とを特徴とするエンドミル。[Claims for Utility Model Registration] A cross section perpendicular to the axis is a substantially regular polygon, and as it advances in the axis direction, the regular polygon forms an outer shape that turns around the axis. In an end mill in which the cutting edge is formed by a spiral ridgeline formed by each vertex of a regular polygon, the width of the opening is equal to the length of one side of the regular polygon.
1. An end mill characterized in that a groove-shaped chip former with a cross-sectional shape of 1/2 or less and a smoothly curved shape is provided in front of the cutting blade in the rotational cutting direction, close to and parallel to the cutting blade.
