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

Bosch’s 11224VSR 7/8-inch SDS-plus bulldog rotary hammer offers the utmost in versatility and functionality thanks to its compact size and powerful motor. Ideal for use during overhead and down-drilling operations, the 11224VSR features an ergonomic design with a D-handle to increase control yet reduce user fatigue. Multiple working angles and operational modes make this rotary hammer a must-have when working with concrete, brick, stone, and masonry.

11224VSR 7/8-Inch SDS-Plus Bulldog Rotary Hammer At a Glance: SDS-plus bit system allows for tool-free bit changes and automatic bit locking 1.6 foot-pounds of impact force; 0-6,150 BPM; 0-1,100 RPM Powerful 6.9-amp motor for fast removal under load UL listed and OSHA compliant Backed by one-year limited warranty

The 11224VSR's lightweight and ergonomic design makes it ideal for overhead applications (view larger).

Functional Features
The SDS-plus bulldog rotary hammer operates in three different modes for convenience and versatility: hammer/rotation for drilling concrete, stone, brick, and masonry; hammer only for light chipping applications with chisels; and 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 minimizes torque reaction, and the variable-speed reversing trigger allows for accurate bit starting and easy removal of fasteners or bound bits.

Powerful 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 11224VSR’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. Bosch-exclusive Vario-Lock positioning rotates and locks the chisel into 36 positions to optimize your working angle.

Toolhounds know the old saying regarding a tool that does only one job, but does it like nothing else can. That's certainly the case with this demolition hammer from Bosch. It may not be versatile, but it absolutely does its job.

This model is a favorite because it's so user-friendly, weighing in at under 23 pounds and about as many inches in length - practically diminutive next to its competition. Its power, however, is not at all relative to its size, offering a range of impact energy from 4.4 to 18.4 ft./lbs. and up to 1,890 blows per minute, reducing tough concrete to dust.

Part of the beauty of this hammer is that it actually doesn't want you to do the work for it; we found that exerting force on it actually slows you down. Instead, firm, steady pressure got us the best results. We particularly like the design of this hammer; instead of the traditional linear approach, Bosch built it more like a pistol, and that may (or may not, we're not rocket scientists) be part of why so little vibration is felt. The rear handle is generously padded, and the auxiliary handle rotates 360 degrees so you can set it exactly where you need it. Another check in the ergonomics column comes from the electronic feedback system and the soft start it provides, keeping torque to a minimum.

Bit changes are fast and easy with the SDS-max system. Just twist the bit and push it in until it locks into place automatically, and you're ready to work. The vario-lock is an ingenious feature that lets you position your spade or gouge at exactly the attitude you need. While in the vario-lock setting, you just rotate the locking sleeve to one of 12 positions at 30-degree increments, and an easy twist of the locking sleeve secures the bit in position.

The variable speed dial lets you choose from six speed settings, appropriate for chipping everything from plaster work up to concrete, and the circuitry will keep your set impact rate constant between no-load and load conditions.

It's an investment, to be sure, but this tool will pay you back in spades.--Kris Jensen-Van Heste
