The Bosch HDS183B 18V EC Brushless Compact Tough 1/2 In. Hammer Drill/Driver is an efficient cordless tool with long runtime, and it features KickBack Control. The integrated acceleration sensor automatically shuts the tool down when a potentially dangerous rotational torque reaction occurs in a bind-up scenario. Its efficient EC Brushless motor delivers 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. It includes a long belt clip for a secure hold. This is a bare-tool kit; the battery and charger are sold separately.
