The 11224VSR's lightweight and ergonomic design makes it ideal for overhead applications (click to enlarge).
Functional Versatility
The 1124VSR SDS-plus bulldog rotary hammer operates in three different modes for convenience and versatility. The first operation is the hammer/rotation for drilling concrete, stone, brick, and masonry. The second operation is hammer only for light chipping applications with chisels. The third operation is rotation only for drilling in wood, steel, and building materials with the optional chuck. The SDS-plus bit system makes for tool-free bit changes and automatic bit locking—plus it provides dust protection and the maximum impact energy transfer rate. Its integral clutch minimized torque reaction, and the variable-speed reversing trigger allows for accurate bit starting and easy removal of fasteners or bound bits.

Prevailing Performance
With a 6.9-amp, 120-volt motor, the bulldog rotary hammer packs a punch despite weighing only 6.5 pounds and measuring 17-1/2 inches long. Its no-load speed of 0-1,100 RPM and no-load beats per minute of 0-6,150 BPM—along with 1.5 foot-pounds of impact force—make the 11224VSR ideal for use with a variety of materials. It is capable of a 2-1/2-inch maximum hole diameter in concrete (thin-wall core bit), a 1-inch maximum hole diameter in wood, and a 3/16-inch to 5/8-inch optimal concrete capacity range.

Compact and Ergonomic
The SDS-plus’s 360-degree auxiliary handle is equipped with a built-in depth gauge, which provides users a wide range of movement while maintaining consistent drilling depth. Its D-handle design delivers additional control, especially in down-drilling or overhead applications that typically cause user fatigue. Exclusive to Bosch, the Vario-Lock positioning rotates and locks the chisel into 36 positions to optimize the perfect working angle.

What's in the Box
The 11224 VSR includes one Bosch 11224VSR 7/8-inch SDS-plus bulldog rotary hammer, one auxiliary handle, one depth gauge, and one carrying case.

I bought the 11224VSR to replace my old 11212VSR, which I have owned for about ten years. I was pleasantly surprised to find that the new 11224 is made in Germany, especially since these days so many power tool manufactures are shifting operations to Mexico, China and Taiwan. Even the free promotional SDS-Plus bit set that was included with the kit when I bought it is German made.
The 6.9 Amp motor and stop-rotation feature make the 11224 excellent for light chipping and scaling with 3/4"or 1-1/2"wide chisels respectively. It is reversible, so it is ideal for installing and removing light to medium duty small masonry fasteners. The 7/8" solid bit capacity gives it the ability to make a hole in concrete large enough for pass 1/2" EMT through. With the available, impact rated 1/2" locking geared chuck adapter, you can use the tool for drilling in wood or metal in the rotation only setting or with standard straight shank percussion masonry bits in the hammer/rotation mode. The adapter is not something that I use all the time but was glad to have had it on several occasions because it kept me from having to stop what I was doing and run out to the truck to grab a regular 1/2" drill just to make a couple of holes in a metal enclosure or 2X floor joist.
I also use it with the 1-1/8" and larger Bosch thin-wall core bits with an 11-7/8" shank for drilling through ceramic, granite and marble tile floors and poured concrete walls to run conduit and pipe. The Bosch thin-wall core bits are sometimes hard to find locally and are also expensive, but are well worth it because they make very clean holes and substantially increase the capacity of this small hammer.

I do a lot of brick work, and found myself having to install footings over and in a lot of hardpan. I bought the Bosch Rotary Hammer hoping I could avoid all the pick work which was killing my back. I have to say this machine worked great. I used a chisel bit and it cut through the hardpan like butter. I was able to form my footings by cutting the exact size in the hard soil. I am writing this review because after a couple of weeks of 8 hour days using this Hammer, I realized that in addition to saving my back, the machine was quite durable.
Later I cut through a bunch of cement flashing along my house foundation to lay some footings and again the Bosch did a great job. Oh.. I did try drilling some holes in concrete with complete success. I recommend the Bosch rotary hammer, one of my favorite tools!!

I think of the times I've spent over the years leaning with all my might on a regular drill trying to punch holes in masonry. Little did I know, but using a regular drill on masonry is akin to pushing a nail into wood rather than hitting it.

I started to catch on when I opted for the hammer drill version of my recent cordless drill purchase. Pleased with the performance of that machine, I decided to move up to this Bosch corded rotary hammer for some bigger holes I needed. I have not been disappointed. In fact, the first time I used this unit, I was dumbfounded by the ease in which it tore 1/2" holes into some old concrete. With this unit, I'd have to rate boring in concrete as at least as easy as boring in wood, and much easier than boring in steel.

Yes, it's a lot of money for someone like me who will use it only occasionally. I think what won me over was the versatility of this machine, with the light chipping function as well as the capability to be a high torque regular 1/2" vsr drill. (With the purchase of the adapter - about forty bucks).

At least now I'll be looking for reasons to drill into concrete rather than looking for reasons to avoid it!

I was told by some people that I needed a bigger tool for the demo job am doing, but rave reviews for this tool here and on the Fine Homebuilding forums, not to mention the $200 more I'd have to spend on the next-level Hilti, convinced me to try the Bulldog. I bought it here when it was on sale with the bit set, which was great, as those bits are not cheap. It has worked like a dream, and I have worked it hard on old plaster on top of gypsum lath, and cinder block. True, those are not granite, but I ran this tool as full time as I had energy for, 8 hours a day and it never even got really hot. Vibration isn't too bad, either.
The feature that lets you reposition the axis of the SDS bit is easy and I use it a lot more than I would have thought.

I own a small home improvement/remodeling company. I've used this for some small demo jobs ie: removing ceramic tile with a 1.5" chisel as well as drilling a variety of holes into masonry/concrete. It's had plenty of power and works great. The Fit/ finish is excellent and the case has plenty of room for all my bits. I highly recommend it!

Working for a disaster restoration company in so. cal. doing piece work construction, I need tools that do the job quickly and reliably without taking up half the bed space in the back of my truck. I am required to be a jack of all trades so to speak. This rotary hammer has never let me down! Just a word of caution- If you are planning to demo. the old garage or build a modern marvel, buy a bigger hammer. Remember- don't bring a knife to a gun fight! Use your better judgement and you'll be fine. As for the other 90% of us this tool will do just fine!
