Cutting Tools
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 slots
(order no. 1852) or 4 slots (order no. 1848). 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.

Tap extractor set
Design:
Solid carbide, type N. The Tap borer has 3 blades.
Application:
Extraction must take place dry at ca. 1500–3500 rpm. With use of the
right tap bore-out tool, the core of the tap is quickly bored out and the rest of the tap can
be cleanly blown out of the drill hole. The workpiece must be clamped very steadily so
that movement does not happen at higher speeds. A centring must be produced first by
starting the tap bore-out tool up several times if the tap has broken off at an angle.
Boring out can only be started now. Furthermore, the chips should be removed by
"air blow" several times.
A vibration can be felt just before the end of the bore-out process. The extractor should
now be removed.
The new thread can then be cut with a tap. Due to the high stresses caused by boring out,
the cutting edges of the tap bore-out tool need to be resharpened from time to time.
