ABSTRACT:
A center or non-center cutting end mill for orbital drilling includes a shank having a shank diameter; a neck having a neck diameter; a cutting head having a cutting diameter; a corner radius; a dish angle; and a longitudinal axis, the cutting head including a forward cutting end having a convexly curved section located between the longitudinal axis and the corner radius, wherein the convexly curved section causes material removed from a workpiece to flow radially outward from an initial contact area toward the corner radius, thereby minimizing the accumulation of material in a central portion of the forward cutting end.
