Claims

[Scope of utility model registration request]

A concave portion is formed in a plate-shaped polygonal tip having a bottom blade or a bottom blade and a peripheral blade in a side direction from the plane of the tip at a position including the axial center portion of the body when the tip is fixed to the shank body. The milling tool is characterized in that the recess is configured with a depression ratio of at least two or more, and a ridgeline formed by the recess, the side surface, and the plane serves as a cutting edge for cutting the center of rotation of the tool.
