You know you're getting older when you get more excited about a new video about power tools coming out from the torque test channel Vs watching vids about building modded cars. And that's what I grew up on.

This footage is killer. It's been a pleasure watching you folks continue to evolve your channel. Thanks for doing this stuff.

As a central EU denizen I can tell you from experience that 1970's Soviet™ Reinforced Concrete is no joke, and while a 2 kW corded Makita will eat it all day every day, for home use there is... BOSCH Uneo, and yes it's the green line! Would really like for someone to dig into it as I can't fathom it has a mechanical hammer mechanism - my guess is some direct pneumatic shenanigans. And yes, for its size it does work quite well (doing fi. 6 mm by 40 mm depth the main problem past the 9th hole in a row is the tool overheating!). EDIT (2024-01-27): I stand corrected, the Uneo most likely has a mechanical hammer with that wobble bearing thing. Regardless of which exact "flavor" of Uneo one gets, as there seems to be at least half a dozen different models under that exact name. And yes they are all "pneumatic" in the sense of "air compression is a thing at that one particular point", pretty much like all electric ASG pistols are "pneumatic".

Cool beans, that's the best SDS video I've ever seen. I've had an SDS Plus drill for the better part of 10 years, never thought I'd use it much, bought it just to drill a hole to run airlines up from my basement to garage, but have done hundreds of holes since for anchoring decks, installing my lift, TONS of tapcons, and a few more holes through foundations since then...plus lent it out to a bunch of people too. Well worth having one!

Honestly, this is my favorite channel on You Tube, Great work

Really cool to see how an SDS hammer drill works. I've used them for years at work but never thought to tear one open to look at the guts

I'm in the EU, and once had to drill a hole through the 30cm (a foot!) of exterior wall of my oold home, near tge ceiling where it's concrete. I didn't want to buy other tools so I used my corded hammer drill, expecting it to ve a torture... And it was. I finally got through after 45 minutes and a dead drill. A few months later, my electrician had to drill a similar hole in a similar spot, but he had the M18 max. Yeah, I got an SDS drill after seeing him lol. Cheap corded one, still does the job well.

I recommend using a hammer drill for holes near the edge of a slab or panel; less risk of spalling. Rotohammer for everything else. Btw I have been using the M18 1" (it is their smallest Special Direct System Plus with a demo/hammer alone setting) in the video for 8 years and it has been performing pretty well, I'd recommend it. Slotted Drill Shank is a pretty good guess though.

Thank u TTC for forking out the dough for all these tools, cuttin a window for viewing, and most of all, for shelling out the ridiculous amount of funds for a high speed camera. ❤ You guys/gals are good to us!

Thanks for the lovely and very informational video. I've always wondered how SDS Drills worked - now I know :D Is there a particular reason you guys haven't chosen Bosch for this example, the 'creator' of the SDS standard? :) P.S.: All SDS Hammerdrills are measured in Joules in Europe. No matter if SDS plus, SDS max or SDS quick. :)

Last summer I had to drill some half inch holes through some concrete pavers. I put an sds style bit in my M12 drill with hammer functionality, and it took me about 10 minutes of constant running on the drill to cut one hole. This was with a 300lb guy (me) bearing straight down on the thing. The one hole took more than one battery. So I went to Harbor Freight and bought one of their cheap corded SDS drills. All the rest of the holes together took less than half the time of the first hole using the M12 drill. We'll worth the $60 or so to have in my garage for the rare time I need to be able to drill through concrete.

Loved the music in the slowmo. I kind of had a giggle with it.

Be intrigued to see how subcompact drills compare to others.

Awesome! This is what I've been wanting to see for a while! Hope you keep testing different SDS rotary hammers.

Amazing footage and insight. As a DIY'er trying to remove a very large granite boulder I've spent way more than I care to admit on SDS drills. Unfortunately, as good as some of the cordless versions are, they're still not as good as their corded counterparts in the SDS-Max range when you need to do the big stuff. They also overheat more quickly. If you have a serious job - don't go cheap on these or on your PPE - use an extractor with a HEPA filter and make sure you're wearing an appropriate mask.

You guys always make great videos. Thanks for putting in the time.

Incredible video Torque! Thanks for putting in all this effort just to give us this great educational content.

Really cool video. Love the channel and the stuff you guys do. Keep up the great work

What a great episode, I've always wondered how the SDS hammer action works.

yooo yalls channel actually is for people not in the trades Im so glad yall have come so far!

Very cool. I always love it when you cut open the tool so we can see how it actually works.

I love this channel, the educational stuff like this is super fun to watch & learn!

I've said it before,, the best friggin tool review/testing content on KZfaq period!!! Thanks so much for all your hard work. We love your channel!

Finally! FINALLY!!!! A video about these drill impactor ish things that answers all of my questions!!! Thank you so very very much! I’ve tried to figure these things out, looked at multiple diagrams and had it explained in words multiple times multiple different ways, but this is the first time it’s ever finally clicked for me. Thank you so very very much!!!!

Yes!!!! I‘m glad you measure impact force on hammer drills and especially the comparison to the ratchet hammer.

Slow motion footage is awesome 7:52 @Torque Test Channel

Finally, I asked and wanted a comparison list from you guys for a long time for sds drills. Would love to see some more tools from the other brands tested on the hammer rig. And don't forget to add it to the Google drive sheet!

Really cool to see how they work!! Thanks for all the effort in bringing this to us. I had an interesting real life situation a few months ago. I had to tapcon some 2xs to some ancient brick for the parapet wall steel siding and cap. Using my electric Bosch SDS the tapcons wouldn't hold at all. Same bit size my DeWalt 999 would work perfectly. Hearing plugs required 😛

amazing do more slow mo camera vids pls like the inside of a reciprocating saw i always wonder what it looked like in their

Nice video and explanation, thank you! I also amuses me to watch rotary hammers at work chipping away at whatever the business end is pointed at. Can't wait for SDS rankings (hope they are coming). My personal story is that I was trying to drill around 20 holes in reinforced concrete to hang kitchen cabinets. The regular 18V combi-drill wasn't cutting it. And it was getting real hot (due to how the hammer mechanism works). Pulled the trigger on a rotary hammer purchase. One of the best purchases of my life.

Great explanation!! Can’t wait to see your ranking of best SDS hammer drill brand

Great video I have the Ryobi 5/8 I wish it had the hammer only setting but it still does a fine job for my occasional need of a hammer drill, can't wait to see if/ how much the new battery platform helps the Ryobi tools ! Great video, as always

Going from a bog-standard hammer drill to SDS rotary is a revelation. Glad to see details on why! What a time to be a tool buyer.

Love watching your channel! Always great and very informative! I wish you would have included the Bosch in the test,I have one and love it!

Thanks. I drilled lots of concrete utility poles , both square and spun. In the early days , say late 80’s, the hiltI corded was a wrist breaker. I called it the rebar dance. Set on hammer only it would cut through rebar. Funnier still is we were old school enough to strap a generator to the bucket truck to operate it amongst energized circuits.

This was beautiful and informative. Damn guys, nice work.

Fantastic seeing this in a controlled environment! Thank you.

Another's awesome and educational video, thanks! Can't wait to see more sds tools tested :)

Rotary hammers are my go to for all concrete drilling. The only exception being if I need to do a couple of 3/16" holes for tapcons.

Back in the late 70s, the way we drill through block wall was a star chisel bit and a 5 pound sledge or a 10 pound sledge. Yes it was glorious thing to watch while on a ladder.😅

4:47 Not sure if you're hitting peak torque as I can't hear the clutch slipping. The 2912 definitely has a clutch (parts 6-13/14/15). Could be tripping thermal limits, or maybe they've added a more conservative current limit so that clutch only slips on a sudden bind up.

The biggest benefit I always noticed with a SDS is how much less force you need to put on the drill compared to a drill/driver and how much vibration goes back into your hands. I was doing a job where we had to drill about 50 anchors per floor into the ceiling in old 1970's concrete, I was able to do the entire floor with my SDS and while my arms got sore it was fine. My co-worker on the floor above tried to do the same with a drill/driver and his arms turned into jello by around hole 30.

Great video, great slo mo 10 out of 10

Wow, you've done a wonderful thing. You've educated a lot of folks, (myself included) about how an sds drill really works. I also presumed they had high torque based on the motor size but given how they work, they don't have a lot of need for torque. Very cool!

Great video and explanation!

I grabbed one of the Milwaukee M12 Fuel sds+ drills. For my very occasional concrete drilling I couldn’t justify the big boy. I was pleasantly surprised how well even the M12 worked for my tasks.

Great episode as usual.

Even though they will eventually do it, drill-drivers with hammer function are miserable for any project larger than hanging a picture. When I worked as an electrician (in Germany where houses are stone and concrete) we had different Hilti rotary hammers, corded and cordless. The best allrounder is probably the TE30-AVR, pretty large and heavy, but comfortable since it doesn't shake the user around too much and powerful enough for 30mm breakthroughs in concrete and 68mm core drilling.** Now that I'm an engineer I don't do that kind of work anymore, so for occasinal use I've just bought a cheap Einhell cordless rotary hammer. Works surprisingly well and is still in one piece. Especially cheaper SDS chucks are usually terrible. I don't think Einhell is available in the US, but if so I'd be interested in some reviews there. **Hilti has quick change chucks although they last thousands of hours with some grease and cleaning from time to time, I can see that these don't. On a prosumer tool like the Milwaukee I would expect to see that too.

nice! I'm a plumber so... my drill of choice is hil;ti TE 6-A36 (later TE 6-A22 22v version) and I find it awesome would love to see how TE 6-22 and TE 30-22 (both nuron) would perform compering to Milwaukee

When picking the driver to buy you should also consider that a faster (more hard hitting) driver will reduce the amount of heat put into the chisel, which seems to be the primary killer of them. The drill drivers that have a hammer function also seem to require a lot more force from the user, particularly noticeable when drilling in a ceiling. Cool footage ;)

awesome! im saving this episode for after work when i can get a whisky down me neck! :) see you in 6 hours!

Cool, loved that, thanks.

I have the Ryobi. Definitely a big help with cement and bricks. Crazy how much of a difference the hammer makes.

Lit been waiting for more rotary hammer videos

An old guy at a hardware supplier opened my eyes to how these things work. He said they used to use a star shaped chisel. Hit it, and rotate. My grandfather knew a guy who would use a surplus Garand with AP rounds to make concrete wall penetrations, until one ricocheted and nearly hit the guy.

Great lesson

Friggen love sds drills. I own a milwaukee sds but our company supplies us with big old 36 volt bosch sds drills, which we use for the heavy duty work. Saves wear and tear on our own gear but those old bosch drills are animals. They have seen alot of work every week and they just go on and on. Killed a fair few bats over there life time but they keep on running.

Excellent. Thanks

Now I want to see how Milwaukeee's M12 SDS compares.

Nice work mate, this is a very good overview of these tools. The low torque they have is something I've tried to convey in my channel as people seem to use them as a big twist drill, but really they're just dust augers. Much better off using a normal combi drill. Also your concrete seems pretty soft, do you have limestone aggregate or something?

This is timely for me. Been using rotary hammers to bust out tile and thinset on a job.

20 yrs of small scale exploration drilling here .The bit / carbide will carve a bit of material in unison with impact, it is easier to see when you add weight and more rotational torque (2000-4000lbs ). The rock will howl / resonate with the rotation as it carves, there is a lot of drilling that is done with out air hammer , when it gets hard then the 4" seco-roc down hole hammer comes out and pounds through solid rock. Would be awesome to see some downhole tools examined ( pneumatic, hydraulic) from oilfield , mining, exploration areas.

Excellent.

Super cool and interesting! Also the difference in grease between the Milwaukee and Ryobi is surprising. Really shows tgat just because it's the same company/factory they are different products.

Ran a hilti te30 last night for about 5 hours straight drilling 16, 8 plus inch 3/4 anchor holes. Drills through concrete like butter, rebar however is another story. Real pain in the ass even with rebar cutting bits

The slomo footage is beatiful and I fucking appreciate the music aswell! Great channel thank you!

This is so cool!

This is the video I did not know I needed 😂

Why not include the Bosch, Makita, Rigid, and DeWalt SDS models for the usual TTC comparison?

Really interesting stuff! The only thing I think I would like to see you guys improve on is consistency across tests. When drilling with the Ryobi it looked like it was at an angle compared to the Milwaukee. I think you also can have inconsistent thicknesses in things like poured slabs. I like the way project farm uses jigs to make sure the weight being applied also remains the same. Not that I think it would have made much difference (if any) here, but more consistency is always better.

12:10 Unfortunately, hammer drills don't always get the job done; I had to mount some TVs to the exterior hardened, reinforced concrete walls of a few Home Depots, and if I hadn't bought a proper rotary hammer I'd probably still be there trying to make my holes for the relatively small mounting Tapcons. Hammer drills have been ok in old, soft concrete floors in office buildings, but I always keep my cheap, corded Bauer rotary hammer in the truck.

Back when you could buy a "Star Drill" which was basically a SDS bit that you hit with a hammer and then rotate / repeat.

Thanks Guys.. One thing I learned while drilling a bazzilion Holes in Concrete is a bit of Finesse with the tool. Pushing too hard/bearing down slows the chipping action down. I learned to find the Sweet spot and it chews... Mike M.

It picked up where I fell asleep last night at around 10 minutes!

Hey TTC you guys should test the DCK SDS drill.

As a former Hilti tech advisor it hurts my soul to see the through-hole technique for what I assume are wedge anchors. So many manufacturers of equipment (not the anchors or drills) suggest it without regard to how much it reduces the pull-out for the anchor. Meh, not my problem anymore. Funny thing on these SDS+ battery drills is the "king" of corded SDS+ drills (Hilti) came out with the first viable battery version...then proceeded to allow themselves to be spanked in performance for almost 15 years by more than one competitor. Bosch being the first was not a surprise but there were multiple others until they came out with the third gen battery hammerdrills.

There are also manual hole drilling chisels, kinda with three straight flutes where you have to manually turn the tool between hammer strikes- basically a super slow SDS drill 😄

really interesting video 👍

I work at a mine. & the guys on shovel crews use these Milwaukees in place of an air hammer when you don’t wana fire up a mobile compressor or a diesel welder, and string out an air line for some quick material removal.

How about a video on the holding power of thread lockers, types and brands.

This is great information. You should compare a lot of the other brands SDS drills like Kobalt.

I’d love to see your guys’s opinions on the Carlyle brand cordless tools. As far as I know, they only have their 60v 1/2 and 3/8 impacts as well as a hammer drill; and a 12v 1/4 drive cordless ratchet. There is almost nothing on KZfaq about them, and for something you can order over the counter at a fairly common parts store, I feel it’s worth testing out.

Oh, SDS, one of those Bosch inventions. BTW, I think you should add some Bosch tools on that table, too.

Finally got my boschammer sds+ so this is timely

Been waiting for SDS testing!!! Any way to put the ranking chart style review together on these? Can science be used to turn PSI into a way to tell if the Ft/Lbs & Jules numbers are just marketing hype? Need to drill a serious amount of granite and cant find objective comparisons anywhere...

You should do the kobalt sds 24v. I've used one, not a power house but has a much different feel compared to a normal sds.

You should try the big Mueller Kuepps air hammer

could you try to get your hands on some other eu branded tools like vigor, would be nice to see how their impact wrenches compares to others (v4800n and v3653)

Just picked up the Ryobi version of this on sale. Super curious how they work

Cool slow mo footage. For those unfamiliar with the progression of things, those masonry bits are the evolution of straight pattern bits from back when hammer drilling meant you were drilling with a hammer. Same basic concept--the drill is a rotating chisel that either you or your trusting buddy rotated between hammer blows. The single chisel masonry bits work fine in rotary hammer applications, but more modern hand drillers prefer star drills with a pair of chisel wedges arranged in a cross pattern. The skill isn't dead by any means either. Often in national parks the use of power drills is prohibited, and neither would you want to lug around a rotary hammer if you're packing in a good ways or climbing a rock face.

Bosch is known for their excellent hammer drills, could you test one of those?

You guys should test different types of concrete fasteners/ anchors. How much torque they’ll hold before pulling out

Bosch used to build the best drills. But they also made the worst chucks. It was actually Hilti from the microstate of Liechtenstein who gave the idea to Bosch to build some standard of slide and lock. I asked Todd from PF to test them but glad you beaten him to it.

The Hitachi Koko rotary hammer does an amazing job, about 1300BPM for

It would be interesting to show how a hand drill with a 2 pound drilling hammer (OLD school) works. Also, can you drill a hole with an air hammer?

So I’m curious of the Kobalt XTR 1/2 KXIW 1424A-03. The impact driver did well.

Was legit thinking about this exact topic the other day. Now I’m genuinely thinking about picking up a Ridgid one to use in place of an air hammer for automotive lol

I wonder if there is a prime number ratio between the rotation and the impacts, making sure the impacts are almost always in a different position? Varying the downward force can help, got an old one where if too much force the drill speed stays unchanged but the drilling speed slows down.

Please test all brands 🎉 shootout 🤗 mini 12v sds+ ones and big SDS max. Who is king 👑 Great video 🎉🎉🎉

I use that same Milwaukee every day. The half second per hole at the end of the day is like 300 more holes.
