CVD coated cutting tool

A coated cutting tool comprising:

• a substrate coated with a coating including a layer of α-Al2)3, wherein a thickness of the α-Al2O3 layer is 2-4 μm and wherein said α-Al2O3 layer exhibits a texture coefficient TC(hkl), as measured by X-ray diffraction using CuKa radiation and θ-2θscan, defined according to Harris formula

• where I(hkl) is the measured intensity (integrated area) of the (hkl) reflection, I0(hkl) is the standard intensity according to ICDD's PDF-card No. 00-010-0173, n is the number of reflections used in the calculation, and where the (hkl) reflections used are (1 0 4), (1 1 0), (1 1 3), (0 2 4), (1 1 6), (2 1 4), (3 0 0) and (0 0 12),
• wherein TC(0 0 12) ≥7.2, and wherein the ratio of I(0 0 12)/I(0 1 14) ≤0.8, and wherein said coating further includes a MTCVD TiCN layer located between the substrate and the α-Al2O3 layer, wherein the thickness of said MTCVD TiCN layer is 2-3 μm and wherein said MTCVD TiCN layer exhibits a {211} pole figure as measured by EBSD in a portion of the MTCVD TiCN layer parallel to an outer surface of the coating and less than 1 μm from an outer surface of the MTCVD TiCN, wherein a pole plot based on the data of the pole figure, with a bin size of 0.25° over a tilt angle range of 0°≤β≤45° from the normal of the outer surface of the coating shows a ratio of intensity within β≤15° tilt angle to the intensity within 0°≤β≤45° of ≥45%.
