<p>The disclosed cutting tool, which cuts a metal die while rotating, has a cutting edge (136) disposed on the axis of rotation (250). The angle (?) between a region (136d) corresponding to the end edge of the cutting edge (136) and a plane perpendicular to the axis of rotation (250) satisfies relation (1). (1) -0.9° = ? = +0.9°</p> |
