3M™ 7010290833 3-1/2 x 10 x 1-1/4 80 Grit 6 Ceramic Medium DB-FB Scotch-Brite™ Deburr & Finish PRO Combi Flap Brush

3M™ Scotch-Brite™ 7010290833 3-1/2 x 10 x 1-1/4 80 Grit Deburr & Finish PRO Combi Flap Brush DB-FB 6 Density Ceramic Medium

Flap Brush Features:

• Designed to deburr and finish in one step, reducing the need for multiple processing steps, enhancing throughput and productivity
• Flap brushes make continuous contact with the workpiece, resulting in more consistent finishes
• Flap construction helps minimize risk for chatter or residual marks
• Open web responds to surface irregularities without compromising part geometry
• Fibers in the web continually break down with use to reveal fresh mineral resulting in long service life

Form and Function

Individual flaps on the Scotch-Brite™ Deburr & Finish PRO Combi Flap Brush are made with nylon fibers and two different kinds of mineral: silicon carbide and proprietary 3M Precision Shaped Grain. Nylon fibers are interspersed with mineral, which is adhered to the fibers using resin. As the flaps abrade the workpiece, the fibers break down gradually, revealing sharp mineral for consistent cutting action. Moreover, the open web is buoyant and spongy, so the flaps can respond to surface irregularities without compromising part geometry or dimensions.

The Outstanding Performance of 3M Precision Shaped Grain

3M Precision Shaped Grain is produced using 3M technology to create triangular shaped ceramic mineral grains. The razor-sharp corners of each triangle act like individual cutting tools that slice through metal, and continuously shelf-sharpen as the points break off, ensuring extended high performance in heavy-duty production applications. The grains wear evenly and provide extra-long life and consistency with less grinding pressure.

The Anatomy of a Flap Brush

Aside from its sharp cutting action and responsive web, the brush's flap construction shapes the results. The individual flaps are adhered to a fiberglass core. Under normal use (abiding by recommended RPM), the brush minimizes chatter risk. As it spins, flaps rotate centrifugally and make continuous contact with the workpiece. By lapping the surface, flaps reduce the residual traces or marks that tend to be left by singular discs or discs ganged on a shaft. The brush may be used with a variety of tools, including backstand, match and finish sander and inline sanders.

The Many Benefits of Scotch-Brite™ 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.
