Product Description Scotch-Brite Roloc Surface Conditioning Discs SC combine the cutting efficiency of a nonwoven disc with the changeover speed of the 3M Roloc Quick-Change Attachment System. These discs use an open web fiber that runs cool, reducing the risk of substrate discoloration and warping, while remaining load resistant to keep the abrasive minerals cutting at high performance. This helps limit clogging, extending the disc's work life in a range of tasks. These features make Scotch-Brite Roloc Surface Conditioning Discs SC a versatile, reliable solution for a variety of applications. From the Manufacturer The 3M™ Scotch-Brite™ Roloc™ Surface Conditioning Disc combines a durable, non-woven disc with the efficiency of the Roloc™ quick-change attachment system for an effective disc that cleans, finishes, blends, and deburrs. The non-woven fiber construction conforms well to help preserve irregular or contoured surfaces and the Roloc™ backing supports the disc for aggressive cutting. The open-web fiber runs cool and resists loading while the aluminum oxide abrasives provide a high cut-rate for consistent finishing. The Roloc™ attachment system offers quick and easy disc change-out, making the Roloc™ Surface Conditioning Disc ideal for a range of tasks including blending, deburring, and finishing.the Scotch-Brite™ Roloc™ Surface Conditioning Disc uses aluminum oxide abrasive. Aluminum oxide is a popular choice among industrial professionals because of its cut-rate and long life. This mineral is 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 its high cut-rate, hardness, strength, and low heat retention, aluminum oxide mineral is widely used in grinding applications in addition to sanding and finishing use. Aluminum oxide is suitable on a wide variety of substrates in both woodworking and metalworking, including ferrous alloys.3M™ Roloc™ TR quick change discs are smaller discs that have a plastic threaded button or screw designed to easily and quickly screw onto a Roloc™ TR disc pad (sold separately) so that operators can conveniently change discs with a simple twist-off, twist-on motion. The Roloc TR system provides a secure attachment even for heavy-duty applications, and the variety of available 3M Roloc discs allows swapping from one application to the next in seconds. Each TR attachment button is also color-coded to identify its grade, making it easy to grab the grade required for different applications.For more than a century, 3M has applied innovation and technology to improving our customers’ lives and supporting their business goals.
