ABSTRACT:
A router bit with a position stop is disclosed. The router bit includes a body with a collar extending outwardly from it and a shaft extending outwardly from the collar. At least one cutter blade is mounted to the body and the cutter blade may be used to cut a profile into a workpiece. The collar has a first diameter, the shaft has a second diameter and the first diameter is larger than the second diameter. The collar has a face formed a spaced distance or height from the transition point between the collar and the body. The face rests against the upper surface of a chuck when the shaft is secured in the chuck. This allows the body and hence the cutter blades to be held a predetermined distance above the upper surface of the chuck. A second router bit may be provided to cut a complimentary second profile in a second workpiece. The second router bit includes a collar that positions the cutter blade of the second router bit in the chuck at a complimentary height with respect to the cutter blade of the first router bit. When the first and second workpieces are brought together, the profiles of the two workpieces are able to interlock in such a way that the workpieces are both functionally and aesthetically aligned with each other.
