  • Patent number: 4222175
    Abstract: An alignment sight for hand drills utilizes a pair of sights, preferably a fixed tool, a unitary sheet, for mounting onto the exterior surface of an electrical hand tool of the hand drill variety. The sights are arranged so that the sight line extends perfectly parallel to the longitudinal axis located in the center of the chuck of the hand drill. In use, a user marks a spot on the work piece a fixed distance from the center of the hole to be drilled. Positioning the tip of the drill bit at the location of the hole, and locating the drill bit so that it extends substantially normal to the plane of the work piece, permits the user to maintain the sights aligned with the mark thereby forever maintaining the longitudinal axis of the drill bit perfectly normal to the surface of the work piece, providing thereby, a hole extending at right angles to the surface of the work piece.
