Scotch-Brite™ Match and Finish Flap Brush, CF-MF, 5A Extra Coarse, 4-1/2 in x 8 in x 1.25 in, Keyway Core, 1 ea/Case

The Scotch-Brite™ Match and Finish Flap Brush is a radial brush that has rows of open web, providing consistency and conformability for finishing on various metals. It is available in different grades and minerals, allowing operators to choose the combination that best suits their application.

The Scotch-Brite™ Match and Finish 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 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.

These abrasive 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 leveling the weld 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. Scotch Brite material combines fiber strands, resin, and abrasive mineral to form 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.
