A surface-coated cutting tool includes a substrate composed of cemented carbide and a coating film. The coating film includes an intermediate layer in contact with the substrate and an upper layer formed on the intermediate layer. The upper layer is made up of a single layer consisting of an upper base layer which is a layer in contact with the intermediate layer or multiple layers constituted of two or more layers. A mismatch in lattice interplanar spacing in an interface region between the substrate and the intermediate layer is not higher than 65% of a theoretical value of a mismatch in lattice interplanar spacing between the substrate and the upper base layer. A mismatch in lattice interplanar spacing in an interface region between the intermediate layer and the upper base layer is not higher than 65% of the theoretical value of the mismatch in lattice interplanar spacing between the substrate and the upper base layer.

A method for producing a cutting tool including a tool body including a hard coating, the method comprising: applying the hard coating to the tool body at least in an area of a cutting edge, a flank, and a chipping surface; depositing the hard coating on a surface of the tool body, of the cutting tool in an area of the cutting edge, of the flank adjacent to the cutting edge, and of the chipping surface adjacent to the cutting edge; sharpening the cutting edge that is provided with the hard coating and that forms a dull rounded edge by partially removing the hard coating in the area of the flank of the cutting edge by laser machining to form a sharpened cutting edge so that an angle is enclosed between a first geometric plane in which a surface of the tool body extends.
