This set includes a wood top pin vise and two cup burs. One bur has an inside diameter of 1.2mm and the other is 1.8mm. These cup burs are used for rounding the ends of various sizes of wire. The pin vise can also be used for other tasks, more easily, because of the round comfortable head.
I use this tool to round the ends of handmade earwires.....very quick, very useful :) There is one collet under the handle and one under the tip.

So glad to have found this little cup bur, it makes finishing wire-ends a doddle!
This works perfectly. I used it on the ends of the ear wires I made and they are so smooth now. I don't know I'd do without this tool.
Works beautifully! Don't know how I made ear wires without them.
So glad I got this! Wish I'd had it last year when making earrings for a friend's wedding.
