Abstract
A cutting insert includes a first mounting surface, a second mounting surface located on an opposite side of the insert from the first mounting surface, and a first side surface disposed between the first mounting surface and the second mounting surface. The insert further includes a first groove extending substantially diagonally across the first side surface and dividing the first side surface into discrete, separated, triangular first and second first side support surfaces. The first and second first side support surfaces are each bounded along first and second edges thereof by rake surfaces forming non-zero angles with the first and second side support surfaces and along third edges thereof by the groove.

A cutting insert, comprising:
- a first mounting surface;
- a second mounting surface on an opposite side of the insert from the first mounting surface;
- a first side surface between the first mounting surface and the second mounting surface;
- a second side surface between the first mounting surface and the second mounting surface and on an opposite side of the insert from the first side surface;
- a first end surface between the first mounting surface and the second mounting surface and between the first side surface and the second side surface;
- a second end surface between the first mounting surface and the second mounting surface and between the first side surface and the second side surface and on an opposite side of the insert from the first end surface, wherein the first end surface and the second end surface each comprises at least one clearance surface portion adjacent a corresponding cutting edge and at least one insert supporting surface portion remote from the corresponding cutting edge;
- and
- a first groove extending substantially diagonally across the first side surface and dividing the first side surface into discrete, separated, triangular first and second first side support surfaces, the first and second first side support surfaces each being bounded along first and second edges thereof by rake surfaces forming non-zero angles with the first and second side support surfaces and along third edges thereof by the first groove.
