Similar to our small solid diamond drill bits, these drill bits are hollow allowing water to circulate more freely. They are ideal for drilling holes in glass, tile, ceramic and porcelain, glazed pottery, beads, pebbles, stone, slate, petrified wood, fossilized bone and rock. For those tough pieces of sea glass, they work a dream!

“I use Eternal Tools diamond core drills on glass about 1mm-3mm thick and can normally drill between 200 and 300 hundred holes.The best ever result was 450 holes with one drill bit ( impressive) I use slow speeds, always gently pumping up and down and drill constantly under water”
