    Abstract: A cutting tool insert has a cermet body with a Co and/or Ni binder phase and a coating deposited as monolayer or as multiple and/or alternating layers of carbide, nitride or oxide. The coating has a thickness of 21-50 μm, when the inserts have a flat rake face, without or with simple chipbreakers and a Co binder phase, or has a thickness of 10-50 μm, when the inserts have a rake face land with a width of 100-300 μm with an angle of 10-25° to the rake face and a Co and/or Ni binder phase. The cermet body has more than 50 vol. % Ti-based carbonitride and less than 15 wt % and more than 6 wt % Co and/or Ni binder phase and a hardness of >1650 HV3. The disclosure also relates to the use of the coated cutting tool insert for the machining of cast iron work pieces.
