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


Metal chuck 1.0 - 13.0 mm
High precision with torque pre-selection preventing overtightening & damaging screw heads and threads
Protection of the user and the machine in case of overload or binding No abrupt blockage of the tool by unlatching clutch dogs and minimizing torque
Forward / reverse rotation for inserting and removing screws
Best work results with speed pre-selection Best work results with speed pre-selection for applications requiring material-specific speed
Convenient change of accessories Keyless chuck opens and closes easily
Optimized torque for screwdriving and speed for drilling thanks to 2-speed planetary gearbox
Best work results with constant speed thanks to electronic regulation of speed - even under load
Comfortable handling of the tool thanks to softgrip
Woodworking The professional power tools for woodworking from Bosch.
