The most powerful tool in its class with Constant Electronic and Torque Control for the toughest applications.
Bosch high-performance motor (1300 W) with high torque for the most heavy-duty applications with large diameters (drilling, working with core cutters and holesaws), screwdriving and stirring.
Constant Electronic for more convenient work; keeps the speed constant, even under load.
Torque Control for high precision: torque preselection for uniform screwdriving.

PRODUCT HIGHLIGHTS
The GSB 21-2 RCT Professional is a 2-gear corded impact drill with constant speed and torque control designed for the toughest jobs. Its strong 1,300 W motor with high torque makes it ideal for heavy-duty applications. It features constant speed that conveniently maintains the selected work speed even under intense load. The impact drill's torque control enables torque pre-selection for high precision work.
