PCBN cutting insert
POMDI - HERRAMIENTAS DE DIAMANTE SA

This is a plate of cubic boron nitride compacted on a tungsten carbide substrate. The fundamental characteristic of this tool is that it can be used to machine treated steels and special alloys with a hardness greater than 55 HRC (up to 70 HRC) without the need for grinding if the operation does not require it. It can be used at extremely high cutting velocities and, as it chips the material, it does not cause significant heating in the machined part.

Its use is not recommended where tungsten carbide could be employed, but it can provide major time savings if grinding does not have to be performed on parts on which a lot of material needs to be removed. It performs excellently on high-speed tool steels.
