The 3M™ Roloc™ Disc 361F offers a quick-change attachment and provides durability and high performance for grinding, blending, deburring, and finishing on all metals. Fast-cutting aluminum oxide abrasive grains are bonded to the heavyweight cloth backing with durable, heat-resistant resin that supports both wet and dry applications.Aluminum oxide abrasives are a popular choice among industry professionals because of its fast cut rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut rate, hardness, and strength, it is widely used in grinding, sanding, and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys. Heat-resistant resin is a sturdy binding agent that adheres the abrasive to the backing and maintains the stability of the bond even in conditions of high heat or pressure. Cloth-backed discs are known for their durability and flexibility. They're a good first choice when working with metal or for heavy wood stock removal. The 3M Roloc Disc 361F is available for use with the following 3M Roloc attachment systems: TSM, TR, TP and TS. Please select discs with the attachment design made for your system.
