As one of the experienced ceramic inserts manufacturers, JoyJet offers ceramic inserts excel in high-speed machining and dry cutting of superalloys and hardened steels with exceptional heat resistance, minimizing tool wear while maximizing productivity. Made from ceramic materials (such as alumina or silicon nitride), their hardness is second only to diamond and CBN. They are primarily used in machining high-hardness materials such as hardened steel, cast iron, and high-temperature alloys.
