3M conditioning abrasive discs combine aggressive cutting features with superior-conforming, non-woven fiber construction great for auto body applications such as deburring, finishing and polishing. 2 in (50 mm) conditioning discs feature durable, fast cutting aluminum oxide mineral abrasive, suitable for all metals, and Roloc backing for support and quick-change outs. For auto body applications including gasket removal, disc brake finishing and metal polishing, our 3M conditioning abrasive discs provide the ideal balance of aggressive cutting and consistent finish. Fine grade medium grit is made from durable aluminum oxide that self-fractures during use, continually exposing fresh cutting surfaces to keep the disc sharper longer. Durable non-woven fibers act like tiny springs, providing superior conformity and helping preserve irregular or contoured surfaces. This combination also resists loading and reduces heat for longer disc life. The Roloc backing supports the disc for aggressive cutting, and works as part of our Roloc attachment system that allows for quick snap on change outs. Aluminum oxide mineral is a popular choice among industrial and auto body professionals because of its fast cut-rate and long life. This mineral makes 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 their fast cut rate, hardness, strength, and low heat retention, they are widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in metalworking, including ferrous alloys. 3M Roloc quick-change discs have a plastic threaded button or screw designed to easily and quickly attach to a Roloc disc pad so that operators can conveniently change discs with a simple twist off, twist on motion. The Roloc system provides a secure attachment, and the variety of available 3M Roloc discs allows swapping from one application to the next in seconds for efficiency during multiple step finishing processes. It's no accident that our 3M conditioning abrasive discs provide a sharp cut abrasive and still deliver a consistent finish. We've employed technologies including our unique open web design, which uses non-woven fibers to keep abrasive particles flush even with irregular surfaces. So auto body professionals can get the most from their sanding skills during jobs that require artful abrasive tact and from their auto body businesses.
