Polished section for threading
The point angle or the shape for chasing tools is depend-
ing on the type of thread.
See also:
The measure X must be larger than the depth of thread.

Tapping of external and internal threads
Threads with smaller diameters and standard thread pitches should be tapped manually on the
lathe with screw-taps or dies by turning the clamping chuck as this is more simple to produce.
CAUTION!
Pull off the mains plug of the lathe if you want to tap a thread as described above.
