I'm looking for a router bit, sort of like like a flush trim bit
or a rabbeting bit, which would have an interchangeable
bearings to vary the depth of cut. Specifically I need to
have bearings larger than the diameter of the bit, so
that if the bearing rides on the pattern, the workpiece
would be trimmed proud of, rather than flush with,
the pattern. For "bonus points", I's like the cutter
to be a shear cutter versus a straight cutter, for
the cleanest cut.
I know I've seen this bit, but I can't find it on the
web. Can anyone point me in the right direction?
