If you are making projects that require holes in glass, rocks or ceramic, you’ll need our 1/8″ Diamond Core Drill Bits. They work marvelously with our beveled clear glass panes or with stained glass. Use water as a coolant.
For use in a drill press. Will not work with a Dremel or flex shaft tool because the shaft is too big to fit.
1/4″ Shank, 1/8″ Hole – Set of two.
