Scotch-Brite cross buff polishes, cleans, satin finishes, denibs and defuzzes the interior diameters of metal components, such as lifter bores, valve bodies, valve spools and tubing. Conformability of the nylon web makes this abrasive useful for removing surface oxidation, rust and corrosion on dies and molds prior to coating and polishing. 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 metal working 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.
