CP1Roughing gray cast & ductile cast iron / CVD coated carbide

CVD coated carbide grade ideal for roughing

Highly efficient and stable machining even during low cutting speed conditions

Outstanding wear resistance at cutting speeds of Vc=~300m/min


  • Ideal for roughing of gray and ductile cast iron
  • High degree of wear resistance and stable machining due to thick laminated TiCN + Al2O3 coating
  • Excellent adhesion resistance with the uniquely smooth rake surface treatment

Tooling application

Gray cast iron/Ductile cast iron
Roughing with scale

Coating composition
