Rockler's new corner key doweling jig clamps to the corner of a box and guides an extended-length bit through the joint at a 45-degree angle. Adjustable to work with different thicknesses of stock and to allow fine-tuning of the hole position, the jig includes interchangeable 1/8-, 1/4-, and 3/8-inch diameter drilling guides. Once set, the jig can be moved and reclamped to drill a series of matching holes. As part of the product rollout, Rockler is also offering a free downloadable plan for a kitchen knife block that incorporates a decorative corner dowel pattern created with the jig.
