Flap Brushes: Scotch-Brite™ High Strength Premium Blend and Finish Flap Brush

Our Scotch-Brite™ High Strength Premium Blend and Finish Flap Brush is one of 3M's best-performing flap brushes. It provides greater durability, longer life and exceptional finish, while running soft, smooth and smear free.

  • Flap construction helps minimize chatter risk
  • Available in a variety of grades, so operators can choose the right brush for their unique application
  • Aluminum Oxide mineral cuts sharp but leaves a soft scratch pattern
  • Open web is spongy and responsive, minimizing risk of altering part geometry
  • Open web is load resistant, helping to prolong abrasive service life

The Anatomy of Flap Brushes

We engineer the Scotch-Brite™ High Strength Premium Blend and Finish Flap Brush by adhering individual sheets of abrasive material to a fiberglass core at a 90 degree angle. As it 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. The brush may be used with a variety of tools, including backstand, match and finish sander and a centerless grinder. 

Available in a Variety of Grades

Our Scotch-Brite™ High Strength Premium Blend and Finish Flap Brush combines aluminum oxide mineral and non-woven nylon fibers using resin. The mineral is available in a variety of grades, so operators may choose the right grade for their particular application. Grades include: CRS, MED and VFN. Typically, a coarser grade is desirable when operators seek a more aggressive cut. Contrarily, a very fine grade is desirable when a softer scratch is desirable. We also offer this brush in Type L (Lofty) for the coarse and medium grades, for greater conformability.

Independent of the grade chosen, operators will get the same level of consistency and responsiveness they've come to expect from Scotch-Brite™ abrasives. Each brush offers unique cleaning or finishing capabilities based on different grade and density combinations.

Common Applications

Our High Strength Premium Blend and Finish Flap Brush helps with blending finishes, deburring and antique finishing on hardware and plumbing fixtures. 

Scotch-Brite™ Flap Brushes are used by manufacturers of hand tools, surgical equipment, stamped metal parts, transportation vehicles, builders hardware, plastic products, mouldings and woodworking products. Aerospace component manufacturers condition surfaces of blades, vanes, rotors, fasteners, nozzles, extrusions and airframe supports. In maintenance and repair, Scotch-Brite flap brushes are used to clean and condition surfaces properly and efficiently. Although these are not required for most applications, most common industrial grinding lubricants, coolants, and/or compounds can be used with Scotch-Brite™ flap 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. From aesthetic finishing to weld blending, deburring, and more, Scotch-Brite abrasives work fast and deliver consistent results, part after part.
