This hammer drill's powerful EC Brushless motor delivers 535 In.-Lbs. of torque and 0-28,500 bpm. It has variable speed settings; one for high-speed (0-1,900 rpm) and one for high power (0-600 rpm). The cordless drill has KickBack Control to reduce the risk from sudden rotational torque reaction, a 20+1 precision clutch; an all-metal chuck that provides durability and a longer belt clip.

Reduce the risk of injury from kickback or bind-up situations with Bosch Active Response Technology(TM) featured in the new the Bosch HDH181X 18V Brute-Tough(TM) 1/2" Lithium-Ion hammer drill/driver. The innovative on-board acceleration sensors automatically shut the tool down when a potentially dangerous torque reaction occurs. The Bosch engineered 4-pole motor provides 752"/lbs of torque, making it powerful and efficient for drilling a broad range of high torque bits such as spades and augers. As with all Bosch best built cordless tools, advanced electronic motor and cell protection help prevent overheating and overloading for extended tool life and runtime. A built-in LED light illuminates the workspace for optimal visibility. All-metal Bosch gears and Durashield(TM) tool housing hold up in even the toughest jobsite conditions, including withstanding multiple 12 Ft. drops onto solid concrete. The HDH181X is compatible with all Bosch 18V Lithium-Ion batteries and chargers for maximum versatility.
