Two-piece hand taps- sets are used for fine threads with a smaller pitch than with coarse thread, as the thread profile surface is smaller than with coarse threads and the force effects on the taps are smaller. The advantage of two-piece hand taps is that the respective parts of a set share the cutting power: The taper tap (No. 1) (marked with a ring) removes 65 per cent of the thread profile and the and brings the thread into shape. The finishing tap (No. 3) has no ring marking and cuts the remaining thread profile to produce the 100% full and usable thread. The division of labour between the two screw tap makes it easier to cut a straight and clean thread by hand.

Efficient internal thread cutting.
The short structural type makes this tap usable by hand.
