Product Description

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. 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

From the Manufacturer

The Bosch 11228VSR rotary hammer has a compact pistol-grip design for inline gripping. The Vario-Lock positioning system rotates and locks the chisel into 36 different positions to optimize the working angle. The hammer features three operational modes: hammer only, for light chipping; rotation only, for drilling wood, steel, and building materials; and hammer/rotation, for drilling concrete, brick, and stone. Includes 360-degree auxiliary handle, depth gauge, and plastic case.

• Pistol-grip handle for compact ergonomic design
• Vario-Lock positioning rotates and locks chisel into 36 different positions to optimize working angle

5.0 out of 5 stars 7/8 is plenty for aged concrete, April 10, 2001

I bought the 7/8" Bosch a few weeks ago to destroy an old concrete porch, clean a large vertical crack in my cement stairs, and to generally cause havoc with a badly designed and poorly executed fieldstone walk that surrounds my little 1938 Tudor Revival House. If you live in an aging concrete house, buy this tool.

I've used the larger Bosch hammers, but could not afford them. I can rent those when needed. This one is light, and has just enough "kick" on the hammer-only function to cut through the rather soft concrete that I'm working on.

I also bought the SDS-to-3-jaw chuck adapter, and that attachment renders a really nasty drill for pressure treated wood.

The tool itself, and the Bosch hammer drill bits and chisels are all high-quality tools. It's a pleasure to use them. The alternative, a cold chisel and baby sledge, is unthinkable now.

5.0 out of 5 stars Quality, Power, Features.. It has it all, August 18, 2003

This review is from: Bosch 11228VSR 7/8-Inch SDS Rotary Hammer (Tools & Home Improvement)

I bought what to my guess is the 220v version of this hammer. Exact same feature set and spec - except for the AC line.

I went out and bought it after a drain pipe, which was laid in concerete in my house started leaking, at first I started chiseling using a cold chisel and a sledge - few hours work to get to the pipe. Then I also had to reach another point in the pipe and decided that I had enough.
Breaking through the same thinkness of concrete using the Bosch hammer (in hammering only / rotation lock mode) took less then 10 minutes, and was very easy on the operator (me).

A few weeks later I used it to set three 3/4" anchors in a concrete wall in my building. Drilling the holes - 5 inches deep each, was a breeze.
Safety clutch worked very well. In fact, I was not even aware that this hammer had a safety clutch until the bit hit a reinforcement steel rod - rotation action instantly stopped, while hamerring action continued. I didn't feel even the slightest torque blow on my hands when it happened, and, pulling the bit back was fairly simple thanks to the fact that the hammering action still functioned.

Also, the internal reduction gear makes this tool a good choice for screw driving, it succeeded where similar power, but higher RPM, electrical drills had failed.
My unit came with an automatic three jaw chuck, which works great for steel and wood drill bits, as well as for screwdriver bits, and takes 10 seconcds or less to replace with the SDS-Plus chuck.

One nitpick - for non-professional use, the SDS bits can get pricy, especially the larger diameter, longer ones: a 16x400mm bit cost me .... (then again, for non-profession use, the whole story is somewhat expensive to begin with...)

I cannot testify for the durability of the tool, since I do not use it so often - you'll have to go for other reviews for that.

This is a well built, ergonomic, powerful, and feature laden tool, all feature are useful - no toy features. and, at least my unit, came in a quality plastic case that I'm using as a day-to-day toolbox for the hammer and it's accessories.

If you can afford it, cannot rent or borrow one when you need it, and do even occasional concrete drilling or chiseling - worth the price.
