A coated cutting tool includes a rake face, a flank face, and a cutting edge region between and adjoining the flank face and the rake face in a nose area of a cutting tool insert. The cutting edge region is intersected by an edge line and defines a cutting edge sector that defines an cutting edge radius, r. The coated cutting tool includes a substrate with a coating having a thickness between 1 μm and 40 μm, where the coating includes an α-AlOlayer and an MTCVD TiCN layer located between the substrate and the α-AlOlayer. The α-AlOlayer exhibits a texture coefficient TC(hkl), as measured by X-ray diffraction using CuKa radiation and θ-2θ scan, defined according to Harris formula where I(hkl) is the measured integrated area intensity of the (hkl) reflection with corresponding reference intensity I(hkl), and n is the number of reflections used in the calculation.
