ABSTRACT:
A rotary cutting devbice for cutting holes in a workpiece and a method of making a rotary cutting device. The method includes machining a notch across a face of a generally cylindrical body. The body has a longitudinally extending central axis and a central bore formed concentric therewith. Machining the notch forms at least one generally arcuate protrusion on a face of the body. A slot is formed through each of the protrusions resulting in two teeth being formed on either side of the mouth of the slots. A cutting tooth and a stabilizing tooth is formed on each side of the mouth of each slot formed in the body. The cutting tooth removes material from the workpiece and the stabilizing tooth limits the feed rate and prevents grabbing when a rotary motion is applied thereto.
