The Bosch 11255VSR 1 In. SDS-plus® Bulldog™ Xtreme Rotary Hammer is a versatile, handy tool that features a robust 8.0 Amp motor. From anchoring to large material breaking, it gets the job done right the first time. Engineered in the tradition of legendary Bulldogs, this powerful hammer delivers 2.0 Ft.-Lbs. of impact energy and 0-5,800 no-load BPM, but it weighs just 6.7 Lbs.

The multifunction mode selector allows users to easily select among three modes of operation: rotary hammer, rotation only and hammer only. To optimize the chiseling angle, it has Vario-Lock positioning that rotates and locks the chisel in one of 36 different positions. It is Bosch’s PRO+GUARD™ dust system, helping users move toward OSHA Silica Table 1 dust compliance. The hammer is designed with an ergonomic D-handle for comfort.

It features a variable-speed reversing trigger for accurate bit starting, and a Bosch-exclusive rotating brush plate, for equal power in forward and reverse. Busy pros will appreciate the tool's HammerHook, which allows the user to hang the tool on the job, and the SDS-plus® system provides for tool-free bit changes.
