Scotch-Brite™ clean and strip disc was designed to help operators tackle tough metalworking challenges, think paint prep and coating and corrosion removal. When removing unwanted contaminants and stubborn imperfections - or smoothing a rough surface - it's a good idea to have a load-resistant, sharp cutting abrasive on hand. Scotch-Brite™ clean and strip disc has all the benefits operators have come to expect from Scotch-Brite™ abrasives, including good load-resistant and consistent cutting action. In fact, its ability to withstand debris makes it a good match for high production environments and projects that generate a lot of dust, such as coating and corrosion removal. Scotch-Brite™ clean and strip disc features a standard attachment system and may be connected to a backstand, right angle grinder or die grinder. Nylon fibers on Scotch-Brite™ clean and strip disc are interspersed with extra coarse (XCS) silicon carbide mineral. We chose extra coarse (XCS) mineral, because it cuts more aggressively than minerals in a finer grade. Among synthetic minerals, silicon carbide is one-of the sharpest. It breaks down faster than aluminum oxide but leaves a finer finish. As a Scotch-Brite™ product, this disc is engineered with open nylon web, which is why it's such a great match for cleaning welds, removing rust and stripping paint. The gaps between nylon fibers permit debris to escape. The benefits of this are twofold. First, it enhances the abrasive's ability to withstand loading. Second, because the abrasive does not get clogged with debris as easily, it has prolonged service life. The nylon fibers break down continuously during grinding, revealing fresh mineral for ongoing sharp cutting action and consistent finishes part after part. 3M™, 7000028474, Clean and Strip Disc, 6 in Diameter Disc, Very Coarse Grade, Silicon Carbide Abrasive, 4000 RPM Maximum
