The disclosure relates to a method of manufacturing a cutting tool including the steps of: providing a cutting tool blank including a cutting edge, defined by a cross-sectional wedge angle (&#x3b2;). The wedge angle has a variation along the cutting edge, and material is removed from the cutting edge with a constant material removal rate per length unit of the edge, such as to form a corresponding variation of edge rounding along the cutting edge. The disclosure further relates to a cutting tool including the cutting edge defined by the cross-sectional wedge angle having a variation along the cutting edge and wherein the cutting edge has a corresponding variation of edge rounding along the cutting edge.

Method of manufacturing a cutting tool and a cutting tool

A coated cutting tool comprising substrate and a coating, wherein the coating comprises a layer of MTCVD TiCN, and a layer of &#x3b1;-AlO, wherein the &#x3b1;-AlOlayer exhibits an X-ray diffraction pattern, as measured using CuK&#x3b1; radiation, the (hkl) reflections used are (012), (104), (110), (113), (116), (300), (214) and (0 0 12), and the TC(0 0 12) is higher than 5 and a full width half maximum (FWHM) of a rocking curve peak of the (0 0 12) plane of the &#x3b1;-AlOis lower than 30&#xb0;.
