Aluminum Oxide MineralAluminum oxide mineral is incorporated in Scotch-Brite™ Roloc™ General Purpose Scuffing Wheel. We chose this mineral, because it is a popular choice among industrial professionals who favor the fast cut rate and long life. Aluminum oxide's hardness, strength and low heat retention help the wheel withstand repeated wear.3M™ Roloc™ Attachment SystemScotch-Brite™ Roloc™ General Purpose Scuffing Wheel features a 3M™ Roloc™ attachment system, which allows for swift and easy wheel to tool attachment. The wheel simply locks in place with a quick 1/4 turn and is fastened to the holder pad (sold separately), which, subsequently, attaches to the tool. We included the 3M™ Roloc™ attachment system to help expedite projects and enhance productivity.The Many Benefits of Open Web AbrasivesNonwoven technology makes our Scotch-Brite™ industrial abrasives unique. A combination of fiber strands, resin, and abrasive mineral forms a thick, open web. The spring-like nature of the fibers responds to contours and effectively removes unwanted burrs, soils, and contaminants while maintaining the geometry of the workpiece, which in turn reduces rework and boosts productivity. Gaps in the web allow swarf to escape, so debris does not clog the mineral. Fibers in the web continually break down with use to reveal fresh mineral for exceptional consistency, superior cut performance, and extremely long service life. Scotch-Brite products may enhance productivity while reducing the need for cleaning chemicals and wire brushes. From aesthetic finishing to weld blending, deburring, and more, Scotch-Brite abrasives work fast and deliver consistent results, part after part.
