Machine tap set M DIN 371 / 376 Form B HSS-Co 5 with progressive tap - 7 pcs.

Machine tap made from 5 % cobalt-alloyed high-speed steel (HSS). A longer tool life is achieved due to the higher heat resistance. For through-hole and blind-hole threads, in unalloyed and alloyed steels up to 1000 N/mm² strength and non-ferrous metals.

This heat-resistant material is used for machining materials with higher strength and for long cutting channels with correspondingly high heating.

The thread is cut in a single operation.
