Dissolving broken drill bits can be quick and easy!
Using a mixture of 1 part Alum spice to 2 parts water. It works quickest if you heat the solution up(I use my studio crock pot). After about 30 minutes the drill bit should be completely gone! Alum is a spice commonly found in grocery stores. The great thing about using alum is that it is natural and safe. Something you can use to spice up your food as well as create jewelry? That's a no brainer to me.
