Set of 3 taps (taper, intermediate, finish).
Three-piece hand taps- sets are used for regular threads with coarse pitch, as the thread profile area is larger than for fine threads and the force effects on the taps are greater. The advantage of three-piece hand taps is that the respective parts of a set share the cutting power: The taper tap (No. 1) (marked with one ring) removes 65 per cent of the thread profile and the intermediate tap (No. 2) (marked with two rings) removes 85 per cent. Pre-cutting and reworking with the intermediate tap (No. 2) bring the thread into shape. In the last step, the finishing tap (No. 3) is used, which has no ring marking. Only this cuts the full and usable thread at the end. The division of labour between the three 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.
