Fein Tool makes sanding heads for small places.
The tool is expensive, although it has come in very handy for many
situations.
I have not used it for sanding but cutting.
I do have an entire "head set" that fits the high speed machine that allows
for sanding "small" places.

I have been looking for something to do some sanding on the bottoms of the
holes and slots. Something to use with an electric drill to just smoothe the
bottoms a bit. I'm not coming up with anything, maybe yo all have some
ideas. Thanks.
