ABSTRACT:
A rotary cutting tool having a mounting portion with a plurality of mounting sections, each having a radially aligned pocket to receive a cutting insert. There is a positioning and actuating assembly by which a related wedge block can be positioned in its related pocket in wedging engagement with its cutter insert. The side walls of each pocket converge in a radially outward direction so that centrifugal force of the rotating causes the wedge blocks and the cutters to come into a firmer wedging engagement. The positioning and holding assembly can be moved from its retaining position to permit individual cutting inserts to be moved or replaced. A center bolt assembly moves a central portion of the positioning and holding assembly vertically so as to cause retaining arms to move into and out of retaining engagement with related wedge blocks.
