    摘要： An end mill for finishing the face or side of hard work comprising a shank (11), a plurality of helix cutting edges (10) on the periphery of the end mill, and a cutting edge section perpendicular to the axis of the end mill having a polygonal shape with three or more angles, the cutting edge being the edge formed at each vertex (12) of the polygonal shape along the axis of the end mill and being circumscribed by an imaginary cylinder, and the end mill being characterized in that the helix direction of the cutting edge is identical to the rotational direction of the end mill. The end mill of the disclosure is able to cut the face or side of the hard work at a feed rate several times higher than that of conventional end mills. Moreover, the end mill of the present invention assures superior surface roughness of finished work.
