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 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.
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.
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.
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.
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!
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.
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.
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.
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.
Just remember that drilling holes on the ground, where gravity helps with the weight of the tool, is easier than drilling a wall or overhead up on the scaffold. Overall the rotary hammer wins, but it has a hefty weight.
You're right regarding the weight and gravity part, but belive me the difference between these are still evident. I live in a concrete flat where drilling a hole with a drill hammer takes minutes, and with a rotary hammer it is no more than 10-20 seconds. My device is 2.2 KG, so less than 5 pounds.
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 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.
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!!!
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
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
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
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.
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.
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
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.
Has anyone else noticed the the rotary hammer is 3 times the size of the hammer drill? Sheer physics would indicate that it would go through faster under its own weight with equal drill bits, pushing or not.
@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!
Great video! The aggregates is what always haunts me. I end up with useless holes that i have to fill, repaint and a lot of wasted effort and time. I need a rotary drill for sure.
Thank you for sharing. Good information. Also, I didn't know you could put a window in concrete like that, which I may do someday, now that I know it is possible.
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!
11 years later and you probably got best straight forward explanation I watched online. Cheers

Pair that with romper and were set

This might be the best commercial for a rotary hammer I've seen.
But that is what rotary hammers are for, drilling into concrete.
Clive Ellis Pretty much to to extend productivity
Lol
2:12 "One of the best holes I've drilled!!"...slogan of the decade.
You can also get chisel bits for rotary hammer for removing tile.
Bud you just saved me about 150 bucks and some serious headaches. I appreciate 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.
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.
Thank you for this tidbit of info. It really helps to understand which situation is best for either tool.
Thanks
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.
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.
Side by side reviews are the best. Good work

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!

drill a 1/4" pilot hole first. Then drill your !' hole. You may find it will cut your time down to 10-15minutes.
Great video, but those 80's Larry Bird / John Stockton booty shorts are killing me!! Lol
really tho...
hey man! it was 2011 when he did this; fashion was a whole different world back then :)
in 2011 i was 37 and was NOT wearing short shorts .. EVER ...
😂😂😂😂😂
he got a nice pair of legs - why bother?
Great legs man!! And the video was super helpful too!! Thanks!
Folks who come up with designs for these tools & engineers who find ways to build them to make our lives so much easier are awesome.
Great Job on the demonstration
oh this explained why it took me so much times to drill a hole, my hammer drill just doesn't work on concrete
Very good and informative demonstration. Thank you.
That was a very good comparison of the 2 drills. Thanks
The hammer drill is a multipurpose tool for smaller jobs.
The comparison is null

Thank you. I've been searching for this video for weeks.
Awesome! Exactly what I was looking for! Thank You!
Thanks a million!
Fantastic video. Thank you!
Using impact drill for concrete drilling is like trying to cut meat with a dull knife. Rotary hammer is a proper tool for concrete and stone drilling
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.

The struggles explained👍
Great video. Now deciding on the rotary hammer drill. What features are good (eg blows per minute, amps, etc)
I spent 2 hours drilling 4 little holes last weekend. Should have watched this 1st.
Thank you!
Thank you for the info! Really good
without any arguments, rotary hammer drill is the only way to go......
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.
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.
Really appreciated.

Sweet video! Does that rotary have a hammer only function? I am wondering how it fairs against an air hammer for chiseling.
Who likes short shorts?
I like short shorts!
Adjust the front handle to 90 degree to the trigger handle for a better hold... the way you have it is for transportation or storage.
This is my submachine hammer gun
I personally find hammer drills work best for 1/4 and smaller holes, especially with concrete screws.
Nice video. How many people helped getting that big concrete chunk up from your basement ?
Great comparison video for a layman like myself!
nice demo man a clear winner on this test was the milwaukee
He sounds a little like Beavis.
Thanks for the info and video! I'm wall mounting a massive tv and now I know I'm going with the rotary!! Thx brother
