The Scotch-Brite™ AL Surface Conditioning Disc TN Quick Change cleans, finishes, blends and deburrs a variety of substrates, including ferrous and non-ferrous metals. It strikes the perfect balance between strength and softness. Use this disc to refine coated abrasive scratches, blend machine marks or mill lines, remove handling defects, or prepare a part to be painted. Effectively Remove Burrs and Contaminants without Damaging Base MaterialScotch-Brite™ products can help make your tough jobs easier. The Scotch-Brite™ AL Surface Conditioning Disc, specifically, helps achieve paintable finishes in fewer steps while maintaining the part geometry. It's designed to lightly grind, finish and blend — using its unique blend of open web and mineral to minimize imperfections and deliver a fine finish. Aluminum Oxide Mineral Cuts Fast and SharpAluminum oxide mineral is interspersed in the disc’s open web. Aluminum oxide is a popular choice among industrial professionals given its durability and sharp cut. Moreover, aluminum oxide is known for being friable, meaning it fragments under heat and pressure in order to self renew. Friability keeps the mineral cutting sharp. While all discs use aluminum oxide, we offer Scotch-Brite™ AL Surface Conditioning Disc TN Quick Change in three grades: very fine (VFN), medium (MED) and coarse (CRS). In this way, operators can choose a grade that’s tailored to their substrate and desired finish. Quick Change System for Easy Power Tool AttachmentWe included a Quick Change attachment on this disc so operators could easily swap between discs. It also makes for quick power tool attachment, helping enhance productivity and throughput. To attach the disc, operators simply need to attach it to a hub and faceplate (sold separately) by threading the disc onto the tool shaft threads. These special attachment types were designed to expedite the time it takes to swap out discs in a sequence, helping you reduce process time and improve throughput. The Scotch-Brite™ AdvantageScotch-Brite™ products incorporate mineral into non-woven nylon fibers. Breakthrough fiber coating technology allows Scotch-Brite™ abrasive products to cut faster and produce a more consistent scratch. The open-web material is load resistant and keeps the abrasive minerals cutting at high performance by limiting clogging of the nylon fibers. As the nylon fibers break down gradually during grinding, they expose fresh mineral, so you get that consistent sharp cut – part after part.
