Abstract
A cutting insert is formed with a central planar support face, at least three cutting edges spaced outwardly from and around the support face and forming corners, and a land extending along each cutting edge between the respective corners and projecting from the respective cutting edge inward toward the support face. The land has a central region of a relatively great width measured perpendicular to the respective cutting edge and a pair of side regions flanking the central region and each of a relatively narrow width. The great width is equal to between 1.5 and 4 times the narrow width, and the land forms with a plane of the support face an outwardly open negative land angle of at least 0°.
