Kraftform Kompakt Turbo 1 Screwdriver Set, 19 Piece - 

Many users would like to be able to carry out screwdriving processes faster without compromise. With a screwdriver that is precise, allows powerful screwdriving, and is much faster than a conventional screwdriver. A part time universal gear is the solution: integrated in the handle of the screwdriver, it significantly increases the working speed. The Kraftform Turbo accelerates the screwdriving in a purely mechanical way. 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.
