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 ?-Al2O3, wherein the ?-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 ?-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 ?m 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°???45° from the normal of the outer surface of the coating shows a ratio of intensity within ??15° tilt angle to the intensity within 0°???45° of ?45%.
