ABSTRACT:
A single-toothed ball end mill provided with a cutting edge including a starting end, positioned near the center of rotation of the end mill and having an upright portion. The cutting edge is defined by a line curved outwardly in the direction of rotation of the end mill when viewed from the bottom. The cutting edge has its greatest curvature at the center portion of the end mill so as to permit the cutting edge to initiate a cutting operation with its starting end and to thereafter perform the cutting operation progressively in a radially outwardly direction.
