Available in sizes to fit today's most popular right angle grinding machines, abrasive flap discs are a great choice to sand, grind and remove rust and paint from metal surfaces. These flap wheels are used for removing large amounts of material and for shaping or smoothing wood, metal, and masonry. The ultra-tough zirconium oxide grain also makes these discs perfect for more aggressive applications like removing welds and finishing of ferrous and non-ferrous material. Designed for right angle grinder applications ranging from heavy stock removal to surface blending.
