Blind hole for steel

Description

Blue ring, HSS-Co, type C Prime quality for application in series production. Ultra-modern manufacturing technology for maximum productivity.

Advantages

  • GeometrySpecial groove geometry for low-friction chip removalDesigned for long-chipping materials
  • Coating/surfaceTiN (titanium nitride) coating to prevent the formation of built-up edges, inhibits the adhesion of materialCoating ensures a smoother surface in the groove and in the thread profileSurface smoothing ensures reduced torque
  • Recommended applicationsCutting speed up to vc = 10-20 m/minUse of cooling emulsion 6-8 %, or alternatively oil cooling
  • Area of applicationSteels up to 1000 N/mm²; structural and case-hardening steelsSpheroidal graphite iron, black malleable iron

Advice

  • Up to M 10 DIN 371 (reinforced shaft)/from M 12 DIN 376 (with thin shaft)
