Zusammenfassung:An object of the present invention is to provide a radius end mill with which cutting marks are not apparent following a cutting process, with which glossy milled surfaces are obtained, and with which the amount of labor involved in a polishing process can be reduced. A radius end mill comprises an end cutting edge (1), a corner radius cutting edge (2) that is formed contiguous with a peripheral side of the end cutting edge (1), and a peripheral cutting edge (3) that is formed contiguous with the corner radius cutting edge (2). A corner radius wiper face (5) is provided running along the corner radius cutting edge (2) so as to be contiguous therewith. The corner radius wiper face (5) wipes a cut surface cut by said corner radius cutting edge (2).
