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.

T1200A grade a general purpose grade that employs a substrate with an improved balance between fracture and wear resistance to deliver superior finished surfaces in a wide variety of cutting conditions
