ABSTRACT:
In an insert holder for indexable cutting inserts, a clamping device is located which includes an L-shaped member having first and second arms. The first arm is received in a blind hole in the cutting insert and the second arm is actuated by a pressure screw. A free end portion of the second arm has a yoke received in a recessed annular waist portion of the screw so that movement of the screw causes the L-shaped member to rotate and push the insert downwardly against a base surface and laterally against an upright support surface. The insert has a central elevated plateau on its top side to enable a depth of the blind hole to be maximized.
