This Bosch hammer drill/driver delivers next-gen innovation with power for demanding materials and applications anywhere on a jobsite. This GSB18V-975C 18V Brushless Connected-Ready 1/2 In. Hammer Drill/Driver has a powerful brushless motor, that provides efficient power for up to 975 In.-Lbs. of max torque and 0-31,500 beats per minute (bpm), but weighs only 3.4 Lbs. (tool only, not including battery). It has variable speed settings: high speed (0-2,100 rpm) and high power (0-480 rpm) and a precision clutch with 25 settings to reduce fastener damage. Rapid mode selection switches between drilling mode and driving mode without needing to adjust the clutch. The drill/driver has KickBack Control, which reduces the risk of injury from sudden rotational torque reaction in a bind-up scenario. The drill features connectivity (module sold separately), which links users to a connected device via the Bosch Toolbox App to customize settings and receive feedback. It has an all-metal chuck that provides durability and a longer belt clip for a more secure hold. The kit features two CORE18V® 4 Ah Advanced Power Batteries, allowing you to keep the power and lose the weight.
