Scotch-Brite™ cut and polish wheels are built for aggressive blending and finishing applications. Harder than other finishing wheels, cut and polish wheels are good for defect removal or heavy scratch blending and produces a finish with a tight scratch pattern. Scotch-Brite™ cut and polish wheels use aluminum oxide abrasive, which is a popular 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. Due to its fast cut rate, hardness and strength, it 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 ferrous alloys. Scotch-Brite™ industrial abrasives are unique surface conditioning products 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. Cut and polish wheels help to remove surface defects and coarse grind lines, blend forging marks and machining mismatches while leaving a uniform grain finish. These wheels are available in a range of diameters and widths and can be used with robotics, inline sanders, bench motors, back stands and centerless grinders.
