The Wera 19 Piece Kraftform Kompakt 400 RA SHK Set from ITS has been designed for the HVAC industry in particular and includes a T-handle bitholding screwdriver with integrated fine-toothed ratchet for fast and safe working. The integrated ratchet with fine toothing (80 teeth) and a return angle of 4.5° eases and accelerates screwdriving without having to reposition the tool. The ratchet mechanism of the 416 RA T-handle bitholding screwdriver is completely embedded in the handle. The compact shape of the tool allows convenient working. The change of direction can easily be made using the reversing lever. The fast-rotating sleeve allows the tool to be guided safely while screwdriving and increases the working speed. The bit can be pushed into the adaptor without moving the sleeve. The lock is activated automatically as soon as the bit is applied to the screw. Bits are held securely and wobble-free. Simply push the sleeve forward to change the bit. The spring mechanism lifts the bit off the magnet and unlocks the tool. The bit can be easily removed. The rapid-out function makes it easy to remove even the smallest bits without extra tools.
