I was wondering if someone could tell me how I can expand the hole in
a bead. I have encountered several times now with stone beads where
the entry to the hole is nice and wide but once inside the hole
narrows considerably. Very frustrating. I know I can expand the
exterior of the hole using a bead reamer. But that hasn’t worked for
fixing the Narrow interior. Can I redrill the hole using a Dremel?
If so what type of drill bit should I use?
