The Sigma Screen is an all-purpose flexible mesh depressed center Type 27 abrasive wheel for removing light welds, burrs, rust and paint. The wheel features a blend of zirconia-ceramic abrasive grains bonded to a flexible mesh for grinding, blending and finishing applications. Much more flexible than resin-fiber discs, these mesh wheels are cool-running, chatter-free and do not clog. Suitable for industrial fabrication and maintenance applications, the wheel is 4.5 inches in diameter; and available with coarse, medium and fine grits. Several can be stacked onto a grinder and they can be used on stainless steel, metals, aluminum, composites and wood.
