Part 3....drilling into concrete with 1/2" bit. DeWalt: Drilled from: 0:40-2:12 Total drilling time: 1 minutes, 32 seconds Average time per hole: 30.66 seconds Hilti: Drilled from: 2:36-3:55 Total drilling time: 1 minutes 19 seconds Average time per hole: 26.33 seconds https://www.youtube.com/watch?v=RN0XFXYhqUE&feature=c4-overview&list=UUm20a1xnKrDbG3ZLpPxemcA

So here's a more telling video. Both rotary hammers drilling with the same 3/16" bits into concrete. I come up with times as follows, using the timer on the video: Hilti: Drilled from: 2:04-4:19Total drilling time: 2 minutes 15 secondsAverage time per hole: 11.25 seconds DeWalt: Drilled from: 4:44-7:36Total drilling time: 2 minutes, 52 secondsAverage time per hole: 14.33 seconds https://www.youtube.com/watch?v=19iF_4vDV38

Yeah, the DeWalt is 1.7 ft lbs of impact energy, the Hilti is 1.5 ft lbs The DeWalt is 4100 ipm, the Hilti is 5200 ipm.

I'm going to do another comparison with 1/2" bits once I locate some concrete I can drill up. I've done 1/2" holes with the DeWalt and it was pretty smooth.

Yeah, it's hard to time it exactly, but I came up with 1:46 for the Hilti and 1:48 for the DeWalt. I wonder if there would be much of a difference drilling 3" deep in concrete instead of 1¼" granite that's breaking out on the back.

And the 36v is only 6.25 pounds! Bosch has their stuff together when it comes to hammer and rotary drills.

Ahhh...that one is pretty. I want it lol. I would love to compare that one to these. I think right now, if I didn't own an SDS and didn't have all of the DeWalt stuff and I had to go buy one....I would get the Bosch. That thing is nice...and only 5.7 pounds!

This is the one I have. It works really well. Heats up a garage in no time. I will say if you need a battery, get one off Amazon. You'll pay twice s much at a Batterys Plus.

I'm uploading a video s we speak. Which Bosch model do you have again...?

Yeah, it's a cool tape, but honestly not sure how well it will hold up. It's already starting to extend slower. Almost to the point where I have to pull it out by hand. For $30 or whatever it was, it should be bullet proof.

Photo comparison:

I'm not sure how long of a comparison this will turn into, but I figured it would be best to start a dedicated thread. This will be to compare the Hilti TE 4-A18 and the DeWalt DCH213 cordless SDS rotary hammers. Primary use is for drilling 3/16" x 2½" (±) holes in concrete & masonry with occasional ½" x 3" holes for concrete anchors. 06.15.12: Purchased DeWalt 20v Max DCH213 Cordless SDS Rotary Hammer with to 20v Max 3.0Ah batteries. I've drilled a few thousand 3/16" holes over a year and a half without issue. Zero complaints. 01.17.14: Purchased Hilti TE 4-A18 Cordless SDS Rotary Hammer with two 21.6v 2.6Ah batteries. Immediate thoughts when comparing the two tools: Weight: If holding with one hand, the tool is noticeably nose-heavy compared to the DeWalt. This likely won't be an issue because once drilling, the front is supported by the bit anyway. The DeWalt weighs in at 7.0 pounds with the 3.0Ah battery. The Hilti weighs in at 7.6 pound with the 2.6Ah battery. Size: The size is virtually identical. The Hilti is approximately ¾" longer and the battery and the body/battery area is noticeably thicker. Features: The DeWalt has a hammer/chisel-only mode, the Hilti doesn't. The DeWalt has an LED light, the Hilti doesn't. The forward/reverse switch on the Hilti is much easier to access and operate than the DeWalt. The switch on the Hilti is directly above the trigger with no obstructions and is about twice the length of the DeWalt. The DeWalt has a 'ledge' between the trigger and the switch that makes it difficult to access and operate. Performance: Too soon to tell. I drilled a few 3/16" holes in a 2" patio paver and it went through great. Drilled a few with the DeWalt and honestly didn't notice any difference. Perhaps the difference (assuming there is one) becomes more noticeable when drilling larger holes. When I get time, my plan is to put both tools head-to-head by drilling a couple dozen 3/16" holes, then a couple dozen 1/4" holes, then a couple dozen 1/2" holes. First, I need to locate a suitable object or material to perform the test in. I don't really want to make Swiss cheese out of my driveway or garage floor.

I tried to find videos on it, but couldn't locate anything. Have you guys reviewed this one, Eric?

Yeah, I got 8 of the drill bits....pretty good deal.

Got it for just shy of $450 including shipping. lol....we shall see....

Hey no problem! I'm going to hold onto it until I make sure I like the Hilti, then I'll put it up for sale.

Mine's about to be for sale if interested.

So did my wife lol

Well I don't mind giving them a hand.

Well after all of the cordless rotary hammer talk in the other thread, I decided the Hilti TE 4-A18 would be the one I would get if I ever decided to move on from the DeWalt 20v that I have. Got looking around on eBay and found a deal I couldn't pass up. A little nerve racking buying one without ever having used one or put hands on one, but everything I've read pretty much describes it as easily being the one to beat when it comes to cordless SDS rotary hammers. Seller's photos are attached.

Got two...one for me for who knows what, and one for someone else......for who knows what. But for $9, who cares!

I picked up eight of the Rigid drill bit sets for $4 each. I use 1/8" and 3/16" bits a ton so this was a pretty good deal, plus once the bits are used up, it gives me eight nice cases for fasteners, anchors, etc.

I'm surprised you would opt for the DeWalt. I'm a DeWalt fan and it would still be my 4th or 5th pick lol. Yeah, I actually need to pick up a sign permit Monday morning and guess what's about two blocks down....the local Hilti store. I'll probably stop in.
