HC1/HW2Continuous machining of gray cast iron｜ Alumina ceramic (White ceramics)

First recommendation for finishing gray cast iron

High-speed performance is achievable with the thermally and chemically stable alumina ceramic blend

Effective machining at speeds up to Vc=~700m/min

Features

  • Best grade for high-speed finishing
  • HC1 grade - best wear resistance
  • HW2 grade - outstanding fracture resistance
