Set of Steel Hand Twist Drill Bits - length 29-61 mm - diameter 0.8-3 mm
Set of ten steel micro drills for beads with a length of 29 - 61 mm and a diameter of 0.8 - 3 mm. The drills are designed for hand drills from our shop, but they can also be used in classic electric or cordless drills. If you are interested in enlarging the holes of the beads, we recommend using hand drills rather than electric ones, as the speed of electric beads usually cannot be reduced and without water cooling, the beads can very easily overheat locally and crack.
The drills do not have diamond tips, so we do not recommend them for drilling holes in mineral beads.
THE PRICE IS FOR 1 SET (the set contains 10 drills).

When enlarging holes, do not perform step enlarging - eg from 0.5 mm to 2 mm. On the one hand, there is a risk that the hole will be crooked and on the other hand, the bead will break. Enlarging needs to be done gradually over several sizes of drills to avoid defects or destruction of beads.
The drills do not have diamond tips, so we do not recommend them for drilling holes in mineral beads.
