Product Description Scotch-Brite Roloc Bristle Disc, using proprietary ceramic abrasive grain blended with aluminum oxide and molded, flexible bristles, provide more surface contact than wire brushes and retain abrasive properties throughout the life of the disc From the Manufacturer The 3M™ Scotch-Brite™ Roloc™ Bristle Disc, using 3M™ Ceramic Abrasive Grain and molded, flexible bristles, provide more surface contact than wire brushes and retain abrasive properties throughout the life of the disc. The fast-running disc combines superior cutting action with the Roloc quick change attachment system to efficiently clean, strip, deburr, blend, finish, polish, scratch, and remove rust and coatings without damaging the base material. Under normal use, bristles remain safely in place and can achieve the desired finish using light pressure. The Scotch-Brite™ Roloc™ Bristle Disc works well on steel, aluminum and a variety of other metals, in general maintenance, as well as automotive and engine rebuilding applications.3M™ ceramic abrasive grain is a ceramic mineral designed using a 3M patented process to enhance toughness and hardness of the grain. For increased performance, Roloc™ Bristle Discs feature aluminum oxide blended with 3M™ ceramic abrasive grain for one of the hardest, longest-lasting minerals available. Perfect for moderate to heavy stock removal, ceramic abrasives are engineered to cut fast and handle intense heat and stress applications. Ceramic aluminum oxide blend surpasses aluminum oxide abrasives in cut-rate, durability, and makes an excellent choice for difficult grinding applications.Scotch-Brite™ industrial abrasives are unique surface conditioning products with abrasives incorporated into non-woven nylon or synthetic fibers. Combining abrasives with the fibers creates an abrasive system that delivers consistent results for the life of the product. The open-web material runs cool and is load resistant, which keeps the abrasive minerals cutting at high performance by limiting clogging of the fibers.For more than a century, 3M has applied innovation and technology to improving our customers’ lives and supporting their business goals.
