ドミル。[Scope of claim for utility model registration] A flute groove 3 provided at the tip of the tool body 1,
4 is a throw-away type end mill in which a first series of throw-away tips 5 and a second series of throw-away tips 6 and 7 in a spaced relationship are provided, wherein the throw-away tips of the first series are 5 has a diamond-shaped plate shape, and its outer peripheral cutting edge 12
extends in the axial direction, and its bottom edge 11a extends to the vicinity of the center of rotation with a relief angle θ, and the throw-away tip 6 belonging to the second series has a larger diameter than the throw-away tip 5. By forming small diamond-shaped plates having substantially similar shapes, an outer peripheral edge ridge 13 and a bottom edge ridge 11b that does not reach the vicinity of rotation are respectively formed, and the other throw-away tips 7 have approximately the same length as the throw-away tips 6. By making it into a parallelogram plate shape with the short side being,
A throw-away end mill characterized in that an outer peripheral cutting edge 14 on the long side extends and complements the outer peripheral cutting edge 12.
