Abstract
Cutting inserts are assembled around the periphery of a holder of a tool by respective fastening screws. Each insert is seated against a support surface, and its respective fastening screw passes through a center hole in the insert and is threaded into a mounting hole formed in the support surface. The mounting hole is oriented non-perpendicularly to the support surface, whereby the fastening screw forms an angle with the axis of the insert's through-hole and is more accessible to a screwdriver. The through-hole has a conical or spherical portion which supports a spherical head of the fastening screw.
