ABSTRACT:
An improved cutting tool has general utility, but is particularly adapted for use as a profile-style cutter, or as a form-relieved cutter. The cutting tool includes a body provided with a plurality of slots spaced circumferentially thereabout, a blade arranged in each slot, and a wedge inserted axially into each slot to securely mount the blade on the body. Each blade is provided with a pair of axially-spaced locating shoulders extending rearwardly from its trailing surface, and adapted to embrace the side faces of the body to prevent axial movement of the blade relative to the body. The wedge has a retaining lug extending forwardly beyond its leading surface, and adapted to be slidably inserted into a retaining groove provided in the body. The wedges and blades have cooperative compound tapered surfaces which are adapted to engage one another to cause the blade to seat against the slot base and trailing surfaces, and to prevent radial movement of the blade relative to the body. The invention also provides an improved process of fabricating a rotary cutting tool of the inserted blade type.
