  • Patent number: 4176499
    Abstract: The disclosure relates to a simple drill sharpener for sharpening cutting points of twist drills; the sharpener having a drill guide and holder adapted to hold a drill in certain axial alignment and having means for engaging the trailing edge of one flute of a drill in cooperation with an abutment means which supports the shank end of the drill such that when one facet of the drill point is ground on a grinding wheel, torque is imparted to the drill and forcing it in a rotary direction to maintain it in firm engagement with said flute edge engaging means and with said abutment means, thereby precisely maintaining longitudinal axial position of the drill, and fixing the drill against rotation relative to the holder.
