General question: Can't the 5-C collet holding "spin indexer" be used
for sharpening the flutes of end mills?

Yes, occasionally. Do much more than that and the grinding swarf will find
its way into the unshielded mechanism, and you will be buying a new
indexer. A good friend of mine, excellent machinist, had this happen to
him so I know this is true. Maybe it might be possible to modify an
indexer with a plastic seal ring or something to help keep grinding grit
out, dunno.
