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.

Router bit with position stop

A cutter bit includes a body formed integrally with a mounting shank. The body defines a pair of chip boxes with two planar surfaces and a cutting knife mounted to one of the planar surfaces of each chip box. The body defines holes from the chip boxes to the outer surface of the body, said holes communicating with grooves formed along the outer surface of the body such that a continuous air passage is formed circumferentially around the body by each hole and respective groove. The air passages cool the cutter bit as well as quickly remove material chips from the cutting edge and workpiece. The rapid removal of the chips also allows a better view of the cutting edge and the workpiece. The lack of material in the holes and grooves reduces cutter bit weight, allowing use with smaller motors and reducing the loads associated with cutting operations.
