US D601592 S1
The application relates to the design of a cutter bit. The cutter bit has a tapered, cylindrical cutting section which terminates in a point and has a skirt section tapering outward near its midpoint. The other end of the cutter bit is cylindrical with two areas of lesser diameter than the surrounding areas. In the area closer to the skirt section there is an encircling hollow cylinder with an opening defined by opposing square-shaped projecting sections.
The unique design and appearance of this device are illustrated in the drawings.
