The Bosch HDS183-01 Drill/Driver features 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. The drill was engineered with an upgraded, heavy-duty all-metal chuck that furnishes increased robustness and high 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 and 20+1 precision clutch settings. 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.
