Abstract: A coated cutting tool for chip forming machining of metals includes a substrate having a surface coated with a chemical vapour deposition (CVD) coating. The substrate is coated with a coating having a layer of α-Al2O3, wherein the α-Al2O3 layer exhibits a texture coefficient TC(0 0 12)≥7.2 and wherein the ratio of I(0 0 12)/I(0 1 14)≥0.8. The coating further includes a MTCVD TiCN layer located between the substrate and the α-Al2O3 layer. The MTCVD TiCN layer exhibits a pole figure, as measured by EBSD, in a portion of the MTCVD TiCN layer parallel to the outer surface of the coating and less than 1 μm from the 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%.

Abstract: A coated cutting tool includes a substrate and a coating. The coating has an α-Al2O3-multilayer of alternating sublayers of α-Al2O3 and sublayers of TiCO, TiCNO, AlTiCO or AlTiCNO. The α-Al2O3-multilayer includes at least 5 sublayers of α-Al2O3, wherein the total thickness of the α-Al2O3-multilayer is 1-15 μm and wherein a period in the α-Al2O3-multilayer is 50-900 nm. The α-Al2O3-multilayer exhibits an XRD diffraction over a θ-2θ scan of 20°-140°, wherein the relation of the intensity of the 0 0 12 diffraction peak (peak area), I(0 0 12), to the intensities of the 1 1 3 diffraction peak (peak area), I(1 1 3), the 1 1 6 diffraction peak (peak area), I(1 1 6), and the 0 2 4 diffraction peak (peak area), I(0 2 4), is I(0 0 12)/I(1 1 3)>1, I(0 0 12)/I(1 1 6)>1 and I(0 0 12)/I(0 2 4)>1.
