Cermet cutters in the cemented carbide industry generally refer to TiCN/TiC/TiN as the hard phase, adding Co or Ni as the bonding phase, in many occasions, A tool for adding more than one nitride, carbide and carbon nitride in IVB, VB and VIB group metals of the periodic table as an additive to enhance the mechanical and high-temperature properties of cermet.

Cermet tools can not only rough and finish high hardness materials, but also rough milling and intermittent cutting. Cermet tools can process high hardness materials that are difficult to process with traditional tools; The wear resistance of cermet cutting tools is better than that of ordinary cutting tools, reducing the number of machining tool changes, and can be used for high-speed intermittent cutting. Cermet cutting tools strengthen bonding, improve the high temperature performance, thermal conductivity and thermal shock performance of cermet cutting tools.
