The Bosch 1" SDS-plus(R) Bulldog Xtreme Rotary Hammer is a versatile, handy tool that features a robust 8 A motor. From anchoring to large material breaking, it gets the job done right the first time. This powerful hammer delivers 2 ft/lb of impact energy and up to 5800 no-load BPM while weighing only 6.7 lb. The multifunction mode selector allows users to easily select among 3 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 compatible with Bosch's PRO+GUARD dust system. The hammer is designed with an ergonomic D-handle for comfort. It features a variable-speed reversing trigger for accurate bit starting, and a rotating brush plate for equal power in forward and reverse. You 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.
