I finally ordered a pair of those shorts and gave them a try. My hammer drill worked about the same, but I was able to finish the job in a fraction of the time because my neighbors kept stopping by and offering to help. Nice guys!
A rotary hammer is basically a small jack hammer combined with a drill. The hammering is completely independent from the rotation, and it is quite powerful. A hammer drill is a drill with cams around the chuck to make it bounce and "hammer" the surface you are drilling when it rotates. The impacts are much less energetic than those from a rotary hammer.
Found this video while looking for a hammer drill. Finished the video, and ordered a Rotary Hammer Drill instead 😄I didn't even know this tool existed until about 5 minutes ago. Thanks mate! saved me buying the wrong thing.
For future reference to everyone on what the difference is. Impact drilling does not cut material as regular drilling does, all the front end of an impact drill does is bash into the material to dislodge a piece which then gets cleared out by the spiral. So the absolutely primary part of this process is impact force. Which is where a mere drill has problems as they only put a small toothed disk in there that generates small vibrations, where as the rotary drill has a huge chunk of metal getting smashed along the shaft. The drill might do something with soft/small particle masonry, but the moment you reach a harder piece it hasn't got the impact force to hammer out material.
2 different tools for 2 different purposes. If you want a 1/2 chuck with hammer capabilities but are not drilling through rock often a hammer drill is the way to go. If all you are doing is drilling rock then a rotary is what you want.
I was looking to buy a hammer drill but I am now convinced that a rotary hammer would be a better choice for me. Your demonstration made this very clear. Thank you!
Very very very useful video. I wish more content uploaders had more respect for their audience as you clearly do. No self-indulgent waffling. Just useful information. Thank you very much.
This video was simple, yet very useful. I'm doing some training for work, and I'm reading up on different hammer drills and rotary hammers. Seeing you use the two tools gave me a lot of insight, and will be able to help customers more now that I've seen a demonstration. Thanks a lot.
I desperately was trying to drill a 3" hole in a concrete wall with a Bosch hammer drill until I gave up and went to buy a basic Lidl rotary hammer. Best décision ever.
I once tried drilling a one inch hole in a dense concrete slab with my Dewalt hammer drill, and it took me over an hour if I recall. It took me forever to get about 1-2" deep. I finally gave up and went down to a 3/8" bit and FINALLY got through, and going back to the 1" bit took me another good while (seems like a bad idea, because doing that would eliminate the pointed tip of the bit from having it's penetrating action). I can't believe the drill didn't catch on fire before I was done (I quit about every 30-60 seconds to try to let it cool off, which made the job take much longer). It still works, but I use it for smaller jobs. And yeah - that one inch bit was PURPLE when I was done. Wish I had seen t his video before I bought that hammer drill... Live and learn.
Exactly what I needed to know--I'm going out first thing in the morning to add to my tools. The hammer drill took WAY TOO long to drill through some concrete tonight.
Hammer drill: A drill that has a small impact mechanism. Useful for drilling small holes in brick, cinder block and other softer materials. Rotary hammer: A demolition hammer with a rotating bit. Useful for drilling up to 2 inch holes in hard materials including concrete, granite e.t.c.
I finally calmed down after reading some "Larry Bird shorts" comments and the youtuber responding with saying his wife said he should be embarrassed for uploading this video. Some funny stuff and humor the up loader has.... With that aside, thank you very much for the comparison between the 2 types of concrete hole makers. I believe the rotary hammer is the way to go for my intended applications. Even in 2019, "vs" videos barely came out about 1 year ago. Thanks a bundle, sir.
Hammer Drill : light weight, compact, easy to transport to different jobs and use around the job site. Versatile - can be used for small - medium size holes (can bore large holes if you progress from smaller to medium to larger) through many different material surfaces with minimal risk to damage of home or property. Sds rotary drill : heavy, more durable, more powerful and robust - specializes in masonry/concrete drilling, good for boring large holes, over and over again. Usually used in construction work/heavy duty drilling where you need to drill multiple holes. Not versatile as far as doing more delicate or intricate, smaller holes on more fragile material.
I was asking myself the same question and researching online came across your comparison. Thank you for adding to the collective knowledge of the internet. Extremely eye opening, seeing the difference.
Great comparison! I bought a Hitachi SDS 8 years ago as a treat to myself, and it's still going strong (metal gearbox, not the cheapo one). Over the years I have lent it to various friends and family, and every single one of them ends up buying their own SDS shortly after. I honestly can't understand why there are still regular hammer drills available.
Rotary hammers like magic, when I got mine I tried the 25mm bit in concrete and it it just fell through it, I had to drill a few more holes to make sure it wasn't a bad bit of concrete but nope it is fearless with concrete also it will go through reo bar just have to take it easy so it doesn't deflect but it still chews through anyway. We tried drilling hundreds of holes through the edge of some concrete to fit reo bar for a joint with a makita hammer drill and after 2 holes decided
I would emphasize how clean the holes are. It makes a big difference in how secure the anchors are. Also SDS drills are available in much longer lengths which can be a big help for your back when drilling the floor.
Great informative video. I need to drill some holes in concrete so I can secure a post to an existing slab of 6" thick concrete. Very helpful, good video quality and narration
@bahathir Thanks much for your video response. My one regret regarding my video is that I was unable to hit the aggregate that plagued me while working on the actual basement walls. When I DID hit a piece of granite river rock in the foundation wall my progress was often literally stopped until I hammered and punched it with a long slender cold chisel. My video makes the two devices look nearly equal, when in reality the hammer drill is a door stop unless drilling cinder block. Excellent demo!
Nice video, I've used both of these tools and for drilling concrete, the "more hammer....less drilling" is the only way to go. As a millwright....there were days I installed 2-3 THOUsand concrete anchors...big warehouses with many Pallet Racks...Here in Calif...all Pallet racks must be anchored for seismic requirements...(earthquakes)....the high-speed 'drills' are also good at melting the silver solder and losing the tungsten-carbide tips....
You were probably working a 10 hour day. A bolt installed every 12 seconds is still smoking, no wonder you were melting bits. Did you switch drills off or just run em till they smoked?
@@windymeadowsoxteam7783 OK, I guess I should have checked my reply better....a hundred to 200 a day. one to two boxes of 100 anchors...3/8" and I drilled them to maybe 2-2 1/2". Big BOSCH SDS roto-hammer.
Wow that just settled my decision. I was looking at CPO Outlet's Malwaukee Heavy Duty hammer drill vs the 7A Rotary hammer for a bit more and was wondering how they match up when drilling concrete. Thanks a billion for the video!!!
Same experience. I bought a large corded Ryobi hammer drill and it sucked. Borrowed my electrician friends compact cordless rotary hammer and it drilled holes in concrete all day. The other couldn't do one
hi. i really appreciate this video. more importantly what did you use to cut out that slab of concrete? we are looking to cut a similar opening but 18" thick.
This video is a masterpiece 👏. Exactly the information that I was looking for. I am mounting a toilet and needed only to drill two holes in concrete. I have a hammer drill, but it will not drill the aggregate . I need the holses in a certain place to line up with holes in the toilet. . I previously rigged it because my hammer drill sucks. My rig lasted twenty years, but it is leaking now. I know I can drill my holes with a rotary hammer drill. Thanks for making this video. No one else has shared this information. Great job 👏
we had a company out installing a new heat and air unit, a few weeks later I couldn't find my Hilti. Couldn't say for sure that my drill left with them. I miss my old Hilti, it gets the job done. 😂
Excellent video. Bought a Craftsman 1/2 in. corded drill/hammer drill thinking that I could drill into my basement and garage concrete walls. Exactly as you showed, once into aggregate, it's not going anywhere! Going to get an SDS hammer drill.
Great video! I've spent many wasted hours with a hammer drill and concrete. Sprained my neck last time, too! Ordered a rotary hammer last night. Regular $1050 on clearance sale to $380. Cant wait to get it and save my back, neck, elbow, shoulder....
4:39... When you play off the wrist twister as if it didn't hurt at all to keep a manly reputation amongs other old school short short wearing craftsmen.
That's the same experience i had, the only probably with rotatory drills is that they do not give a clean hole, in other words, if you want to drill a hole all the way trough it will come out with a chunk of concrete...
Good Day! I hope you're enjoying a pleasant one. At about 1:20 where you advise about letting the machine have a good bounce. I used to restore vintage power tools, going back to the early 1900's, and some came with original instructions. More than once the Ol' Timey Instruction authors, while writing about how much pressure to use with the machine in question, power drills, saws, and such, advised to use just the right amount of pressure to let the tool do the work, and also warned not to "Crowd" the tool. I feel pretty certain you didn't pay a pile of money for your power tool so you can get a stiff muscle somewhere while trying to Force (Crowd) the machine, and not allow it to do the work for you. This video is my first introduction regarding the usefulness of the Rotary Hammer. I like it, and believe it to be an Excellent demonstration. Thank You for taking the time to create and post it. Enjoy! ~ john b.
Thanks for the video, i have a big old makita hammer drill and i just opened up a case i had in the garage of an aeg roto hammer and didnt know the diff. They aeg makes the big makita look not soo big. These were all my grandpas tools as he was a general contractor and has since passed but going through the garage i find all sorts of tools. My makita is same size as your dewalt and the aeg is huge like your roto
This is my second time coming to this video after a year, it was flawless last time with a hammer drill. This time I'm stuck with 3 holes against an aggregate using the same hammer drill and getting concerned with my hands getting tremors. Time to invest on a rotary hammer 💰
Hammer drills are good for smaller holes like for tap cons etc. If you are drilling holes larger than 1/2" or deep holes a rotary hammer is the way to go. The average homeowner should probably just stick with a hammer drill. I've drilled tens of thousands of holes with each.
Nope, buying a rotary hammer drill was the best investment I have ever made. My home was built out of concrete. There wasn't a single drywall. My hammer drill could not go drill through the walls without me exerting over 50kg of pressure.
That's why this guy isnt showing a realistic demonstration, by using an over sized bit. I've framed my entire basement treated boards to the concrete, with my Dewalt corded 10 amp hammer drill for my tap-cons and it went through the wood and concrete in 20 seconds each time like butter. This is a biased guy here. Look at the size of the damn bit. That's what makes this a shitty comparison. I think your next comparison should be between a boat and a truck, bc both are used for transportation but by different means. Same thing.
Thanks im trying to drill 4 =5/8 holesto mount a harbor freight metal bender and im pulling my hair out trying to drill into the concrete i have it mounted on wood now need to go into the concrete ?
Good video. Nice info and demonstration. Not applicable though for the average homeowner looking to install a railing on their front porch or the weekend warrior. They simply can't justify spending $400 on a tool to drill 8 holes when they can go to Harbor Freight and buy a hammer drill for $40 that will do the job (in much more time give you). Yes the pros NEED these higher end tools for everyday heavy abuse and speed required for their application but if you're on a budget you can't always afford these workhorses. It also doesn't hurt to drop $100 on a good bit either.
Exactly, and you can drill the same hole using "regular hammer drill" just takes longer, for home use hammer drill (corded!) is BEST tool ever. You can work on wood/plastic/concrete/mix paint/cement etc. etc. etc. ONE drill regular person will ever need for most of the jobs.
Yeah, If you only use it once in your life. Once you get a tool that others need they will pay you to drill them or rent your tool from you. It's a big picture.
Put this in slow motion and watch the chuck on the yellow drill first it's going in reverse as it struggles to drill, no wonder the other drill went through like butter as it was going the proper direction
There is a big difference between 1/2" SDS masonry bits and 1/2"round shank masonry bits. There's a bigger difference between a rotary hammer that weighs and costs 3-4x as much as a 1/2" hammer drill. A hammer drill introduces some vibration, a rotary hammer applies spring loaded impacts. A 1/2 hammer drill is a drill that can handle occasionally drilling through masonry. A rotary hammer is the electrical replacement for a stra chisel and a hammer.
Eleven years later (5.26.2023) and this video is still the most helpful one I have found on the subject!!! Thanks for posting it.
I finally ordered a pair of those shorts and gave them a try. My hammer drill worked about the same, but I was able to finish the job in a fraction of the time because my neighbors kept stopping by and offering to help. Nice guys!

I’m drilling into an inch thick blue stone capstone so I can run a wire to a lamp. Which is best for this job? The hammer or the rotary?
Rotary always especially through brick. Some are harder than rock no kidding!
I just bought a hammer drill, now I can see I really needed a rotary hammer.
One of the more straightforward and concise tool demos I've seen anywhere. Told me what I needed to know, thanx much!
11 years later and you probably got best straight forward explanation I watched online. Cheers
I was looking to buy a hammer drill but I am now convinced that a rotary hammer would be a better choice for me. Your demonstration made this very clear. Thank you!
Depends on what you are doing with it.
7 years later and now I’m being informed enough to realize I need the rotary hammer. Glad I didn’t open the box of the new hammer drill I just got.
This might be the best commercial for a rotary hammer I've seen.
But that is what rotary hammers are for, drilling into concrete.

drill a 1/4" pilot hole first. Then drill your !' hole. You may find it will cut your time down to 10-15minutes.
Counted the time for each:
30 seconds for hammer drill
12 seconds for rotary hammer
What you didn't count was the amount of force needed to push the hammer drill vs. the significantly smaller force needed for the rotary hammer drill.
@@edinfific2576 I'm about to hop in my time machine and let this fool know he should be measuring the FORCE as well!

Not every rotary hammer is meant for demolition. The smallest ones have 1.7 Joule of energy, a proper demolition hammer has 7.5 Joule and up.
Wow, wish I saw this yesterday before drilling those holes in my brick - my hammer drill took FOREVER on just a few holes. Thanks for sharing!
Did you have your bit all the way against the back of the chuck? If not the hammer won't tap the bit
You used hammer bit? Designed for hammering cant use regular bits meant for drilling wood and metals.

without any arguments, rotary hammer drill is the only way to go......
This is my uncle. He's like this in real life too.
If you clear the dust out occasionally as you drill, it won't bind and spin on you, and you won't have to pull so hard to get the bit out of the hole.

Nope, buying a rotary hammer drill was the best investment I have ever made. My home was built out of concrete. There wasn't a single drywall. My hammer drill could not go drill through the walls without me exerting over 50kg of pressure.
Thanks Tim Allen, I mean Tom Allen
That's why this guy isnt showing a realistic demonstration, by using an over sized bit. I've framed my entire basement treated boards to the concrete, with my Dewalt corded 10 amp hammer drill for my tap-cons and it went through the wood and concrete in 20 seconds each time like butter.
This is a biased guy here. Look at the size of the damn bit. That's what makes this a shitty comparison. I think your next comparison should be between a boat and a truck, bc both are used for transportation but by different means. Same thing.
Thanks im trying to drill 4 =5/8 holesto mount a harbor freight metal bender and im pulling my hair out trying to drill into the concrete i have it mounted on wood now need to go into the concrete ?
Good video. Nice info and demonstration. Not applicable though for the average homeowner looking to install a railing on their front porch or the weekend warrior. They simply can't justify spending $400 on a tool to drill 8 holes when they can go to Harbor Freight and buy a hammer drill for $40 that will do the job (in much more time give you). Yes the pros NEED these higher end tools for everyday heavy abuse and speed required for their application but if you're on a budget you can't always afford these workhorses. It also doesn't hurt to drop $100 on a good bit either.
Exactly, and you can drill the same hole using "regular hammer drill" just takes longer, for home use hammer drill (corded!) is BEST tool ever. You can work on wood/plastic/concrete/mix paint/cement etc. etc. etc. ONE drill regular person will ever need for most of the jobs.
Yeah, If you only use it once in your life. Once you get a tool that others need they will pay you to drill them or rent your tool from you. It's a big picture.
Put this in slow motion and watch the chuck on the yellow drill first it's going in reverse as it struggles to drill, no wonder the other drill went through like butter as it was going the proper direction
There is a big difference between 1/2" SDS masonry bits and 1/2"round shank masonry bits.
There's a bigger difference between a rotary hammer that weighs and costs 3-4x as much as a 1/2" hammer drill. A hammer drill introduces some vibration, a rotary hammer applies spring loaded impacts. A 1/2 hammer drill is a drill that can handle occasionally drilling through masonry. A rotary hammer is the electrical replacement for a stra chisel and a hammer.
how often are you supposed to clean the inside of hammer drills?
THANK YOU !!!!!! Your video just saved me $200.00, I will rent a REAL Hammer drill for $20.00 .........
