Lots of guys don't use 'em. My BP didn't have one when I got it, but
I replaced it.

I recently bought a used rockwell mill. There is no drive pin in the
spindle that is suppose to engage with the R8 collet. My other mills
do have drive pins. Is this a problem that I need to fix??
I seem to remember this question before and it might be ok??
