Question:

I read your information on choosing the size of a cup burr, but have never heard of that tool. What is a cup burr used for?

-Dorothy in Prineville, Oregon

Answer:

Hi Dorothy, a “cup burr,” or cup bur, is used to round off the end of either a square or round wire, removing the “burrs”. We covered the different sizes in this post: Cup Bur Sizes for Wire Gauges.

Most wire artists use this little tool when making their own ear wires. Wire-Sculpture Faculty member Sonja Kiser demonstrates the procedure nicely in our Free video tip, Removing Wire Burrs. Thanks for asking!
