With its power-to-weight ratio, the device allows for optimal handling, especially for overhead screw applications and in tight spaces. The 2-speed gearbox provides up to 18 Nm of torque (soft screw case) for powerful screwing up to 7 mm. Bosch Electronic Cell Protection (ECP) safeguards the battery against overload, overheating, and deep discharge. The battery-powered drill driver features three LEDs that indicate the charge status. The GSR 12V-20 Professional has an integrated LED to illuminate the work area, even in dark spots.
