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.
