ABSTRACT:
A tool holder for clamping an insert in an insert receiving pocket of the tool holder wherein the pocket has at least a bottom wall and a side wall for engaging the sides of a cutting insert. A pin member with a head on one end for engaging the top of the insert is inserted through an aperture in the insert and the other or opposite end of the pin engages a hole formed in one of the bottom and side walls of the pocket. Threaded cooperating elements of cam means formed on the other end of the pin and in the hole in one rotated position engage and clamp the insert in the pocket and axial recesses in the threads of each are adapted to receive the threads of the other so as to allow free axial travel of the pin when it is in another rotated position.
