Restoring Finishes
Scotch-Brite™ Match and Finish High Strength Flap Brush combines 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. Scotch-Brite™ Match and Finish High Strength Flap 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 & 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.

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.

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, the Scotch-Brite™ Match and Finish High Strength Flap Brush may be preceded by other abrasives like a fibre 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.
