Scotch-Brite™ Match and Finish Combi Flap Brush combines the cutting action of 3M coated abrasives with the finishing action of Scotch-Brite™ material for metal finishing and blending – all in one step.

Restoring Finishes
We engineered the Scotch-Brite™ Match and Finish Combi Flap Brush by combining aluminum oxide mineral and nonwoven 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 helps restore final finishes on fabricated metals like stainless, aluminum and brass. Among all Scotch-Brite™ flap brushes (PDF, 500 Kb), Scotch-Brite™ Match and Finish Combi Flap Brush tends to be the most aggressive, because it fuses the cutting action of a coated abrasive with the finishing action of non-woven material.

Easy Attachment
Scotch-Brite™ Match and Finish Combi Flap Brush may be used on the 3M 1HP Match & Finish Sander (sold separately) and is available in 4-way keyway attachments for easy thread on/off attachment. This system speeds swapping out of discs, especially when different sizes or grades are required for a sequence.

Under normal use (abiding by recommended RPM), the Scotch-Brite™ Match and Finish Combi 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 eliminate the residual traces or marks that tend to be left by singular discs or discs ganged on a shaft.

Scotch-Brite™ Flap Brushes: The Final Step
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 fibre disc to remove 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. Although not required for most applications, grinding lubricants, coolants or compounds may be used with these brushes if necessary.

The Many Benefits of Open Web Abrasives
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 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.
