Eliminate Steps, Save Time Scotch-Brite™ Light Grinding and Blending TN Quick Change Discs can often single-handedly prepare surfaces for painting, where a 3 mil or greater paint thickness is being applied, without adding a final dual-action sanding step. Tough and Sharp 3M™ ceramic aluminum oxide abrasive is a ceramic mineral designed using our 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. The TN Quick Change Advantage Discs with a TN attachment are designed to allow operators to conveniently change discs fast and easily to accommodate different tasks or multi-step finishing processes. The TN attachment provides a secure attachment even for heavy-duty applications, and the variety of available discs allows swapping from one application to the next in seconds. Each disc is also color-coded to identify its grade, making it easy to grab the grade required for different applications.
