I got a tiny bit of drill bit broken off in a tiny pilot hole I was
hand drilling. It’s stuck in there really hard. It’s only a little
fragment. Attempts to continue drilling in the hopes that it would
loosen means the drill is now working next to the broken bit. If I
continue the hole will be too large. The hole is too small to get
anything in thereto get a grip on the fragment.
This is a finished piece of jewelry, a customer’s repair, and I just
wanted to wire on a bail to replace a soldered one that broke off.
There is a stone only about 2 mm under where the hole was supposed
to come out. It is an open backed bezel set stone, stepped bezel,
set really high. Therefore there is room to fit a wire in, under the
rim, I “just” needed to be careful with drilling so I wouldn’t hit
It was two bezel set citrines (or they might be lemon quartz, I
forget). So taking out the stones is not where I want to go. Is it
possible to use alum with faceted non-porous stones?
Brad Smith kindly suggested soaking it in alum and water to dissolve
the steel, but I don’t know if this is safe for stones. A google
search turned up one statement that it wasn’t. Is this true of all
