A range of manual HSS metric left-hand threaded hand tap bits offered in a 3-part set (taper, intermediate and finishing tap bits).

These high-quality tap bits from Dormer are ideal for tapping in blind or through-holes.

Threading taps are used to create threads for bolts in materials like metals and plastics. Threading taps work like a drill but due to the unique shape of a tap, when they are screwed into a piece of material, screw threads are created.
