Abstract
A rotary cutting tool includes a support structure having a central hub located at an axially rearward end of the rotary cutting tool. A plurality of primary support members extends from the central hub in different axial and radial directions in three-dimensional space with respect to a central, rotational axis of the rotary cutting tool. The support structure may include one or more secondary support members extending from a primary support member in different axial and radial directions in three-dimensional space, and one or more tertiary support members to increase stiffness of the support structure. The central hub extends in a plane that is substantially perpendicular to the central, rotational axis of the rotary cutting tool. In one embodiment, each of the plurality of primary support members have a different physical dimension.
