Offering Ultimate Durability and Edge RetentionWe chose a resin system and convolute construction that allows Scotch-Brite™ EXL-XP Deburring Wheel to run true and consistently while keeping fresh mineral exposed to do the work. Wheel hardness, edge retention, and consistent cut combine to help resist chunking," so the wheel continues to run true. Smooth running and fast cutting reduce operator fatigue while wheel hardness and exposed mineral deliver long life and consistent finishing.Our Scotch-Brite™ EXL-XP Deburring Wheel is filled with fine (FIN) silicon carbide mineral. Silicon carbide is a synthetic mineral that is very sharp and commonly used for low-pressure applications such as paint prep. While it breaks down faster than aluminum oxide, it produces a superior finish.The Science of Smooth The Scotch-Brite™ line of surface conditioning products includes a variety of non-woven synthetic fiber webs and molded wheels impregnated with abrasive minerals. These products are well-suited for cleaning, blending, deburring, finishing and polishing, and improve surfaces without significantly changing the shape or dimension of the workpiece. Scotch-Brite™ abrasives run cool, and resist loading due to their open web construction. This reduces the risk of part discoloration and warping, while extending the life of the wheel. They're designed to help you achieve the surface finishes and part tolerances you desire - making your applications fast, easy and efficient.
