3M Scotch-Brite SE-DR Coarse Grit, 3" x NH Aluminum Oxide SE Surface Conditioning TR Roloc Disc Brown (25 Pack)

FROM THE MANUFACTURER The 3M™ Scotch-Brite™ Roloc™ SE Surface Conditioning Disc combines a coarse, non-woven disc to perform heavy-duty deburring and finishing with the efficiency of the Roloc quick-change attachment system. The heavy-duty non-woven fiber construction conforms well to help preserve irregular or contoured surfaces and the Roloc backing supports the disc to allow 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 SE Roloc disc ideal for heavy duty deburring and finishing.SE surface conditioning discs use 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.
