Abstract: The cutter assembly contains an axle having a number of parallel, equally spaced troughs along the axial direction, and a number of circular blade discs, each having a center hole threaded through by the axle. Each blade disc has a number of teeth along the circumference of the center hole corresponding and matching to the troughs of the axle. The blade disc has fewer blades than the teeth and the blade discs therefore can be mounted on the axle in different orientations so that their blades are spirally arranged. The axle of the cutter assembly has a fixed end and the blade discs can be sequentially installed to or removed from the other free end. The bearing at the free end has a smaller diameter so that the blade discs can be removed or installed directly passing through the bearing without removing it first.

Abstract: A tire rasp blade made with an arcuate shape having a planar body with cutting teeth at the outer working edge. The cutting teeth extend laterally relative to the planar body in alternating sets of curved sections. The curved sections preferably form a sinusoidal curve along the outer working edge. The tire rasp blade is made by initially forming an arcuate blade of planar material that has an outer periphery of varying radii from a center point of the arcuate blade; then cutting teeth are formed at the varying radii of the working edge of the planar material; and then an outer portion of the planar material is deformed laterally in opposite directions to form alternating, oppositely curved sections, with the cutting teeth all lying approximately at the same circumferential radius so that they all contact the tire to be buffed.

Abstract: A rasp blade 200 has cutting teeth 130, 132, 134, 136, 140 arranged along the outer perimeter of the blade and having a variable radius. The radius is raised for the teeth 130, 132, 134, 136 at either end of the blade. The radius is lower for the teeth 140 at the center of the blade 200.
