    I have one of these cup burrs, too. What size wires does the 1.8 mm tool work on?

      Hi Linda, great question! This cup burr will work on wire up to 14-gauge. If you check out the “AWG to Inches and MM Chart” at the bottom of this page, you’ll see that 1.8mm is right between 14- and 12-gauge. You want the cup burr to be a hair larger than the wire you’re working on. Hope this helps!

        Thanks, Rose. I think the one I bought at my LBS several years ago is defective. I’ll have to get a new one when I put in my next order here.

    Thank you! I have a cup burr but thought you could only turn it one way! You learn something new everyday, thank you!
