Cutting Tools
1
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.
