Claims

[Claims for Utility Model Registration] Polygonal plate-shaped throw-away tips 3 are incorporated into the cylindrical tool body 1 at intervals in an even number of axial rows, so that the outer cutting edge ridge 4 of each tip is spaced apart. In the throw-away end mill, the outer cutting edge 4 of the throw-away tip 3 has a straight cutting edge 4a and a divided cutting edge 4b with a non-cutting recess 5 at the same axial position on the outer periphery. A throw-away end mill characterized by the fact that the two are arranged alternately.
