HI All,
Valco sells the drill bits too--just put them in a pin vise
under tools: https://www.vici.com/tools/tools.php
if you're careful, high gauge disposable syringe needles can be used to
widen a hole
...and yes, their "ferrule removal kit" are just repackaged dental
reamers...
take care,
gerry

However, there are no part numbers for the multitude of ferrules that are needed for the different column IDs... sometime even needing a ferrule with two holes.
