Our Scotch-Brite™ Cut and Polish Disc D5 uses a durable, non-woven, open-web construction is load resistant, runs cool, and provides conformability while the aluminum oxide abrasives work to deliver consistent cutting action. The 1/4" shank is suitable for power tools with a 1/4" drive, die grinders, and inline sanders. We chose aluminum oxide abrasive, which is a popular choice among industrial professionals because of its cut-rate and long life. This mineral is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives, such as garnet, quickly wear down with use. Due to its high cut-rate, hardness, strength, and low heat retention, aluminum oxide mineral is widely used in grinding applications in addition to sanding and finishing use. Aluminum oxide is suitable on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys. Our Scotch-Brite™ industrial abrasives are a unique surface conditioning product with abrasives incorporated into non-woven nylon or other synthetic fibers. Combining abrasives into the fibers creates an abrasive system that delivers consistent results for the life of the product. The open-web material is load resistant and keeps the abrasive minerals cutting at high performance by limiting clogging of the fibers.
