ultra machine tap, DIN 371 B, HSS-Co, red ring, through-hole for M5

Red ring, HSS-Co, type B

Prime quality for application in series production. Ultra-modern manufacturing technology for maximum productivity.

Application area:

Through hole for tool steels up to 1,200 N/mm²


Up to M 10 DIN 371/from M 12 DIN 376



  • Special groove and cutting geometry for materials that are difficult to machine
  • Smooth tool surface for low-friction chip removal


  • Particularly hard TiCN* (titanium carbo-nitride) coating for additional protection of cutting edge
  • Coating ensures a smoother surface in the groove and in the thread profile
  • Surface smoothing ensures reduced torque

Recommended applications

  • Cutting speed up to vc = 8–12 m/min
  • Use of cooling emulsion 6–8%, oil cooling alternative

Field of use

  • Heat-treatable steels up to 1200 N/mm², titanium alloys, heat-resistant steels, nitrided steel, reinforced plastics
