Cutting tool with integrated abrasive trimming elements

Abstract

An integrated cutting and trimming tool including a cutter tool body having, in one embodiment, a plurality of spaced-apart cutting elements on its cutting face, channel extensions extending between the spaced-apart cutting elements and abrasive coated radially projecting trimming elements. The abrasive coated radially projecting trimming elements are sized and shaped to fit within the confines of the channel extensions and can be fixedly or removably secured to the cutter body. The abrasive coated radially projecting trimming elements may be attached to a ring-shaped body to allow for unitary attachment to the cutter body. The integrated cutting and trimming tool may be adapted for edge cutting and trimming and overcomes the necessity of having two machines and processes to accomplish the cutting and trimming of materials by condensing the manufacturing process into one step.
