Kregrsquo;s Shelf Pin Jig with 5mm Bit allows fast and accurate drilling of shelf support holes in already assembled furniture or components before assembly. Supplied with a jig extender, connect two or more jigs together, or use the locating pin to insert through the first hole into an already drilled hole in order to continue a row of holes giving the ability to add more shelf positions. The hardened steel drill guides allow will allow many years of drilling before needing replacing. An adjustable fence attaches quickly to the front giving a reference edge to place against the front of the workpiece with the row of drill guides giving the shelf support holes either of two distances from the edge, 25mm or 50mm. The on-board storage means accessories and spares are always at hand, and with a place to store them they are never lost. The provided 5mm brad-point bit with depth collar cuts a clean hole without any tearout giving a well presented hole that can be proudly shown and not hidden.
