ABSTRACT:
Round indexable cutting inserts are locked in fixed angular positions in the pockets of a milling cutter by conically tipped screws which seat in recesses formed in the back faces of the inserts. By turning the screws, their tips may be retracted to inactive positions to enable conventional polygonal inserts to be used in the pockets.
