3M 7010309990 Scotch-brite Mb-dc Metal Blending Disc 5 Inch

Product Description

The 3M 7010309990 Scotch-Brite MB-DC Metal Blending Disc is a 5-inch non-woven abrasive disc designed for blending, finishing, and cleaning on metal surfaces. Built with silicon carbide mineral at medium coarseness, it cuts through weld burns and surface scratches efficiently. The nylon web construction resists melting on hot welds, so technicians can begin blending immediately after welding without a cooldown wait. Sheet metal fabricators, welders, and metal finishing trades use this disc for surface prep and satin finishing work.

This disc is suited for blending surface scratches, removing weld discoloration, and producing consistent satin finishes on stainless steel and other metals. It also performs general cleaning tasks on wood and synthetic surfaces. The open web structure resists loading, extending disc life during repeated passes. The disc mounts on a quarter-inch tool arbor, making it compatible with standard right-angle grinders and die grinders used in fabrication and field service environments.
