For indexable inserts that need to deliver extra-long tool life and top surfaces for turning applications on steel, iron or cast materials, we use cermet.
Cermet is a composite material. Its base consists of ceramic and several metals, with cobalt acting as the binder. What characterises indexable inserts made of cermet is that they are hard and low-wear. In practice, this means high stability and impressive precision. You should always use cermet indexable inserts on the machine if you are cutting materials that tend to stick - for example steels, stainless steels, cast iron and iron.
Cermet is a great cutting material for cutting tools. We do everything we can to ensure that its outstanding properties are fully utilised during roughing, finishing and grooving.
