The Scotch-Brite™ Match and Finish High Strength Flap Brush is a durable and aggressive brush ideal for blending and finishing on a variety of metals. This brush combines aluminum oxide mineral with non-woven nylon fibres bonded 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.
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. 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.
