Bosch Bulldog Xtreme Max SDS-Plus Rotary Hammer

The Bosch Bulldog Xtreme Max SDS-Plus Rotary Hammer is billed as a step up from Bosch's widely used Bulldog Xtreme model. Like it's predecessor, the 8-amp Max offers rotary hammer, hammer-only, and rotary-only options; and a built-in clutch, along with many other features that make drilling and chipping concrete faster and more efficient than with ordinary hammer drills. What sets the Max apart from its older brother is a built-in "shock absorber," which makes it more comfortable to use and less likely to induce repetitive-stress injuries.

The D-handle tool has a long reach for easier downward drilling.

The bits that fit these tools have identical slotted shanks; to install one, you align the shank so it enters the chuck and push until you hear a click.

On some rotary hammers, you have to loosen the side handle to adjust the depth stop — but the Xtreme Max has a convenient release button. The tool features rotary-only, rotary-hammer, and hammer-only modes.

A turret allows the cord to pivot where it exits the tool, improving flexibility and durability.

The fold-out hook is deep enough to grab a 2-by or an extension-ladder rung.
