In addition, this new coating is said to extend tool life and reduce flank wear on the insert by up to 200% compared to most conventional cutting tools.

According to the company, cermet is derived from an amalgam of ceramic and metal. It comprises a ceramic material based on titanium carbide or titanium carbo-nitride cemented with a metal binder whereby the ceramic provides the resistance to wear and the metal its toughness. Cermets have a low affinity with iron which enables a high level of “as-machined” surface finish, the supplier says.
