ABSTRACT:
An end mill10is a tool for milling a metal block such as a metal mold and is placed in a machine tool such as a milling machine when in use. The end mill10is used to provide a rotary milling cutter and a milling method using the same, in which it is possible to perform orthogonal milling and pocket milling to efficiently form four corners with small radius, without repeatedly milling using a small-diameter end mill. The end mill10has two cutting edges11aand11bat its distal portion, and an edge angle D1formed by the two cutting edges11aand11bis 70.53 degrees.
