BLACK RING Machine taps

The VOELKEL HSS-E machine taps with black ring are especially suitable for cast iron (GG) and spheroidal cast iron (GGG).

More recommended applications:
  • Brass and bronze, short-chipping
  • Plastics, thermosetting

Machine taps with nitrided surface:

The surface hardness is increased by enriching the surface of the tap with nitrogen. This results in high abrasion resistance and improved anti-friction properties.

Variations:
  • Machine taps (black-ring) DIN 371/376 M3-M20
  • Taps for cast iron in set of 7 pcs. (M3-M12)
