Abstract
The insert holder (24, 36) has spaced apart upper and lower jaws, with the upper jaw (38) resiliently rotatable relative to the lower jaw (40) about an angled pivot axis. The insert holder (24, 36) includes a forwardly disposed insert mounting portion (32, 36) that includes a forwardly projecting clamping finger (56) and a forwardly projecting support rib (58). The clamping recess (42) is partially defined by an elongated recessed hinge surface (52) formed on the angled hinge portion (50). The recessed hinge surface (52) includes first and second hinge ends (54A and 54B) that are longitudinally spaced from each other. The second hinge end (54B) is located forward of the first hinge end (54A).
