I knew dremel made a six piece router bit set that i thought was only used in their plunge router attachment until I realized they made a router table/shaper attachment ($25 on Amazon). That got me looking for bits that could be used. Here is what I found
Amana Only some are 1/8" shank. Not many. But if you have a regular trim router then these are very nice.
The Proxxon set and the MLCS set seem to be the same. and have ten bits. I think one could get creative with these.
