The Bosch DDS183-01 18V EC Brushless Compact Tough™ 1/2 In. Drill/Driver Kit has a drill with KickBack Control, which reduces the risk of sudden tool reactions in binding conditions. This integrated acceleration sensor automatically shuts the tool down when a potentially dangerous rotational torque reaction occurs in a bind-up scenario. It is engineered with an upgraded, heavy-duty all-metal chuck that allows for increased robustness and great 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 torque) and 20 1 clutch settings. This tool provides an ergonomic grip zone, a long belt clip for a secure hold, and Bosch's Electronic Motor Protection and Electronic Cell Protection – to protect the tool and batteries from overload and overheating. The kit includes two 18V 4.0 Ah FatPack batteries and a charger, to deliver all-day power, and a long belt clip for a secure hold.
