Abstract: An indexable, invertable cutting insert has radially-oriented positioning segments on a front face of the insert and radially-oriented positioning segments on the back face of the insert. The radially-oriented positioning segments are shifted on the front face relative to those on the back face such that, when the cutting insert is engaged within the toolholder, the cutting segment utilized on the front face will never be directly opposite the cutting segment utilized on the back face. A toolholder system is made up of the cutting insert and a toolholder capable of securing and indexing the cutting insert.

Abstract: A round cutting insert with a reverse anti-rotation feature that can be manufactured easily and inexpensively is disclosed. The round cutting insert includes a plurality of dimples formed on a first surface and another plurality of dimples formed on a second, opposing surface. The round insert is reversible and indexable. The round cutting insert is removable received in an insert receiving pocket in a tool body. The insert receiving pocket includes a single projection that is capable of being received in one of the plurality of dimples. The cooperation between the projection and one of the plurality of dimples prevents rotation of the round cutting insert when mounted in the insert receiving pocket. The plurality of dimples and the projection can be any desirable complimentary shape, such as a slot, a V-shape, a wagon wheel, a sports wheel, a pyramid, and the like.

The round cutting insert is reversible and indexable. The round cutting insert is removably received in an insert receiving pocket in a tool body wherein the insert receiving pocket includes a plurality of dimples for receiving one of the plurality of first projections or the plurality of second projections. This arrangement prevents rotation of the round cutting insert while mounted in the insert receiving pocket.

Abstract: A combination of a cutting insert and a shim. The cutting insert and shim have two opposing end surfaces with two identical opposing major side surfaces and two identical opposing minor side surfaces extending between the minor side surfaces. Each end surface of the insert has two lowered abutment members, each having a shim abutment surface for contacting the shim. One end surface of the shim has two raised abutment members, each having an insert abutment surface for contacting the insert. The abutment surfaces contact each other in an area where high cutting forces occur so as to help distribute the loads encountered in the cutting operation, as well as provide protection of the insert pocket in case of insert failure.
