Small Diamond Twist Drills
Eternal Tools
SKU:DTD1075
Available in sizes from 0.75mm to 3.00mm. Straight shank.
These are like regular twist drills but coated in diamond grit, making them suitable for use on hard materials such as stone, glass, ceramics, porcelain, and shells. They are designed for enlarging holes rather than drilling holes, making them perfect for enlarging holes in pearls.
They have diamond grit running along the tip and sides, allowing them to remove material horizontally and vertically. They are especially good for widening existing holes. Try them on your beads.
They are used by lamp workers and bead jewellers and by many industrial ceramic companies. If you need to demist your double glazing, use a 3mm twist drill in the corner at the bottom. Magic!
