Drilling Semiprecious Beads with Diamond bits
Posted by Orlando on

If you would like to drill semiprecious beads or enlarge holes for stringing or knotting I suggest using diamond tipped drill bits. I like the tapered type for smaller holed beads and the cylinder type for larger holed beads. Always drill slowely so you don’t burn the diamond coating off. You can dip the diamond bit into water to cool.
