The Bosch HDS183-02 18V EC Brushless Compact Tough™ 1/2 In. Hammer Drill/Driver features KickBack Control, Bosch's integrated acceleration sensor that automatically shuts the tool down when a potentially dangerous rotational torque reaction occurs in a bind-up scenario. This reduces the risk of sudden tool reactions in binding conditions. The tool is engineered with an upgraded, heavy-duty all-metal chuck that allows for increased robustness and torque transfer. With an efficient EC Brushless motor, this drill/driver provides longer tool life as well as great runtime. One of Bosch's Compact Tough™ designs, it has a short head-length and light weight but plenty of muscle. It delivers a powerful performance, with 531 In.-Lbs. of torque, two drilling speeds (0-1,900 rpm for high speed and 0-600 rpm for high torque), an impact rate of 28,500 bpm for masonry applications and 20 1 precision clutch settings for reduced fastener damage. This tool provides an ergonomic grip zone and Bosch's Electronic Motor Protection and Electronic Cell Protection, to protect the tool and batteries from overload and overheating. It includes a long belt clip for a secure hold. The kit includes two 18V 2.0 Ah SlimPack batteries and a charger.
