The most powerful tool in its class with Constant Electronic and Torque Control for the toughest applicationsBosch 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 stirringConstant Electronic for more convenient work: keeps the speed constant, even under loadTorque Control for high precision: torque preselection for uniform screwdrivingFEATURES:Metal chuck 1.0 ? 13.0 mmHigh precision with torque pre-selection preventing overtightening & damaging screw heads and threadsProtection of the user and the machine in case of overload or binding. No abrupt blockage of the tool by unlatching clutch dogs and minimizing torqueForward / reverse rotation for inserting and removing screwsBest work results with speed pre-selection for applications requiring material-specific speedConvenient change of accessories. Keyless chuck opens and closes easilyOptimized torque for screwdriving and speed for drilling thanks to 2-speed planetary gearboxBest work results with constant speed thanks to electronic regulation of speed ? even under loadComfortable handling of the tool thanks to softgrip
