摘要： A device for aligning a hand-held electric drill to a vertical position with respect to a flat workpiece includes a disc-shaped circular housing having a centered axis, upper and lower faces, and a channel centered on the axis in communication with both faces. A gripping feature associated with the channel permits removable attachment of the housing to a rotating component of the drill, such as the drill shaft or drill bit. A light-emitting component within the housing directs a narrow beam of visible light downwardly from the lower face. When the drill is vertically aligned, the beam of light produces a circular path on the workpiece.
