摘要： A guide for cutting a mortise comprising a drill guide part (2) having a drill guide aperture (21) passing therethrough, the aperture (21) is composed of a plurality of overlapping cylindrical shapes (20) each of the same diameter and parallel cylindrical axis which define a common plane, the drill guide (2) is held in a clamp means (3) which has two clamp arms (4, 5) and (6, 7) one at each end, these are clamped to the work to be drilled and held in place thereon by means of plates (12, 13) and (14, 15) and screw threads (8 and 9), the clamp also includes two ridge parts (16 and 17) with guides (18) and (19) that have centering positions (27) included therein, the drill guide part (2) is contained between bridge parts (16 and 17) and can slide along the bridge parts (16 and 17) by one half a diameter of each shape (20), thus overlapping apertures can be drilled that will only leave an aperture with slight arcuately pointed parts which can then be easily removed.
