The Bosch DDS183B 18V EC Brushless Compact Tough™ 1/2 In. Drill/Driver is a powerful tool that 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. This cordless drill was fitted with an upgraded, heavy-duty all-metal chuck, for great bit grip and 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. It features the Compact Tough™ design, with a short head-length and a light weight to make handling easier, but also with professional power. 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. This is a bare-tool kit; the battery and charger are sold separately.
