45° Lock Miter Router Bit

The interlocking fingers of our Lock Miter Router Bit provide a strong mechanical locking action that makes it much easier to clamp. There is no tendency for the joint to slide out of alignment under clamping pressure, and the wedged tenons tighten up nicely for a strong corner joint. The increased long grain gluing surface also helps to strengthen the joint over a basic rabbet or butt joint. To machine, run one part resting against the table, and the corresponding part vertically against the fence.
