  • Patent number: 6637989
    Abstract: A centering feature (230) on a drill bit (110) configured without a pointed tip, formed as an opening (230) between first (206) and second (208) relatively angularly inclined portions of a work engaging end (116) of the drill bit (110). The first portion (206) of the work engaging end (116) is defined by a cutting edge (134), and the second portion (208) is defined by an end face side boundary (216) transversely aligned with the cutting edge (134). The cutting edge (134) and end face side boundary (216) are offset from each other to create the opening (230), which permits the drill operator to view a punch mark or other indication on the work piece where the center (232) of the intended hole is to be located. The drill operator positions the medial termination point (212) of the cutting edge (134) of the drill bit (110) over the center hole location (232) preparatory to contacting the drill bit (110) against the work piece to cut the hole.
