NTK CUTTING TOOLS

Roughing 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

Features

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

① A very smooth layer of fine grain Al₂O₃ ② Fine column shaped grain TiCN layer ③ Ultra - hard cemented carbide base material
