  • Chip control insert
    Patent number: 5147159
    Abstract: Chip control insert having parallel face central aperture diamond configuration, cutting edges extending above a planar recess, annular and discrete corner island locating surfaces, each with radially outward pointed chip breaking projections extending from the annular locating surface toward the center of each cutting edge and from each of the islands toward its respective acute and obtuse corner. Islands at the acute corners are larger than islands at the obtuse corners.
    Type: Grant

  • Ceramic cutting insert
    Patent number: 4963061
    Abstract: In a ceramic indexable cutting insert, an edge strengthening land extends rearwardly of a beveled cutting edge at an angle of from about 80 to about 100 degrees with respect to the peripheral side surface, and a grooved recess extents rearwardly and along the edge strengthening land to direct chips upwardly and outwardly away from the insert and the cutting edge. In one embodiment of the present invention intended for conditions of heavy depth of cut, enhanced edge strength is sacrificed and an edge strengthened land is not provided.
