Abstract:
1. A rotary cutter having an axis of rotation, comprising: a shank section extending along the axis of rotation; a fluted section extending along the axis of rotation, having a first end integrally attached to the shank section, a second end, and an outer surface; and a plurality of helical teeth disposed along the outer surface, including a first helical tooth having a first cutting edge with a first undulating geometry, and a second helical tooth having a second cutting edge with a second undulating geometry, wherein said plurality of helical teeth are arranged so that rotationally successive cutting edges are sufficiently dissimilar relative to one another to inhibit a detrimental periodic response in the rotary cutter, and wherein the first undulating geometry and the second undulating geometry are both non-periodic.
