Abstract
The present invention is for providing a milling cutter which can provide for both an improvement in sharpness and a retention of cutting edge strength, while making the transverse cross-section an easily manufactured polygon shape. The milling cutter with a plurality of peripheral cutting edges (12) has a polygon shape transverse cross-section. The polygon is a convex polygon with one more apex point (13) existing between apex point pairs constituting the peripheral cutting edges with an apex angle greater than that of the apex points, and a longer side of the sides on either side of each of the peripheral cutting edges constitutes a rake face (14), while a shorter side constitutes a relief face (16).
