This invention relates to fixtures which aid in the drilling of holes for dowels and pegs. In particular, this invention relates to fixtures which aid the user in accurately positioning and guiding a drill or other boring tool into a workpiece and is of special utility in those situations in which the position of matched hole locations in adjoining or adjacent workpieces are critical. A drilling fixture is proposed which incorporates a body member and at least one perpendicular leg member wherein the leg member has a longitudinal stepped slot formed in it to receive a drill guide. The drill guide is fully adjustable along the length of the longitudinal stepped slot and may be locked in the desired location with a locking nut. The drill guide is an externally threaded cylindrical element with a flanged base and a longitudinal bore for receiving a drill bit. Alternatively, the longitudinal bore may include a counterbored end opposite the flanged end of the cylindrical element and be sized to accept drill bushings to provide use with a variety of sizes of drill bits.
