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.

A cutting tool includes a body having a forward end and a rearward end. The forward end includes an insert-receiving pocket with a threaded hole having a center axis. The cutting tool further includes a cutting insert with a countersunk bore with a center axis. The cutting tool includes an error proofing feature for preventing the cutting insert to be properly mounted in an insert-receiving pocket when an offset distance between the center axis of the threaded hole of the insert-receiving pocket and the center axis of the countersunk bore of the cutting insert is greater than a predetermined percentage of the outer diameter of the threaded screw.
