Screwdriver for 4-groove taps.
Design: very durable tool with springy, hard, adjustable claws. The guide bush is moved lengthwise and thus absorbs very high twisting forces.
Application: for loosening and unscrewing damaged taps with 3 or 4 grooves. Claws are inserted into the grooves of the damaged tap by moving the upper fixing ring and secured with a guide sleeve. With a broken tap, it is rotated back and forth using a knob until loosened and pulled out.
