The Bosch DDH183B 18V EC Brushless Brute Tough 1/2 In. Drill/Driver is robust and powerful, a tool that features KickBack Control and a precision clutch. KickBack Control is an integrated acceleration sensor that automatically shuts the tool down when a potentially dangerous rotational torque reaction occurs in a bind-up scenario. The precision clutch has 25+1 settings, for reduced overtightening, fewer damaged screw heads and a longer tool life. With an upgraded, heavy-duty all-metal chuck, the drill has great bit grip and torque transfer. Its efficient EC Brushless motor delivers outstanding runtime and longer motor life. It produces 663 In.-Lbs. of torque, and it has variable-speed selector - one optimized for high-torque driving (0-480 rpm) and one best for high-speed drilling (0-2,100 rpm). The DDH183 features Bosch's Electronic Motor and Cell Protection, tough Durashield housing, an LED for illumination and a long belt clip. It is an easy tool to handle, with a sure-grip side-assist handle and an ergonomic grip zone.
