Needed a hammer drill to bore a few holes in concrete, nothing super heavy duty, just a middle of the line hammer drill. This drill meets all these requirements and quite easily got the job done.. Rated 8 Amps there is little chance of tripping a 15 amp breaker. A medium duty extension can be used, the SDS-plus bits are not too expensive. The auxiliary handle can be adjusted with a twist, the depth gauge can be retracted, the variable speed is built into the on/off trigger. The reverse switch is a plus if/when bits get stuck and flips to either position verily easily. The multi function switch has 3 selections, rotation with hammer, hammer only or rotation only. With the purchas of a SDS-Plus shaft chuck, the drill will function as a normal drill with a 3 teeth 1/2 inch chuck so normal wood boring drill bits can be used. The SDS plus bits fit easily into the drill with just twist and push. A small tube of lubricant is included in the case to be applied to the slots on the SDS bit. A pull down on the chuck releases the bit. It has an integral clutch to minimize torque reaction. This high quality hammer drill meets all requirements without breaking the bank.
In retrospect a purchase of a BOSCH SDS "MAX" hammer drill along with a SDS "MAX" to SDS "PLUS" chuck would allow the use of both SDS PLUS or SDS MAX drill bits. By purchasing the SDS PLUS drill only SDS PLUS bits can be used, I know of no adapters allowing for an SDS PLUS to SDS MAX chuck adapter - hope this suggestion is helpful.
Great handle and adjustments, drills thru solid rock like it was gypsum board. I like the ergonomics of this model compared to the longer version. Easy to adjust and this Rotary Hammer gets the job done. This is a must for anyone who has to drill thru hard rock, concrete, brick or stone. I am telling you the truth that this thing makes the job go so smoothly. I was beating myself up by trying to use a regular carbide bit and standard drill. You may not need to use this very often, but when you do you will be very glad you purchased it. SDS is the way to go.
I really wanted to give it 5 stars, but one minor issue made me take away one. The depth guide would slip often and cause me to drill holes deeper than required. I ensured the rod was properly inserted but it still slips from the vibrations.
That aside, it performs brilliantly for domestic use! My Milwaukee hammer drill is much slower when drilling concrete and the vibrations from it had hurt my wrist. Took me a few days for the pain to go away. That was the reason I decided to invest in a rotary hammer instead. This Bosch punches through concrete extremely fast, especially when compared to a hammer drill, the vibrations on the handle is minimal and it is far less noisy than a hammer drill also. Because it drills very efficiently, there isn't much side to side bit wandering, so the holes end up exactly where you want them to be. The hammer only mode comes in handy also. It is a great product and from my research, one of the most powerful in its price range. I would strongly recommend this.
This drill has performed flawlessly over about two months of hard use. With a fresh 5/8 dewalt bit it chews through 5000 psi concrete at a rate of almost one inch every 10 seconds or so. I was used to using a similar Hilti model that is double the price, but the Bosch unit is every bit as good if not better. The support handle actually feels much stronger and better mounted than the one on the Hilti model. It also doesn't seem to cause as much runnout or "hole wallerin" as I hear people say. A dewalt model I used wanted to run around the hole in concrete which made red-head anchors not want to engage and lock up when tightened. I can say a 5/8 SDS Bit in the bosch makes a nice and tight 5/8 hole that is perfect to lock in anchors. I'm extremely satisfied with my purchase!
If you've ever struggled with a standard hammer action drill into concrete, then using this beast, although a little heavy, is so easy. - it literally slowly sinks into the concrete with minimal effort.
A standard hammer action drill uses a clutch that not only spins the bit, but vibrates it in and out, very fast, but not very powerfully - thus the user needs to apply a lot of force to drill into concrete.
A rotary hammer uses an electro - pneumatic piston to push the bit in and out. - This allows a much more powerful blow to be driven into the concrete, meaning less effort required for the operator.
The reason for an SDS chuck - the hammer action in this is too much for a standard chuck to hold onto - the bit would just stop spinning.
The rotary part can also be turned off, allowing a chisel bit to used. Great for taking up floor tile in bathrooms - in fact that's my next task for this equipment, I expect it to be an easy task.

Description
Bosch 1-1/8-Inch SDS Rotary Hammer
My builder had one of these and I had to get one. So far i have removed brick and mortar like nothing! Also drilled in mortar and used it to lift tile and clean thinset. My builder used it on concrete. Awesome tool!
In the process of building a deck, we had a task of drilling 5" deep holes in hardened concrete to attach a 2-by to a concrete wall with large tap con screws, we started off using a heavy duty Makita hammer drill. Using that, a hole had to be drilled through the 2-by with a drill bit for wood, then we switched over to the hammer drill. Pushing hard for about a minute while running the drill at high speed resulted in a hole deep enough for the 5" Tapcon screw.
Over the weekend, I ordered the Bosch SDS rotary hammer. Round 2 of attaching the board to the wall went much easier. No predrilling was required to bore through the board. Instead, just place the concrete bit on the board and let it rip. With very little fanfare (or vibration), it almost melted into the concrete. Drilling the hole took maybe 10 seconds or less.
I can't speak to the durability, but it seems that for the price when compared to the standard bearer (Hilti), it's very affordable.
I used this hammer to remove the tile from 12 motel bathrooms that were thinset to a concrete floor. It took about an hour per floor using a bosh tile chisel. This machine did the trick, the job would have been impossible if I didn't have it. At first I didn't think it was going to work real well, then I figured out that if you go at the tile with the chisel at a steep angle to the floor this hammer will vibrate it right off. I touched up the edge on the chisel about 3 floors, you will notice when the chisel is getting a little dull. One thing, it gets dusty as hell. This was well worth the money.
Works great! Purchased primarily for drilling holes in granite for anchoring and splitting with feather-and-wedges. Good drilling speed in granite with 5/8 bits. I've gone up to 10" deep to help control the split on larger rocks. For best results (especially in granite) be sure to use the Bosch X5L bits which have a solid carbide tip, rather than just a carbide cutter. My only quibble is that it takes a fair amount of pressure to hold the trigger in the on position, and there is no trigger lock.
I bought this for my son-in-law for his birthday. He said that he loves it and has been wanting one for some time now. That's all I can really say about it as I didn't use it personally. He picked it out and I bought it. It was something he needed for his line of work, so if he's happy with it, I'm happy.
