Cermet is a composite material made of ceramic and metal. A cermet insert is a cutting insert that is made of this composite material. It is a type of tool that is used for cutting and machining operations in a wide range of industries such as aerospace, automotive, energy, and medical.
Cermet inserts have a high resistance to wear and can maintain their sharpness for a long period of time. They are suitable for machining hard and abrasive materials, such as cast iron, heat-resistant alloys and some of the superalloys. They are also suitable for high-speed machining and can withstand high cutting temperatures.
Cermet inserts have a combination of hardness and toughness, which makes them a good choice for machining operations that require both high cutting speeds and high cutting forces. They are also suitable for roughing, semi-finishing and finishing operations.
Cermet inserts come in a variety of shapes and geometries, including round, square, and triangular, and can be used for a variety of machining operations including turning, milling, drilling, and boring.
In conclusion, cermet inserts are a type of cutting tool that is made of a composite material and are suitable for machining hard and abrasive materials and operations that require high cutting speeds and high cutting forces. They offer a balance of hardness and toughness and are suitable for a variety of machining operations.
