rotary hammer

Bosch bills this as the fastest, longest lasting breed of rotary hammer. The totally redesigned BULLDOG Xtreme outlasts the competition in both speed and performance. A side-mounted multi-function selector allows 3 modes of operation: rotary hammer, hammer-only and rotation-only mode. Vario-Lock Positioning rotates and locks the chisel into 36 different positions to optimize your working angle. The patented rotating brush plate provides equal power in both forward and reverse, so you get as much torque and speed coming out as you do going in. There are also some nice minor touches, like how the cord turret has a 35-degree pivot for added flexibility and longer cord life.
