  • Cutter with positively locked round inserts
    Patent number: 5236288
    Abstract: Round indexable cutting inserts are locked in fixed angular positions in the pockets of a milling cutter by conically tipped screws which seat in recesses formed in the back faces of the inserts. By turning the screws, their tips may be retracted to inactive positions to enable conventional polygonal inserts to be used in the pockets.

  • Milling cutter capable of using indexable inserts of various shapes
    Patent number: 5145294
    Abstract: A milling cutter includes a generally cylindrical body whose outer periphery is formed with angularly spaced pockets capable of accepting indexable cutting inserts of various shapes such as octagonal inserts, square inserts or round inserts. The cutting face of each insert defines a single shallow frusto-conical surface in order to impart a gradual curvature to the cutting edges. This geometry, together with the geometrical location of the inserts in the body, enables the cutter to cut in an extremely free manner and with high efficiency.
