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).
If you need to enlarge the holes in the beads or smooth them out, you are in the right place. In the category, you will find hand drills for fine adjustment of bead holes, including a vice for attaching them. You will also find sets of micro-drills for drills here, if the older ones become dull or abraded.
