It has to be me. I'm about to replace three collets on Fein, Bosch and
Makita routers. I don't think I am over tightening them, but what else
could it be? I have soaked them in that green stuff, to no avail. Is
there anything I can do to restore them. (Even though I think it
obvious, I should spell out the problem with the collets is that I can't
remove the bits without a drift and hammer, and yes I do try rappin the
nut.) Thanks in advance.
