Our Corner Key Doweling Jig lets you join mitered corners by running dowels through the joint at 45°. The exposed oval dowel ends result in a unique decorative effect, and the dowels serve to strengthen the joint, much like splines. You can use solid wood dowels in a contrasting species, non-ferrous metal tubes, a combination of both, or even tie the joint together with leather laces. More advanced decorative effects can be achieved by double-drilling to create dowels with a multi-layered core. The jig makes the angled drilling accurate and easy. No other product on the market offers the same functionality, repeatability and convenience.
