Choose from our money-saving sets and you'll be routing clean, precise ledges for a wide range of binding combinations. Carbide-tipped for long-life sharpness, the binding router bit has a 1/4" arbor to fit your shop router. 6-degree cutting edge downshear reduces grabbing on climb cuts, for cleaner results. The bit has an Allen screw with wrench for installing our custom depth-of-cut bearings. A special extension bushing for "stairstep" ledges keeps the bearing from rolling over dried glue squeeze-out, to prevent uneven cutting depth.
