Replace Just the Contact Wheel, Not the Entire Contact Arm AssemblyKeeping your 3M™ File Belt Sander (PN 33573 and 33575) operating at peak performance becomes faster and easier with our 3M™ File Belt Sander Contact Wheel Replacements. This convenient kit includes a durable rubber contact wheel and the screw needed to quickly install it into the end of the contact arm. Instead of replacing the contact arm assembly - or the entire tool - you can simply remove the old contact wheel and screw the new one into place.Designed specifically for your 3M™ File Belt Sander, the contact wheel keeps the abrasive belt in precise contact with the substrate, and is critical for smooth and effective operation of the sander. The rubber contact wheel is designed to add flexibility and exert less pressure on the abrasive during use, helping to lengthen the life of the abrasive belt.About the 3M™ File Belt SanderFeaturing a lightweight design and a narrow profile, the 3M™ File Belt Sander is ideal for automotive work and is especially suitable for sanding or grinding in tight areas, such as between door panels or along sharp contours. It provides the power and maneuverability you need for a range of jobs including spot weld and hem flange removal; surface prep; urethane, seam sealer and gasket removal and weld clean-up. In many cases, the belt sander can replace a traditional spot weld drill.This file belt tool is designed for use with 3M™ Cubitron™ II Abrasive Belts, created for performance grinding and long abrasive life. It features a replaceable rubber contact wheel that is designed to provide added flexibility and exert less pressure on the abrasive during use, further lengthening the life of the abrasive belt.About Cubitron™ II Abrasives3M™ Cubitron™ II abrasive products have raised the bar for high-performing abrasives. Engineers started with 3M™ Ceramic Abrasive Grain and used technology to electrostatically orient each triangular structure on the backing to form sharp peaks and maximize cutting potential. These peaks act like individual cutting tools that slice through metal, and continuously shelf-sharpen as the points break off, ensuring extended high performance in heavy-duty production applications. The grains wear evenly and provide extra-long life and consistency with less grinding pressure. The result is that Cubitron™ II products out-cut and outlast every conventional ceramic industrial abrasive product on the market, maximizing productivity and minimizing belt stress and operator fatigue.Better Science for Better Sanding from 3MOur 3M™ File Belt Sander Contact Wheel Replacements is part of a complete portfolio of abrasives and tools specifically designed for auto repair.
