Providing an information deals with the application of Ceramic Metal (Cermet) as a cutting tool applied for hard machining of steel is the objective of this review paper. Cermet is made of hard metals and was introduced just after the invention of Cemented Carbide. As a cutting tool, the conventional Cermet was known as TiC-based Cermet. Unfortunately, it was not as successful as Cemented Carbide due to its brittleness of low fracture toughness of TiC substrate. Thanks to TiN material. The addition of TiN improved the fracture toughness, and the modern era of Cermet was begun. A TiCN-based modern Cermet is characterized microstructurally by a structured hard phase featuring core-rim structure embedded in a tough Co-Ni binder. The effort to refine the fracture toughness of TiCN Cermet is discussed in this paper including the effort to raise its performance through coating technologies. In particular, its performance which is given in term of productivity and represented by volume of removal rate (VMR) is discussed. Finally, conclusions and recommendation for future works are written.
