Abstract: A hole placement guide adapted for marking and/or drilling hole locations at chosen positions in workpieces, and an elongated extension member for attaching to the hole placement guide in numerous positions, such that hole positions interior to the workpiece surface which cannot otherwise be accessed by the present hole placement guide can be marked and/or drilled, are described. The guide includes a marker and/or drill bit guide adapted to slide in a rotatable slot which permits all locations within a circle defined by the rotatable slot to be marked and/or drilled. In use, the present hole placement guide may be positioned at the corner of a drawer or door and the marker and/or drill guide adjusted in the slot to a desired hole position to be marked and/or drilled. The chosen location may then be transferred to other drawers and doors, as examples of workpieces, by positioning the hole placement guide at the same corner of another drawer or door.
