The Bosch DDH183-01 18V EC Brushless Brute Tough 1/2 In. Drill/Driver Kit features a drill with power and great runtime, as well as two 18V 4.0 Ah FatPack batteries and an BC1880 18V fast charger (which can charge a spent 18V 4.0 Ah battery to 80% in 25 minutes and to 100% in 35 minutes). The tool has an efficient EC Brushless motor for runtime and longer motor life, as well as producing a max of 663 In-Lbs. of torque. KickBack Control provides more user security; it's an integrated acceleration sensor that automatically shuts the tool down when a potentially dangerous rotational torque reaction occurs in a bind-up scenario. The drill has a precision clutch with 25+1 settings, for reduced overtightening, fewer damaged screw heads and a longer tool life. It also has variable-speed selector - one optimized for high-torque driving (0-480 RPM) and one best for high-speed drilling (0-2,100 RPM). With an upgraded, durable all-metal chuck, the drill has great bit grip and torque transfer. It 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.
