A cutting tool insert for machining by chip removal includes a body of a hard alloy of cemented carbide, cermet, ceramics, polycrystalline diamond or cubic boron nitride based materials onto which a hard and wear resistant coating is deposited by physical vapour deposition (PVD). The coating includes at least one layer of a NaCl-structured (TiAlCrMe)(CON) where Me is one or more of the elements Zr, Hf, V, Nb, Ta, Mo, W and/or Si, 0.10&#x3c;a&#x3c;0.60, b+d&#x3e;0.20, c&#x3e;0.05, 0&#x2266;d&#x3c;0.25, 0.75&#x3c;x&#x3c;1.05, 0&#x2266;y&#x3c;0.25 and 0&#x2266;z&#x2266;0.25 with a thickness between 0.5 and 10 &#x3bc;m. The layer has a columnar mictrostructure with an average columnar width of &#x3c;1 &#x3bc;m, a compressive stress level of &#x2212;6 GPa&#x3c;&#x3c3;&#x3c;&#x2212;0.5 GPa and a nanohardness &#x3e;25 GPa.
