Abstract

In an end mill in which a tip portion of a tool body includes three or more odd number of gashes to define three or more odd number of end cutting edges, during cutting by rotating the tool body at high speed, occurrence of chattering vibration in the tool body is prevented to enhance surface finish of a workpiece and chip dischargeability. In an end mill in which a tip portion of a tool body 10 includes three gashes 11a through 11c to define three end cutting edges 13a through 13c such that the end cutting edge 13a is configured to reach a rotation center o while the other end cutting edges 13b and 13c are configured not to reach the rotation center, the size of the gash provided corresponding to each of the end cutting edges is adjusted to cause a center of gravity of the tool body to approach a rotation axis L.
