Cermet Insert Grades
KYOCERA is known as the leading manufacturer of cermets.
Cermet is composed of the words Ceramic and Metal. Typical materials used in cermets
are TiC, TiN, TiCN and NbC. Designed to provide long tool life and excellent surface
finishes, cermets combine toughness with superior wear resistance.
PVD Coated Cermet
PVD Coated Cermet is coated on cermet substrate with a thin layer of high wear
resistance and high adhesion resistance by PVD (Physical Vapor Deposition)
technology. Generally because of the low processing temperature of PVD compared
with CVD, PVD Coated Cermet features less deterioration and more bending strength.
