Products Description

PCD PCBN CBN Milling inserts RNGN tungsten carbide inserts for engine cylinder blocks

CBN, an ultra-hard cutting material consisting of polycrystalline cubic boron nitride with a metallic or ceramic binder is primarily used to machine hardened ferrous material. It's available either as a tip brazed to a carbide insert carrier or as a solid insert.

CBN Inserts can be double-sided grinding and have a longer service life. If you’re using a solid CBN tip, after one side is worn out you simply flip it over and use it again.
