These quality twist drills are electroplated with diamond particles, they are the ultimate for drilling glass, gemstones, sea glass, pearls or ceramics (for drilling metals use a regular steel drill bit).
The technique for drilling is slightly different from the drilling metals; they need to be used at a slow speed and water must be used as a lubricant. They are available in a variety of useful diameters.
If you are not familiar with the technique, we recommend purchasing our 'Using Diamond Coated Drill Bits' advice leaflet.
Available in a range of sizes:
If you are considering purchasing these for enlarging the holes in beads you may prefer our deluxe bead reamer set which is specifically designed for this purpose.
