This Bosch hammer drill delivers next-gen innovation with brute tough power for demanding materials and applications anywhere on a jobsite. This GSB18V-755CN 18V EC brushless connected-ready brute tough 1/2 in. hammer drill/driver features (which connects to an optional connectivity tool module), linking the tool to the free Bosch toolbox app on a connected device for enhanced tool control and detailed feedback. It has a powerful EC brushless motor, that provides efficient power for up to 755 in. lb. of torque and 0 to 31,500 beats per minute (bpm), but it weighs only 3.5 lb. (tool only, not including battery). It has variable speed settings: high speed (0 to 2,100 RPM) and high power (0-480 RPM). The drill has KickBack Control, which reduces the risk of injury from sudden rotational torque reaction in a bind-up scenario. The 25+1 precision clutch reduces fastener damage. It has an all-metal chuck that provides durability, and it has a longer belt clip for a more secure hold. This is a bare-tool kit, the battery and charger are sold separately.
