Small Diamond Twist Drills
0.5mm - 3.00mm
These drills are like a regular twist drill but coated in diamond grit making them possible to use on hard materials such as stone, glass, ceramics, porcelain, and shell. They are perfect for enlarging holes in beads.
HINT: Use for opening up holes
These drill bits have diamond grit running along the tip and sides allowing them to remove material horizontally as well as vertically, they are especially good for widening existing holes. Try them on your beads.
These twist drills are used by lamp workers and bead jewellers and also by many industrial companies for ceramics. And if you need to de-mist your double glazing, try using a 3mm twist drill in the corner at the bottom. Magic!

Will your drill bits fit my drill?
Hi Clare, Our drill bits will fit all rotary drills so long as you have an adjustable collet or chuck with which to hold the shank of our very small drill bits. Sometimes when buying a drill they will come with an adjustable collet but if you find you are in need of one then we supply either a Dremel Multi Chuck (DMC4486) or a Dremel Collet Nut Kit (DCNK4485).
