Geof,
Don't you just hate that?
FWIW, if you want additional security without grinding flats on the shank, you can also loctite the tool into the holder. You'll have to unscrew the pullstud to press the tool out of the holder, not that loctite gets all that much of a grip on the smooth bore and smooth tool shank, but it will help the setscrew hold the tool.
First you get good, then you get fast. Then grouchiness sets in.
