Diamond Core Drill bits are perfect to drill out a hole in a shell, glass, gems or wood without chipping or cracking. Because it has a hollow core, it's easy to balance on a solid object and "core" it out. Please use these in water, to preserve the diamond bits and to keep the dust from being inhaled while drilling. We have 4 sizes: 1.5mm, 2mm, 3mm and 4mm 1.5mm is a store fave, and fits a 18 gauge jump ring. Great for delicate shells, and sunrise shells. 2mm sells well, and is Jamie’s fave, cause it fits a 16 gauge jump ring quite nicely and I love chunky jewelry. 3mm is Jason’s fave cause the shank and the drill bit are the same diameter – so it’s easy to drill with! Perfect for large gauge bangles that need big hole pearls! 4mm is great for cutting through thick beach glass and ceramics. Handy to have and may last you a while cause it’s super coated and big! We carry this at the request of our ceramicist friend, Erin!
