Efficient Gasket Removal with Minimal Heat Buildup Engineered with non-woven nylon fiber, our Scotch-Brite™ Roloc™ Gasket Removal Disc removes gaskets without requiring re-work, and provides consistent results piece after piece. The open-web construction of our Scotch-Brite products minimizes heat buildup during operation, making this disc ideal for use on steel and aluminum metals. The disc is filled with tough aluminum oxide mineral that cuts fast to remove old gasketing quickly, and the small-sized disc enables access to tight corners. The Roloc attachment allows use of both the edge and surface of the wheel without interruption of mounting hardware. It requires a 3M™ Roloc™ Disc Pad Assembly (sold separately). Secure and Convenient Quick Change Attachment Our 3M™ Roloc™ TR quick change wheels and discs have smaller diameters and feature a plastic threaded button or screw designed to easily and quickly screw onto a Roloc™ Disc Pad Assembly (sold separately) so that operators can conveniently change wheels or 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 products allows swapping from one application to the next in seconds. The Scotch-Brite™ Advantage Nonwoven 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, limiting clogging of the abrasive. 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.
