    Abstract: The present invention relates to a coated cutting tool for chip forming machining of metals comprising a substrate having a surface coated with a chemical vapour deposition (CVD) coating. The coated cutting tool comprises a substrate coated with a coating comprising a layer of α-Αl 2 O 3 , wherein said α-Αl 2 O 3 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 comprises a MTCVD TiCN layer located between the substrate and the α-Αl 2 O 3 layer. The MTCVD TiCN layer exhibits a {211} 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%.
