23. A router bit kit for use with a rotary cutting tool and comprising:
a first router bit having:
a first cutter blade adapted to cut a first profile in a first workpiece;
a first position stop disposed a first distance from the first cutter blade; said first position stop being adapted to abut an outer surface of a chuck of the rotary tool when the first router bit is engaged therewith and to thereby hold the first cutter blade the first distance away from the outer surface of the chuck;

a second router bit having:
a second cutter blade adapted to cut a second profile in the second workpiece; whereby said second profile is complementary to the first profile in the first workpiece;
a second position stop disposed a second distance from the second cutter blade; said second position stop being adapted to abut the outer surface of the chuck when the second router bit is engaged therewith and to thereby hold the second cutter blade the second distance away from the outer surface of the chuck; whereby an outer surface of the first workpiece is aligned with an outer surface of the second workpiece when the first and second profiles on the first and second workpieces are butted together.
24. The router bit kit as defined in claim 23 wherein the first router bit further includes a continuous first chip channel that runs alongside the first cutter blade and terminates at a chuck-engaging surface of the first position stop.
25. The router bit kit as defined in claim 23 wherein the second router bit further includes a continuous second chip channel that runs alongside the second cutter blade and terminates at a chuck-engaging surface of the second position stop.
