Scotch-Brite™ Match and Finish High Strength Flap Brush, 4-1/2 in x 4 in x 5/8 in-11 7A MED, 1 ea/Case

Scotch-Brite™ Match and Finish High Strength Flap Brushes combine aluminum oxide mineral and non-woven nylon fibers with resin. The 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, making it ideal for graining stainless steel, blending handling marks and imperfections, cleaning around welds, and light deburring.

The Scotch-Brite™ Match and Finish High Strength Flap Brush can be used on the 3M 1HP Match & 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.

When used under normal conditions (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, used 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. Depending on the desired finish, users might opt for a more or less aggressive grade.

Nonwoven technology makes 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 not only enhance productivity but also increase operator safety by reducing the need for cleaning chemicals and pastes and replacing wire brushes that can break off and cause injury. From aesthetic finishing to weld blending, deburring, and more, Scotch-Brite abrasives work fast and deliver consistent results, part after part.
