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 11deg relief ang., M class, square insert, without chipbreaker for finishing to medium cutting
For steels. Very tough grade for milling. Excellent thermal crack resistance. This grade also provides good wear and impact resistance
