The Bosch DDS183-01 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. 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 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.
