This 43-piece Sunburst® Assortment contains six each of 7/8" Dual Radial Discs in all grits plus one mandrel. Dual Radial Discs are impregnated with a specially treated ceramic abrasive grain, resulting in longer life and faster results requiring no polishing compound. Safer and more flexible than wire brushes, Dual Radial Discs are conveniently double-stacked, making them more economical and faster to use. This product is long-lasting and cool-running, with operating speeds of 3,000 - 18,000 RPM. Lower speeds allow a softer touch, greater flexibility, and more subtle results. Higher speeds provide more aggressive material removal.
