Our Solid PCBN / CBN inserts display a serious of preminum performance, such as strong corrosion resistant, perform a good thermal stability and red-hardness, suitable to process cast iron, quenched steel and other kinds of ferrous metal
More Superhard PCBN cutter insert ( Polycrystalline Cubic Boron Nitride) mainly used for ferrous materials machining,like gray cast, cast iron,carbon steels, alloy steels, nickel or cobalt, etc... PCBN Diamond (polycrystalline cubic boron nitride) products is second only to diamond in hardness. The hardness allows the ability to machine hardened work pieces.
