and I kill an impact driver every 6-9 months. That's the Milwaukee Gen 3 and Compact impact. The Gen 4 won't even last a month. I use an impact wrench to install doors as a result. I'm considering switching everything over to Hercules but I don't know if a Herc Gen 2 can keep up with a Milwaukee 2855-20.
The Frankenwaukee is giving you the “leave me the fuck alone” numbers
I RUN MY RYOBI with the 8 AMP 21700 BATTERY and it can smoke my M18 fuel 3/8 even my RIDGID SUBCOMPACT with 8 AMP EXP battery
If Milwaukee did that to their impact then they might have a hard time beating it in their next future lineups.
Loved the video on seesii wh450 comparison, seems to be the closest budgetwise to a m12 stubby. Absolutly agree on it feeling really nice in hand, best $80 spent on a whim a couple months ago LOL
They keep making the heads shorter, but the batteries bigger - I wonder if someone is going to turn the battery backwards so you can get the head into tighter places, and not be limited to the smaller M12 type battery form factor.
I’ve been waiting for you to do this new hercules compact gun, it couldn’t even take off a lug nut torqued to 80ft lbs, and on top of that it would shut off after a few seconds of impacting too.
I would like to see the Milwaukee vs the seesii wh500
I would love to see some festool tests
Maybe he could replace the hammer in the Milwaukee with some made of tungsten. That should increase its abilities even more.
And make it brittle, heavy, and breathtakingly expensive. (assuming you mean tungsten carbide)
Seems like swapping hammers occasionally shows gains, but the harmonic and resonance between rpm, torque, spring tension, and hammer to anvil interaction. Understanding those dynamics is the actual secret sauce lol
This just goes to show how much more powerful they could make these tools but they slowly release slightly more powerful year after year to keep selling them. Someone should do now what Milwaukee will eventually end up doing in another 3 or 4 years and that’s wrap that motor in as much copper as will possibly fit and see what they can do. You wonder why the gen 4 board said gen 3 it’s because it’s all the same just a couple tweaks maybe another round of copper or possibly slightly thicker wire put on the same one.
Nailed it, they are halting the progress, they could make the most optimized version right now and they certainly know how to do it. But in the end it is all about economics and marketing.
Awesome channel, thanks for the great content. Have you ever considered using a radio control car motor/lipo battery combo to make a Franken-torque beast? It looks like they could make massive power and torque figures 😁
Hell yea. I wonder at what RPM the impacts start to act like an ultrasonic engraver on your sockets hahah, probably 3000+?
Happy Holidays!
Should have slapped a 6.0 forge battery on the Frankenstein to see if maybe it would have blown up. I’m sure the owner would have been pissed. But we would have loved it, lol
Xtr kobalt 1/4 in driver, and swap on the 3/8th drive hammer assembly. It bolts on and has some big beans
Really like your videos man!!! Definitely glad I came across your channel!! I have a few m12 tools like the impact driver and the little wrench, I definitely want to get the m12 impact gun, I use my impact driver as one but it breaks the little socket adapters alot an I'm sure it's putting wear & tear on the motor lol
The problem with these test is there no daily use reported ..I do not believe that the Harbor Freight impact would survive daily use more than thirty days
You found a daily use review on this tool that's been out for a week?
It's like car and driver. Can't review a long term use 2024 model
Why use a Ryobi ? Anvil is farther out than the battery ? I have a Skill and for the price it's fantastic. Has a excellent halo led light that is the best I have used.
i'm puzzled with the new model, but who actually uses 3/8 impacts? i've just never seen a reason to purchase one over a 1/2", since my 1/2" sockets go down to 10mm. what's the point? the tool is the same size, around the same weight, often nearly the same price, and always weaker.. what's it even for? if i need to bust anything smaller than 10mm i'll just use my impact driver anyway.
When are you guys gonna do a vid on the new impact from snap on the ct9038?
It would be cool if they tested some Hilti tools
We've tested 3 so far but always more opportunities
Great video.
Can you test on the dyno makita xgt angle grinder ? I use ga023 (ga005 should have the same power ) with 180mm concrete cut disc and in my opinion its really powerfull. Would be nice to see it compared with most powerfull grinders.
That Makita xwt14z is way more expensive than 165 dollars bare tool,its currently 230.00...so I guess it stays where its at on the ranks...but,its nowhere near 8th place anymore.Others on the list are still the same price or waaaaay less like the DCF 921 on Amazon for 137.00...?..What...its a steal and at that price probably number 1 in cordless compacts..I understand why you cant just change the rankings...prices fluctuate..
Harbor Fake back at it again. Just stick to the formula and keep making monsters like that Ultra series. SeeSii always makes me smile.
But will these drive drywall screws? Do they have enough power?
I want to see you guys but a one horsepower motor (3 phase if possible) on a ryobi one+ HP
Why not build a monster compact driver and challenge viewers to make a better one and winner gets big price
Can you test panasonic powertools? They ar great imo
Hello! can i know bolt socket what size ?
Hey guys anyone know if you can 3/8 anvil swap the Hercules HCB81B 1/4in Brushless Impact driver???? It would be my literal favorite tool if that was possible!
We all know Seesii real name is cousin Eddy by now🤣🤣
Have you considered testing reconditioned tools? Direct tools outlet is a factory authorized refurbisher for TTI with stores scattered across the Midwest. Recently picked up a tool kit from them and was very happy. Would be interesting in seeing if these tools have a “previous life” actually affect performance
Hey ttc 👋 can you guys test the DCK scs hammer drill?
What if you cut the hammer and anval down to one Hammer inpact spot ya you would lose reliability but possibly let the moter build speed between each hit
In a timed test hitting half as often isn't going to do stellar tho
How long before some one machines a new anvil for one of these. Or changes the spring or what ever it is that let's it bounce.
They need an anvil more flywheel like for stability and less recoil effect! !!!
If u put the 12 Amp ryobi battery it would beat the best od them rtobi is milwauke u just have throw the same battery tech in it
I don't understand, the Hercules did better than the Ryobi and SeeSi but you DQed it
The Gen 1 sucked. My Dewalt Atomic 921B decimates it despite having more modest claims. Surprised to see this. I'm not sure what Harbor Freight is thinking here. This while I saw that they now have a 3/4 drive ultra torque...
That modded tool is awesome.
Bad HF
I used to like harbor freight power tools because although they were not very powerful, at least they were simple enough to work reliably. Now they're essentially just wish/temu bootleg power tools.
So an impact driver motor is better than an impact wrench motor??!!?? What?!!
how come Ridgid is not tested?
We've tested it. It's the best of the bunch imo ua-cam.com/video/gtEj2Sh9SK8/v-deo.html
If a company can’t come close to the leader of torque which is DeWalt, why not just shut down the operation.
Shame about hercules, I thought HF was aiming to be competitive. I recommend it for anyone broke starting out, but can’t if they go backwards with higher prices. Also ryobi, change the battery system already christ lol.
The Hercules tools are actually better than a "starting out"tool. They are expensive, they come with a long warranty that is just as good as other tool brands. So they are a professional level tool. The Bauer tools and then Chicago Electric, are their two "cheap" brands for people who have no experience. One mechanic on UA-cam, he did a 1 year review of his Hercules tools, batteries, and chargers, and said that he never had a single failure, after using them for commercial duty in a shop on a daily basis. There is a professional woodworker on UA-cam who says that his Hercules sliding miter saw is actually better in every way than the most expensive flagship Dewalt, and he stopped using the Dewalt.
question for anyone: will the 3/8 drive remove calipers bolts?
or a 1/2 drive.
Hard to get my 1/2 drive impact Ridgid into the lower mounted bolts.
3/8" can, yes. Like a 3/8" M12 compact. But it's not a sure thing.
@@TorqueTestChannel awesome TY...!
value engineering strikes again
Rather just the m12 stubby
I wonder if a spring spacer could remedy the hammer skip, and what that would do for the max torque
Big brain
Thinking the same thing, or just replacing the srock spring with one that needs more heft might do the job.
When are you guys gonna do a vid on the new impact from snap on the ct9038?
My local Harbor Freight hasn't had the old Hercules model in stock for about 2 months and I got tired of waiting for it. I ordered the Ryobi from Amazon. Looks like the Ryobi was the better choice.
The old Herc was nothing to get excited over to begin with. But I guess it's pretty wild we're expecting something good from HF these days.
@@TorqueTestChannel Because for awhile HF WAS doing some good stuff. Seems they might be backtracking now to save a buck..
I've got the brushless new Gen Herc and it is fuggin tits. I have to run it in speed two for some applications because it's too torquey.
@@seymoarsalvage the irony.
@@DudeEggsI have the new 3/4 one along with the 1/2 one and the 3/4 Really does the job on Big NUTTS
Thanks Derick!!! That was awesome to see! Thanks again for sending it in!
I’ve been using the 3/8 SeeSii since June. It works for what I need. Getting bolts out after breaking loose, tightening 14mm cap screws before final torque, and breaking loose 50nm torqued bolts. I also have the green 1/2 inch SeeSii. It’s not bad for the price, but does lose to a co-workers Kobalt 1/2 inch.
My use case is pulling apart, assembly, and setting up injection molding tools. The 1/2 inch works well for breaking bolts loose up to 240 ft/lbs, but struggles if someone used an air impact and over tightened. The 3/8 inch works great for 10mm and smaller bolts or as a get it started before grabbing the torque wrench. Battery life seems to be very good. I’d be up for testing in a manufacturing environment if the need arises. I’ve been in skilled trades for over 28 years.
So that's what I was wondering: are the SeeSii batteries any good, in terms of their long term quality, their rated capacity, and their self discharge rate? Have you done any comparisons to see how many bolt operations you can do with a name brand tool with a new battery, compared to your SeeSii? In the recent Project Farm channel "Generic Battery" tests, he found that the cheap no-name generic batteries only had about 50 to 70% of their advertised capacity, but OEM batteries were about 95%. (I can't remember the exact numbers).
Nice swap! I still can't believe how little copper they use for these windings, they could fit almost double in there and get better power and efficiency. When will someone rewind one of these buggers 😅
Don't think that will have any big changes, the core is probably already saturated. But it would be good to see any changes :D
@@Damicske you would still get much lower resistance, it is very common thing to tune on small ev bike motors and you always see gains (can run them at much higher cont power) and that is how oem ev car motors are setup, with highest possible infill
@@jonWilk8156 I mean not so much on per tool basis, but would probably add up for the whole production
@@riba2233 You cannot just add another wire or change to a thicker gauge one and call it quits! Especially in today's tools the circuitry and motor are closely interlinked with each other in terms of electrical characteristics! Said modification would only be safe if the Output driver stage is changed, to match your new Induction and Impedance values! In other words, you are just waiting for the Motor driver circuit to burn up. And that's usually the most expensive part of a drill...
@@Elektrotechniker sure you can. we are talking about BLDC control here, not BLAC or sine wave which need tuned values like you said. also you are not changing inductance or anything like that, just internal resistance which doesn't mean much for controller output stage.
Love the hellspawn - really respect the effort you put into all of your content, I know that’s a ton of work!
Hey thanks man!
O boy, I'd love to see how the ryobi 12 Ah stacks up against the 4 Ah and the old 9 Ah on more tools. Almost 20% gains on this tool translating over to their high torque or 4.5" angle grinder could make getting one of those big boys a worthwhile purchase if you already have the tools.
I wonder if you made a spacer to put behind the spring to increase spring pressure, if that would fix the issue of the increased RPM causing the anvils to skip. It looks like the anvil size is probably tapped out on this one, but it might make it get to max torque quicker, if every revolution was a hit. Also, might make it a little more consistent and less of a handful.
I mean, if going that far maybe try Mallory metal slug somehow? Like when crank balancing. That would allow you to add mass to the hammer without adding size 🤷♂️
I would love to see a review on the new Hercules 3/4" Impact Wrench!
Ryobi brushless tools tend to perform better with higher battery packs iv notice it with most of my tools even my vacuum 🤨 great market strategy tbh
2953 motor appears to be wound with two wires in parallel. This is often done as a single large strand of wire of equivalent resistance is exponentially harder to wind with. This likely means fewer turns per arm of the stator and likely results in a higher rpm/volt and lower internal resistance. The downside to higher rpm/volt is typically a less efficient motor but higher power density.
That said, I know these things as I used to rewind brushless motors for r/c aircraft. I had not really considered rewinding a power tool motor. Looking at the messy factory windings, I'd bet some gains could be made with a hand wound motor.
Have you thought about testing rotsry tools like Dremels before? A bit outside your wheelhouse, possibly, but I thought about this while browsing Home Depot and Amazon for one. There's plenty of examples on Amazon or Wish and some testing might do some good to see how well they can avoid getting bogged down during polishing or cutting.
Glad to see a Ryobi back on the dyno. Nobody regrets those deep discounts when they come around.
That seesii looks like an m12 stubby with an m18. You listening Milwaukee?
I want to love my Ryobi tools.... But everything is so frickin' underpowered! Yeah, I'm definitely switching battery platforms. Just having a hard time finding an alternative.
Thank you guys for your unending dedication of bringing us quantitative numbers!
That compact is my favourite and i have many others
it fits the best in the hand, the lights are better than others
i must say, using a 2 or 3 amp smaller battery is a must for feel
it’s just a quality piece
Thanks for testing the Seesii. I'd been looking at the Milwaukee 3/8" M12 for awhile since I have other M12 tools, but couldn't find a price I could stomach for a bare tool. I saw another review of sorts on the Seesii, and bought it during the Black Friday sales for cheap. I've been pretty impressed with its capabilities for the price, and it's nice to see that backed up with real world testing. The size is great, even if it is an 18-21v tool.
For that modded one you dont even need to buy the other tool, can just rewind it. Maybe even play around with different gauges of wire. The wire itself is cheap or even free if you take it out of an old drill in the trash pile.
I’ve got the cheap little Ryobi pistol grip inflator/hand burner if used for longer then a few seconds. It’s literally nothing more then a little brushed motor and a switch connected straight to the battery. Just for kicks, I took 3 fresh off the Charger Ryobi packs and ran them back to back just to listen to the fan speed. Very unscientific I know but the standard 4ah was clearly slower then the 4ah HP(the current model) which was clearly slower then the current 6ah hp. I was really shocked to hear what a difference it made in such a basic tool.
I would've called the Milwaukee Mod _"Hellboy"_ 😊 You know, due to being red _and_ having a giant rock hand that hits *really* hard! Of course, I'd be remiss to not mention he's also quite a handful almost all of the time... 😏
Anyways... End of the year, and just wanted to say how glad I am to have found you guys back when you were still under the radar! I don't have any need for the results you generate, but I do love the science! As well as the fact you are keeping manufactures in check.
So, again, thank you all for doing what you do. Your videos are not just informative, but *comical,* and we all need a laugh at the end of the day... ♥️🤘
_HERE'S TO 2024!_ 🍻 I look forward to even more, and even bigger, shenanigans by you guys! Hopefully that'll involve some similar home-brew frankenfreaks similar to _Hellspawn (Hellboy!)_ over there... Maybe some cross-brand swaps, or manually adding more windings??? 😈
Happy New Year 🎉 _(even if this _*_isn't_*_ your last vid of the year)_
Have BOTH RYOBI PSBIW25 and the HERCULES HCB84B2 and the RYOBI is way STRONGER
OMG!!! Derek contact me ! I NEED to do this ( crazy Milwaukee build ) for work!! And a little mad scientist-esque fun 😂😂.
Looking at various products, one can't help but think some are almost identical beneath the colored plastic. The phrase "probably made in the same factory" is (rightly or wrongly) used a lot in recent months and years. It would be interesting to know what you have learned about drills, drivers, impacts, and flashlights. For example, Milwaukee's parent company makes Hart tools, but I suspect they make others.
TTI designs and builds Milwaukee, Ridgid (cordless), Ryobi, Hart, AEG, Empire, Imperial Blades, Stiletto, Kango, Dirt Devil, Homelite, Hoover, Oreck, and Vax.
Its not really a secret, its on their website.
@@Chris-du7hiTTI doesn't "build" anything, facilities in China do.
@@Chris-du7hi Thanks, but I know that, it was the lesser known "brands" I am more curious about. For example, I see many tools that appear identical to HF. And Amazon is another with mysterious parentage. Also, some of the expensive "German" tools look a little suspicious. But never mind, I'll find out some other way.
The Gen1 Herc looks alot like the Bauer 1/2 compact brushless. If they are the same tool, I'm getting that BAUER! Before HF downgrades that one too...
The Bauer have a smaller motor. Otherwise the same
@@TorqueTestChannel I wonder how it comperes to this gen 2 Herc then. I have a ton of Bauer batts, so I been holding out on getting into the Herc line
@@seymoarsalvage Slightly under gen 2

Can you do a review on the new milwaukee 1/2 inche
It is the 2666-20
If you want pissed off anvil skipping attitude, just stick a 9 Ah FlexVolt on a DCF921. It'll be cheaper and leave the warranty intact.
