The Corner Key Doweling Jig from Rockler lets you reinforce mitered corners by running dowels through them at 45°. The exposed ends of the dowels produce a unique decorative oval effect, and the dowels serve to strengthen the joint, much like splines. You can use solid wood dowels in a contrasting species, nonferrous metal tubes, a combination of both, or even tie the joint together with leather laces. Or, consider double-drilling the joints to create dowels with a multi-layered core. The jig makes the angled drilling procedure accurate and easy. No other product on the market offers the same functionality, repeatability and convenience.
The jig can be quickly and easily calibrated for drilling through 1/4-, 3/8-, 1/2-, 5/8- or 3/4-in.-thick workpieces. Once set, you can move and re-clamp the jig to drill the next hole (clamps are sold separately). Precisely molded reference lines and a clear alignment window enable fast and accurate setups. Included with the jig are interchangeable 1/8-, 1/4- and 3/8-in. steel drill guide assemblies and a case with room for extended-length drill bits (sold separately).
Rockler’s Corner Key Doweling Jig (item 59517) sells for $39.99.
