1. A rotary cutting tool, comprising:
a disc-like central body having an outer peripheral surface;
a peripheral support member extending circumferentially along the peripheral outer surface of the disc-like central body, the peripheral support member providing support against centrifugal and cutting forces exerted on an insert pocket during a cutting operation; and
a radial support member extending radially along the disc-like central body to the peripheral support member,
wherein the radial support member structurally interacts with the peripheral support member to provide additional support for the insert pocket against centrifugal and cutting forces exerted on the insert pocket during a cutting operation,
wherein the radial support member and the peripheral support member have a three-dimensional topology.
