The 2-ply staggered design gives you consistent results, even in hard-to-reach locations, unique profiles, and interior contours. Our Scotch-Brite™ Cross Buffs are commonly used in aerospace, automotive and other industrial markets. The purple cleaning and polishing tool uses an aluminum oxide abrasive capable of producing a high luster finish. Aluminum oxide 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. Scotch-Brite™ is a unique surface conditioning product with abrasives incorporated into non-woven fibers. Combining abrasives into the fibers creates an abrasive system that gives you 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.
