Hammer
I like the light weight of this tool for a jack hammer. I have used it for digging ditches with a 5 1/2 inch clay spade, and breaking up small amounts of concrete. It has worked well for everything that I have used it for. ... Read more

The Best Cordless Rotary Hammer Available
The Bosch 11225vsrh is appropriately named "ANNIHILATOR". This drill is fairly light yet powerful. I never spend more than 10 or 15 seconds on a 3/8" x 3" hole into very hard basalt. I'm starting to prefer the Annihilator over my Ryobi ER-160 (gas rotary hammer) because it is quieter and more reliable. I was skeptical about the runtime of a battery powered drill after using gas rotary hammers, but the 3Ah batteries really do last a long time and charge in about 30 minutes with the 15 minute charger. This means that you can get continuous use with only two batteries because I doubt you will discharge the battery in 30 minutes. The Annihilator is also resistant to the elements. I work on wave swept shore lines where I'm constantly getting drenched with salt water. I duct taped over the vent holes and around the battery, and the Annihilator takes the salt water shower in stride, which is more than I can say for my gas rotary hammer which will stall out when splashed. Overall, I think this drill is fantastic. It has the longest runtime and quickest recharge of any cordless rotary hammer. At $..., it's worth every penny.

Best Quality
This is the best cordless Roatary Hammer I have used. It is tops for reliability and battery life.

Coardless Powerhouse
I just got back from a bolting session in Lone Pine, CA. The new rock climbing routes are turning out to be a breeze with my new Bosch 24v cordless rotary hammer. I have used the too-heavy 36v Hilti and the nearly useless 24v Hitachi with more soreness and much less satisfaction respectively. The Bosch 11225VSRH ("H" for Hauls-A__) gets it done. I mainly do 3/8 inch holes 4 inches deep in hard to medium rock and always while hanging from a rope so ease, speed and weight are the main concerns. I am glad I bought the VSRH which gave me the 3.0 Ah batteries that just keep on drilling. .... ... Read more

bosch -vs-milwaukee
I could find no reviews on the miwaukee 1-1/2 #5315 roto hammer
so I was at a face off beteen the bosch 11241evs and 5315 milwaukee. Everyone in the business knows that bosch has made the industry standard in rotory hammers for years, but Milwaukee
has recently released this line of rotary hammers in attempt to
catch bosch.

I have used the 11241evs as a rental on a few ocasions and it is awesome. I took the chance on the milwaukee because of a five
year history of using their tools with extreme satisfaction.

Heres the scoop: I was doing an earthqauke retro fit and drilling 3/4 by 12 inch deep holes, I drilled over 50 holes in 60 year old concrete, I was very impressed that after drilling
10 consecutive holes the tool was barely warm! The effort on my
part was non existent, vibration was not at all aparent, I was simply holding the tool in place. I was really blown away at the absolute lack of effort the tool drilled these holes with.

The bosch also performs similar but seems to require a bit more effort, the milwaukee has more than an entire foot pound more of blow energy. The weight and balance of the milwaukee vs bosch
are very similar.

I absolutely love the quick lock cord on the milwaukee as storage is super easy and the replacement of the cord will never be an issue.

In hammer only mode with a bull point chisel I broke up a 4 inch thick concret slab, it hammers thru brick and block with absolute ease.

I spent $... dollars on an 1-9/16 x 21- four cutter hammer bit just to see how this tool could handle itself at max capacity, again I was blown away it drilled down 17 inches in seconds like it was going thru mud, no effort on my part no vibration no heat on the tool afterward. I would say this tool is good for all day drilling of up to one inch holes.

Downside, the power and service lights are barely visible unless your in a dark room.

I highly recomend this tool, I have milwaukee tools from five years ago that have operated for thousands of hours and are still going like new, spend the money you'll be thrilled. ... Read more

excellent for doing brute work
Used this hammer drill to bore 1-1/4 inch holes for lag bolts in foundation. Took about 5 minutes per hole when drilling to 6 inch depth. Probably would have taken less time with a sharper carbide bit, but Bosch has a powerful tool for what is a brutal job. Vibration while still present was less than I expected ... Read more

The New Champ
For quite some the Bosch Bulldog has been considered by many the best rotary hammer in it's class. Not any more. A local tool show had an impromtu side by side test between the Bosch and Hitachi reps- the Hitachi won handily drilling faster each time. I'm pleased with mine, powerful yet lightweight. ...

Amazon.com Review

The first thing you'll notice about Bosch's rotary hammer is its great ergonomics, which clearly were a major consideration in the design of the hammer. The grip and trigger mechanism are well integrated, especially the front grip, and long enough to accommodate different body styles (I've got long arms; my buddy is the opposite: we both liked the tool's feel). For a rotary hammer, design is especially critical during overhead and down-drilling operations, where fatigue can quickly rear its ugly head. The tool's vario-lock positioning is great; it gives you 36 different working angles to choose from so you can modify the tool to fit the application. Likewise, the hammer offers three operational modes: hammer only, rotation only, and hammer with rotation. We really appreciate the self-contained dust removal system, which does a great job of keeping the mess to a minimum. Are there drawbacks? Not many. The bit-changing mechanism is a little stiff and a little cumbersome, perhaps--but that's a pretty minor negative in a tool that otherwise provides such pleasant operation. The people at Bosch really know what they're doing, and it shows in this tool. --Michael Shilling ... Read more

More Dependable than Timex
This is one of the best heavy equipment/demolition tools I've ever used on the job. A few months back I needed to rent one for some work I was doing on my basement, breaking up old concrete. After I used it for a couple of days, I went out and bought one for work (I'm a demolition contractor). This is much easier to control than most 60-90lb pneumatic jack hammers. I'm not a very muscular person, but I didn't have any difficulty handling it and it never walked on me. If you need a medium to heavy duty jack hammer, I'd recommend purchasing or renting this over most pneumatic hammers because it's easy to use, it's reliable, the steel bits it uses are widely available and you don't have to lug around a huge compressor. ...
