Abstract: The present invention provides a more practical hard-coated cutting tool having improved cutting performance during finishing so as to obtain a better finished surface. Provided is a hard-coated cutting tool including a tool body (7) coated with a hard coating (4) and having a cutting edge (3) formed on a ridge line intersecting a flank face (1) and a rake face (2). In the hard-coated cutting tool, the thickness h1 of the hard coating (4) on the flank face (1) side and the thickness h2 of the hard coating (4) on the rake face (2) side near the cutting edge (3) satisfies conditions 8 μm≦h1≦30 μm and 0≦h2/h1≦0.5 in a cross-section perpendicular to the cutting edge (3) in a range equal to or less than 0.3 times the tool diameter in the axial direction from the tip of the tool.

Abstract: There is provided a diamond film for cutting-tools which has high toughness, excellent adhesiveness, high hardness, and in which tool service life is considerably improved in relation to cutting ultra-hard alloys and other very hard work materials. A diamond film for cutting-tools formed on a base material, in which at least one or more multilayered film layers [A] are included in which the layers are constituted by layering a film layer [α] having a film thickness of 1 μm or more and 15 μm or less and a film layer [β] having a film thickness of 1 μm or more and 20 μm or less so that the film layer [α] is disposed on the base material side and the film layer [β] is disposed on the surface layer side; the film thickness of the entire film body is set to 4 μm or more and 30 μm or less; and the film layer [α] and the film layer [β] have predetermined film compositions.
