This wheel is mounted on a 1/4″ 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 metalworking, 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.
