Before forming wire, take a moment to round the end using a cup bur. This is especially important on the end of an ear wire to clean up the ragged cut end. Use in a swivel pin vice or in a rotary hand tool. Also, use on balled wire rivets to clean up the head. Use Cut Lube on the bur to keep it cool. To use by hand, insert the bur in a pin vice, place the cup over the wire end and twist in a clockwise direction several turns. Inspect the end of the wire using magnification. If the wire is not cleanly rounded, give a few more twists.

"I use 21 ga wire to bend the ear wires for earrings I make. I have always ised a file to round the tip. Tying 20 or so pair at once is time consuming and filing takes a bit of time. The cup bur, along with my new Foredom saves a lot of time, and gives me a perfect result with the tap of my foot."
— Loren G. (5/5)

"Wow! I was so tickled to finally find a source for cup burs. I have looked for a couple of years at the local gem faires but nothing has been available. Been using this old one a long time and the difference is amazing, using a new bur to round off earring wire ends."
