I'm considering a chuck upgrade, but wonder if anyone has ever tried removing the existing QC bits from the adapters? I read in a thread that they were 'pressed on', so I would assume they could be cut off somehow, if someone figured out a way to do it precisely. Has anyone ever removed the bits from the collars? I ask, as I have a full set (the $399 set) and would hate to lose out on using the bits if I upgrade.
