Polished section for threading
The point angle or the shape for chasing tools is depen-
ding on the type of thread.
See also:
The measure X must be larger than the depth of thread.
Make save that no chip angle is being ground as in this
case there would be a strain of the profile.

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.
Bolts and nuts with large thread diameters, deviating thread pitches or special types of thread,
right-handed and left-handed threads may be produced by threading. For this manufacturing
there are as well tool holders and drill rods with exchangeable indexable inserts (one-edged or
multiple-edged).
