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 cutting tool (2) is specified with a cutting region (4) that comprises a substrate (12) onto which a coating (10) is applied, which coating (10) is subsequently processed, whereby a sharp cutting edge (8) is formed. Furthermore, a corresponding method for the manufacture of the cutting tool (2) is specified. By means of the sharpening of the cutting edge (8) after the coating rather than before, a particularly sharp cutting edge (8) is formed, whereby the precision of the cutting tool (2) as well as its service life is improved.
