ABSTRACT:
A tool holder includes a shank portion, a head portion that includes an insert pocket defined by a seat surface, a first or radial support sidewall and a second or axial support sidewall, and a spherical contact point protruding from one of the first and second support sidewalls. The spherical contact point minimizes a contact area between a cutting insert mounted in the insert pocket and one of the first and second support sidewalls of the insert pocket. In one embodiment, the radial support sidewall includes two spherical contact points, and the axial support sidewall includes one spherical contact point. The spherical contact point may be formed by inserting a rivet-like structure into an aperture formed in the support sidewalls of the pocket.
