Patent ID: 8827602

Claim:
A cutting insert comprising: a lower face, adapted to be installed against a bottom of a pocket forming part of a tool holder, an opposing upper face having a front edge region that constitutes a rake face for chips produced by an associated front cutting edge, a rear side, for alignment of the cutting insert in a mounting position against a rear wall of said pocket, wherein a pair of surfaces disposed on a common protrusion extends from said upper face, said pair of surfaces comprising an abutment surface for driving the insert by a traveling member of the tool holder to the mounting position and, forwardly thereof, a deflecting surface for deflecting the path of chips away from a direction running from a rear edge of the rake face to said abutment surface for driving the insert to the mounting position, wherein said common protrusion has a lateral profile which exhibits said pair of surfaces at least at one of a plurality of annular segments, thereby forming, overall, a ridge line defining a crater having an inner side exhibiting a plurality of abutment surfaces for driving the insert to the mounting position and having an outer side exhibiting a plurality of deflecting surfaces.
