A titanium-based carbonitride grade for finishing and semi-finishing turning operations with excellent properties is obtained starting from a titanium-based carbonitride grade used for milling operations. The carbon content of a conventional titanium-based carbonitride grade used for milling operations is optimized in such a way that it is close to the point where eta -phase or other substoichiometric phases are formed. The improved titanium-based carbonitride is also provided with a thin wear resistant Ti-containing coating deposited preferably by PVD technique.
