Those bits occasionally come in handy. I didn't have a bit small enough and long enough to cut out this bear sign from the 1.5" thick blank, so I cut it as deep as I could with a 1/8" spiral bit and finished the cut on the band saw leaving about a 1/8" margin. Then I used one of the miniature bits with a bearing to finish the cut using the partially cut portion as the guide. Nice to have in your arsenal of bits when the need arises.
