Scotch-Brite™ match and finish high strength flap brush is durable and aggressive, great for blending and finishing on a variety of metals. Scotch-Brite™ match and finish high strength flap brushes combine aluminum oxide mineral and our non-woven nylon fibers with resin. Sharp-cutting aluminum oxide mineral leaves a fine finish, while the spongy, open web responds to surface irregularities and maintains part geometry. This brush is one of the most durable among all the Scotch-Brite™ flap brushes, so it's good for graining stainless steel, blending handling marks and imperfections, cleaning around welds and light deburring. Easy attachment Scotch-Brite™ match and finish high strength flap brush may be used on the 3M™ 1HP match and finish sander (sold separately) and is available in 5/8-11 threaded inserts for easy thread on/off attachment as well as a 4-way keyway attachment system. Under normal use (abiding by recommended rpm), the Scotch-Brite™ match and finish high strength flap brush minimizes chatter risk. As the brush spins, flaps rotate centrifugally and make continuous contact with the workpiece. By lapping the surface, the flaps reduce the residual traces or marks that tend to be left by singular discs or discs ganged on a shaft. Welding, bending, stamping and other fabrication processes can seriously mar the mill finish of stainless steel and other metals - requiring a lot of time and many tricky, painstaking steps to restore the finish to its original condition. Scotch-Brite™ flap brushes are often the last step in a Series -ushered in to a sequence when the surface is ready for a final finish. For weld blending and finish restoration, flap brushes may be preceded by other abrasives like a fiber disc for weld removal and a belt that sets the grain. With a little practice, users can feather in and out of the repair area with their flap brush, reducing chatter and marks. Some flap brushes are more durable, whereas others are more aggressive. Non-woven 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 t
