ABSTRACT:
A ball nose cutter having a replaceable single cutter insert in which the cutting edges thereof include a pair of mutually spaced apart cutting tips, one cutting tip at a time being selected for use by being located at the centerline of rotation of the ball nose cutter. The cutter insert is of circular cross-section for rotatably seating within a circularly cross-sectioned groove in a cutter body. A bore in the cutter insert is aligned with an off-axis threaded bore in the cutter body so that a holder screw which passes therethrough threadably holds the cutter insert with respect to the cutter body. A planar face is provided adjacent each cutting edge, wherein each planar face has an orientation so that the selected cutting tip is exactly located on the centerline rotation of the ball nose cutter.
