Scotch-Brite™ Deburr & Finish PRO Combi Flap Brush, DB-FB, 6CMedium+/80+, 3-1/2 in x 4 in x 1-1/4 in, 1 ea/Case

Two in One

Scotch-Brite™ Deburr & Finish PRO Combi Flap Brush utilizes the benefits of high-performance coated abrasives and open-web non-woven abrasives. Fusing these abrasive characteristics together enables the brush to cut and finish in one step. Commonly used in metal fabrication industries, these brushes work well on a variety of metals. They are used to blend surfaces defects and generate grained finishes after weld removal for stainless steel and aluminum fabrication.

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 (PSG) 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 result is that 3M PSG products outcut and outlast conventional ceramic industrial abrasive products, maximizing productivity and minimizing operator fatigue.

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 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 may enhance productivity while reducing the need for cleaning chemicals and wire brushes. From aesthetic finishing to weld blending, deburring, and more, Scotch-Brite™ abrasives work fast and deliver consistent results, part after part.
