Abstract
A cutting insert which includes a holder that contains a pocket and a hard insert that has a rake surface. The hard insert is contained within the pocket so as to present a cutting edge. The cutting insert also includes a chipbreaker which comprises a plate with a bottom surface. The chipbreaker is attached to the cutting insert (or optionally to the holder) so that the plate is spaced above the rake surface of the hard insert a first distance forming a conduit for passage of the chips away from the cutting insert. The conduit is defined at least in part by the rake surface of the cutting insert and the bottom surface of the chipbreaker plate.
