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 () coated with a hard coating () and having a cutting edge () formed on a ridge line intersecting a flank face () and a rake face (). In the hard-coated cutting tool, the thickness hof the hard coating () on the flank face () side and the thickness hof the hard coating () on the rake face () side near the cutting edge () satisfies conditions 8 μm≦h≦30 μm and 0≦h/h≦0.5 in a cross-section perpendicular to the cutting edge () in a range equal to or less than 0.3 times the tool diameter in the axial direction from the tip of the tool.
