Cermet is a cutting material combining ceramics and metals (usualט Nickel). The result is a harder substrate than carbide, therefore more wear-resistant, and enables machining at higher cutting speeds. The downside is very low toughness, and therefore, it is used only for finishing applications in stable conditions. Some tougher versions are available today for semi roughing. Used very often in Duplex milling.
Positive 7deg relief ang., M class, 55deg rhombic insert, for finishing
New coated cermet grade. GT9530 offers longer tool life in high speed machining.
