Rockler Tenon-Lok Dovetail Drill Bit

Lock those chair joints with Tenon-Lok
out of 5
The high-speed steel Tenon-Lok cutter features spring-action blades that flare out at the base, creating a dovetail-shaped round mortise. The sharpened tapered steel wedge-ring then sits in the flared mortise, expanding the tenon as it gets driven into place. The resulting joint will never come apart, and is immune to weather related expansion and contraction. The Tenon-Lok system requires both a cutter (available in several sizes) and a matching wedge ring (sold in multi-packs). A setter guide is included with every cutter.
