Why use the cup bur jewelry tool to round the cut end of jewelry wire?
When you cut jewelry wire with a flush cutter tool, the cut end of the wire will have some residue of the cut called burs that are rough. For most jewelry making projects, you can hide these burs and the rough nature of the cut wire by ending the wire in a loop or circle of wire. That way people won't see or feel the cut end of the wire. This technique works for most jewelry projects, but does not work when making ear wires. With ear wires, the cut end of the jewelry wire must be rounded because any roughness would detract from the item once it was worn.
What size jewelry wire will work with the cup bur jewelry tool?
Given that the most important use for the cup bur tool is for making ear wire findings, the cup bur tool was designed to work with 20 and 21 gauge wire. 20 and 21 gauge jewelry wire is the most common size of wire used when making ear wires. While the cup bur tool was designed to work with 20 and 21 gauge, it will also work with 18 and 22 gauge wire. The cup bur tool will not work with 16 gauge wire or larger and similarily is not commonly used with 24 gauge wire or smaller.
