A part time universal gear integrated in the handle of the screwdriver significantly increases the working speed. The turbo function can either be switched on or off by pressing a button. Turning it off is recommended for fine adjustment and final tightening or loosening of a high torque screw. The robust steel design is maintenance-free and ensures a long product life. Thanks to the Rapidaptor bit holder, the Kraftform Turbo can be used with all conventional 1/4″ hexagon bits for a wide variety of screw profiles. With the Rapidaptor function the bits can be inserted directly and can be easily removed by pushing the sleeve forward – allowing single hand operation.
