Hmmm, I've never had tool slippage with R8 end mill
holders. I HAVE had slippage on a few occasions using
collets in the R8. So, except in unusual circumstances, I
ALWAYS put end mills in an R8 holder, instead of a collet.
When it did slip, I'm pretty sure I didn't tighten the
collet enough, or maybe there was a little chip in there
that crushed out, loosening the collet.
