If you need help with finishing, call SAS for experienced advice. Tough but flexible, these discs conform to the contours of the work piece where intricate designs, tubes or corners make finishing, cleaning and deburring difficult. They're also safe for the user as they eliminate the dangers of flying metal wires posed by wire brushes and also can replace chemical use in some applications. In addition, their unique, patented design resists gumming and loading, so bristle discs work fast on soft or hard metals to produce a consistent, uniform finish. One-inch 3M radial bristle discs are suitable replacements for hand files, wire brushes, hand scrapers and traditional grinding discs used for sanding, surface preparation and coatings removal.
All grades are color-coded for easy identification.
You may find that Scotch-Brite wheels can accomplish the same tasks when using abrasives of these larger diameters. These discs are worth a try. Most jewelry supply companies now carry a wide array of sizes and grits. Though their lifespan is shorter than traditional bristle wheels, they certainly have many applications including surface preparation for soldering and brazing without the need to remove buffing compounds. They are also excellent for removing corrosion.
