Scotch-Brite Combi-S wheel is a unique finishing wheel composed of alternating Scotch-Brite non-woven flaps and aluminum oxide coated abrasive sheet. Conformable pads provide a large footprint and cushion the abrasive sheets to create a brushed, decorative finish. Designed for surface finishing and blending operations - this wheel is mounted on a 1/4 in spindle that supports the wheel for stability and reduces side loading, helping it remain perpendicular to the work surface. Our Scotch-Brite Combi-S wheel is designed for a variety of surface finishing and blending operations on a wide variety of surfaces such as aluminum, stainless steel, copper and brass. It uses aluminum oxide abrasive mineral. 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 industrial abrasives are unique surface conditioning products with abrasives incorporated into non-woven nylon or synthetic fibers. Combining abrasives with the fibers creates an abrasive system that delivers consistent results for the life of the product. The open web material runs cool and is load-resistant, which keeps the abrasive minerals cutting at high performance by limiting clogging of the fibers.
