PCBN Series
Superhard polycrystalline cubic boron nitride tools for hardened steel, cast iron and superalloys.
Application material: Hardened steel HRC 45–70, grey / ductile cast iron, powder metallurgy steel, superalloys
Coating options: Uncoated (CBN), TiN / TiAlN coated
Series overview
PCBN is second only to diamond in hardness and retains its cutting edge at temperatures far beyond carbide limits, enabling hard turning that replaces grinding. Our CBN grades are tailored for finish and continuous cutting of hardened components, interrupted cutting of cast iron and high-temperature alloy machining.
