Design: Very durable tool with spring tempered and adjustable fingers. The guide sleeve can be moved lengthways and therefore takes very high torsion forces.
Application: For loosening and unscrewing broken taps with 3 or 4 slots. The fingers are inserted into the slots on the broken tap and secured with the guide bush by sliding the upper retainer ring. The broken off tap piece is moved back and forth with a tap wrench until it loosens and can be screwed out.
