Metalsmith: Twist to De-Bur

Metalsmith: Twist to De-Bur
(another installment in a typically occasional series by Christine Cox)removebur-done

After drilling in metal there is often a large bur around the hole. It’s unsightly, dangerous and can throw off how your piece goes together. Eliminate it easily by using a drill bit that’s larger (by far) than the hole you’ve drilled. Chuck the large bit up into a pin vise. Place the metal, bur side up, onto a surface that allows the tip of the drill bit to drop down through the hole. I usually just place the hole over the V in my bench pin, or slide it off the edge of the bench, whichever is easiest. Press down firmly and twist to remove the bur. Caution, don’t go all the way through or you’ll be left with a hole much larger than you intended. Lightly twist back and forth a couple of additional times to clear the swarf and you’re done.

This is also a quick and dirty way to create a countersunk hole. Just push down a little harder as you twist to get the characteristic flared out edge around the hole.
