Title: Flat beaded double end track bit

Abstract: The improved flat beaded track bit disclosed herein comprises an elongated, generally rectangular member having first and second ends separated by a middle section. First and second drill bodies are formed on the first and second ends, respectively, of the member, with the drill bodies being identical, but mirror images of each other. The lands of the first and second drill bodies terminate adjacent to the middle section of the member, and the diameters of the lands of the drill bodies are larger adjacent to the first and second ends of the member than adjacent to the middle section of the member.
