Abstract
An indexible insert is mounted on a shank. The insert includes angled centering surfaces which engage angled localizing surfaces on the shank. The insert includes abutment surfaces which engage support surfaces on the shank. The point of contact between the abutment and support surfaces is located farther from the working cutting edge than is the point of contact between the centering and localizing surfaces. Thus, when the working cutting edge is acted upon by a lateral force, the abutment and support surfaces bear against each other with a greater force than do the centering and localizing surfaces. Accordingly, less wear occurs at the centering surfaces.
