The Scotch-Brite™ Cut and Polish Disc is engineered to produce satin or high-lustre finishes and may be used for cleaning or light deburring on a variety of metals. This disc's durable open-web construction is designed to resist loading and greatly increase the life of the disc.The Scotch-Brite Cut and Polish Disc features an aluminum oxide mineral abrasive, which is a popular mineral choice among industrial 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, aluminum oxide is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including working with ferrous alloys.
