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 1000 SFM

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
