Works Well on a Variety of Substrates Under normal use, the flexible bristles on the Scotch-Brite™ Roloc™ Radial Bristle Disc remain safely in place and can achieve the desired finish using light pressure. We designed our disc to last longer than wire and other abrasive discs and it works well on aluminum, brass, bronze, carbon steel, cast iron, stainless steel, and other metals. It was engineered for general industrial, aerospace, automotive, metalworking, transportation, and automotive applications. Ceramic Aluminum Oxide Provides Fast Cutting Action 3M™ ceramic aluminum oxide blend is a ceramic mineral designed using a proprietary process to enhance toughness and hardness of the grain for a higher level performance.Ceramic aluminum oxide blend is engineered to fracture frequently and surpasses aluminum oxide abrasives in both cut-rate and durability.Perfect for moderate to heavy stock removal as well as finishing, ceramic abrasives are built to cut fast and handle intense heat and stress applications. Roloc™ Attachment for Easy Swap Out of Discs The Scotch-Brite™ Roloc™ Radial Bristle Disc is designed to be used with portable hand tools, so operators may facilitate direct contact between the abrasive and the surface area at the exact location where it's required. The Roloc™ attachment makes changeouts between discs even easier. The disc locks securely with 1/2 turn on and 1/2 turn off and the Roloc™ disc pad assembly is designed to fit a variety of tools with or without collets or chucks and is ideal for use on right angle or straight shaft air tools. The Many Benefits of Open Web Abrasives Scotch-Brite™ abrasives are unique surface conditioning products with abrasives incorporated into non-woven fiber matrix. Combining abrasives and non-woven material 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.
