Tech Tips

It happens to everyone, a drill bit breaks and the business end is stuck inside the hole in your precious metal jewelry. If you can’t reach it, how will you get it out? Place the ring into common Pickling Solution. The drill bit will dissolve in about 15 minutes.

(Caution: do not put stones in Pickling Compound.)
