3M 7100177539 | Aluminum Oxide Coarse Sanding Star

Scotch-Brite star was designed for blending, deburring and finishing hard-to-reach internal diameters, including metal tubing and piping.

• Scotch-Brite star has six spindles attached to an eyelet. Made with nonwoven technology, the spindles are spongy, buoyant and flexible. Consequently, they can bend and move to accommodate the insides of metal tubes and pipes. Scotch-Brite Star comes in small sizes, with the smallest diameter being 1-1/2" and the largest diameter being 4". The small size supplements the spongy spindles, helping the abrasive fit inside hard-to-reach areas. These stars lightly deburr and blend contours and ridges without gouging or marring the surface, helping to reduce scraps and rework. Stars may be used on a variety of metals: stainless steel, aluminum, carbon steel, cast iron, titanium and non-ferrous metals.

• The Scotch-Brite star may be used with 3M mandrel 944. The threaded attachments fasten to mandrel 944 for safe use on a die grinder. Scotch-Brite star requires low pressure when used at correct operating speeds. The abrasive is available in coarse (CRS) and very fine (VFN) grades. Use a coarse abrasive when refining a deep grind line/scratch or when a more aggressive scratch pattern is desired, and use a fine abrasive when a soft, fine scratch pattern is desired.

• Nonwoven technology makes the 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 not only enhance productivity, but also increase operator safety. By reducing the need for cleaning chemicals and pastes, and replacing wire brushes that can break off and cause injury. From aesthetic finishing to deburring and more, Scotch-Brite abrasives work fast and deliver consistent results, part after part.

Features:

• Open web is load resistant, prolonging abrasive service life
• May be used with 3M mandrel 944 for easy fastening and attachment to abrasive tools
• Spring-like action of spindles permits abrasive to bend easily and fit inside hard-to-reach areas
