Scotch-Brite™ EXL Unitized Wheels feature a soft, conformable consistency that effectively smoothes, deburrs and finishes the edges of metal alloys, as well as many plastics and composites. There are a variety of densities and grades starting from a very soft 2 density for applications requiring a conformability to a hard, aggressive 8 density for maximum cut and durability. Our unitized wheel gives a clean edge without smearing, reducing the need for additional clean up and preparation. Designed for optimal performance on a die grinder, the EXL Unitized Wheel minimizes heat buildup during operation, making it ideal for use on heat sensitive materials. Our Scotch-Brite™ EXL Unitized Wheel is filled with abrasive minerals to quickly smooth edges of metal, plastic and composites. It is available with aluminum oxide in fine, medium, coarse and extra coarse grades, and silicon carbide in very fine and fine grades. Scotch-Brite™ is a unique surface conditioning product with abrasives incorporated into non-woven nylon fibers. Combining abrasives with the fibers creates an abrasive system that delivers consistent results over the life of the product. We chose an open-web material that is load resistant and keeps the abrasive minerals cutting at high performance by limiting clogging of the nylon fibers.
