In manufacturing the Scotch-Brite? Roloc? Surface Conditioning Disc, we combined our durable, non-woven disc with the efficient 3M? Roloc? quick-change attachment system for an effective disc that cleans, finishes, blends, and deburrs. Our non-woven fiber construction conforms well to help preserve irregular or contoured surfaces and the Roloc? backing supports the disc for aggressive cutting.
