Among our XDR brushes, the Scotch-Brite™ XDR Clean and Finish Bonded Cleaning Brush offers the greatest flexibility. It's a good option for operators looking for optimum flexibility and an aggressive cut.We create Scotch-Brite™ cleaning brushes by attaching abrasive discs to a cylindrical core and binding them together with resin. The individually bonded discs make our Scotch-Brite™ XDR brushes more durable, providing 2 to 3 times longer life than standard Scotch-Brite™ Cleaning Brushes. We construct our flap and cleaning brushes differently, so they may be used for different applications. Typical applications for our cleaning brushes include coil cleaning prior to coating, deburring, scale and oxide removal and reclaiming sheet and coil. Scotch-Brite™ XDR brushes have steel cores, so the brush stays sturdy when run on finishing equipment. The steel core adds a level of durability to the brush.Our Scotch-Brite™ XDR Clean and Finish Bonded Cleaning Brush is made with aluminum oxide or silicon carbide mineral, which is interspersed on synthetic fibers bonded with resin. The buoyant, open web construction of the fibers makes the abrasive more responsive. Our Scotch-Brite™ XDR brushes are a good match for cleaning flat surfaces, because they will smooth surface irregularities without sacrificing the geometry of the part. Additionally, the open web resists loading by limiting clogging of the fibers. This keeps the mineral cutting sharper longer.We recommend using a lubricant or coolant when cleaning. It assists in washing away swarf and reduces loading, which helps extend the brush’s service life.Note: When ordering a bonded construction cleaning brush, please allow an additional 1-1/4" to provide clearance for the 5/8" lock collars located at both ends of the brush. For instance, if you require 40" of usable brush width, order a 40" wide brush. This brush, however, when measured at the core will actually be 41-1/4" including the lock collars.
