A friend of mine who owns a jewelry supply house recently made-up
some 1" miniature Scotch-Brite wheels in both maroon (deburring) and
tan (very course). Depending on what you're working on, they work
great and are a fraction of the price of 3M's radial bristle wheels.
Check out their Web site at: http://www.alcanjewelrysupply.com
They're not pictured on the site, but call their toll-free number
and get pricing.
