I was using a Ridgid R7121 Drill, 1/2-Inch Spade Handle Mud Mixer to drill holes in freshly poured concrete for rebar for a large garage I was building. One hole would require me putting all my weight on the drill for about 10 minutes as it vibrated my wrists. Of course spade drills are designed for mixing wet mud, not drilling into hardened mud. And it would make the drill hot.

I got tired of abusing my big mixing drills, and my wrists like that, so I got this Bosch SDS. I got it factory reconditioned from CPO. I could not tell it had been used other than the box was open. It drilled the same hole my spade drill took 10 minutes to do in 15 seconds.

I've run this drill for hours doing nothing but 1/2" rebar holes and it doesn't get hot, just keeps going. No problems yet after a few buildings.

SDS stands for slotted drive system. It uses a special kind of drill bit. Normal bits will not work without an adapter which I cover in the next paragraph. Basically you click a bit on, and the chuck locks it in place. Then only the bit is impacted in the chuck, instead of the entire chuck being impacted. Or to put it another way, only the bit moves while the chuck stays in place. This makes it a more efficient transmission of power, which is why SDS drills are all more powerful than traditional hammer-drills. Traditional hammer-drill chucks have more weight they need to move up and down.

The drill has three settings. Drill only. Impact only. And drill and impact, like all SDS drills. And like all SDS drills the handle has vibration absorption.

I first bought the Makita 1 1/8 inch SDS-Plus Rotary Hammer. There were a couple problems with it. The side grip was really hard to position because there are these notches. So the the whole grip had to be removed and then re-positioned again and push down back into place. I used it once. Then when I tried using it again a couple months later, it wouldn't work. So I returned it and bought this one.

First off, their is no comparison between the Bosch and the Makita. I used it to drill a bunch of 5/8 inch holes and it drilled through concrete like butter. The Side grip is very easy to adjust and the depth guide works great. Oh the Makita, you had to tightened the handle as tight as possible to hold the guide, and still it would slide up when drilling.

This drill has an SDS-Plus chuck. I don't think it mentioned that in the description. Overall I'm very happy with this, and highly recommend it.

I use this hammer drill for work (rough & finish carpentry, remodeling). I use it primarily for drilling holes into concrete or masonry block. I've used the chipping only function once to remove some old ceramic tile floor, worked exceptionally well.

The anti-vibration is great and easy on your hands. The case is ample sized for bit storage. I also picked up a Bosch SDS-to-adjustable-chuck adapter so I can use the drill only function for large holes in wood my cordless drill is not up for.

If you're considering this drill versus a Hilti (like I was), save $200 and get the Bosch. It's made in Germany and has one year less of warranty compared to the Hilti (no biggie, all tools break and you get them repaired).

*****update 12-30-2012******

Still using this hammer for my work tasks. It shows that the tool has been worked. The rubber impact cushion on the tip of the SDS chuck has cracked and needs replacing. I've done 3-4 tile floor demo jobs with the hammer in chip mode, so this is probably the reason for the crack. Using a Bosch tile scraper bit, I pry up with the hammer.

I've done window, door, and sliding glass door installations. Chipped stucco and concrete. Drilled out 3/4" holes for epoxied 5/8" dai. anchor bolts in concrete tie beams and through wood plates with a long auger bit. I like the size of this drill because it fits into smaller spaces (between floor joists or wall studs) during framing applications and also is easier to install smaller windows with it (think 24" x 24" fixed glass windows or smaller). I use the depth rod quite often.

The hard case has held up. I've got it jammed full of bits etc. The cord doesn't kink up and folds away well each time. The drill itself shows signs of wear on the body from being dropped and dragged. None of this effects it's performance. This tool is definitely professional grade.

This is an amazing drill. I'm a DIYer and I'm finishing my basement. When the time came to attach the framing to the poured concrete foundation, I ran into problems because the concrete had large aggregate (1-2" rocks) in it. Using my old hammer drill, it took 1/2 hour to drill a hole in it for the anchors - ugh!
When I learned about rotary hammer drills and found this one for a really reasonable price, I decided to give it a try. What took 1/2 hour before, now takes 30 seconds. I haven't noticed any problems with the chuck loosening up as some other reviews have commented on, but I haven't used it for chipping. It is an amazing tool for drilling through tough material and requires only light pressure when drilling. As a 58 year old woman, I'm also impressed with how lightweight it is and easy to use.
