Coated cutting tool

A method of making a coated cutting tool, the method comprising chemical vapor deposition of a coating on a substrate, wherein said coating includes an inner layer of TiN, a subsequent layer of TiCN and a Al2O3 layer located between the TICN layer and an outermost surface of the coated cutting tool, wherein the substrate is made of cemented carbide composed of hard constituents in a metallic binder and wherein the metallic binder includes 60 to 90 wt % Ni, wherein the TiN layer is deposited on the cemented carbide substrate in two subsequent steps at a temperature of about 850-900° C. and a pressure of about 300-600 mbar:

• a first TiN deposition of TiN-1, followed by a second TiN deposition of TiN-2, the TiN-1 deposition being performed in a gas having 1-1.5 vol % TiCl4 and H2 and N2, wherein the volume ratio H2/N2 is 0.05-0.18, and wherein the gas includes 0.5-1.5 vol % HCl, and the TiN-2 deposition is performed in a gas having 2-3 vol % TiCl4 and H2 and N2, wherein the volume ratio H2/N2 is 0.8-2.5.
