3M™ Cloth Disc 577F tackles high pressure metalwork and rough grinding with ease. Fast-cutting alumina zirconia is bonded to a strong, water-resistant polyester cloth backing for stability and long life and may be run wet or dry. Extra Cutting Power for High Stock Removal Ideally suited for heavy stock removal and high pressure grinding, 3M™ Cloth Disc 577F tackles tough, high-pressure grinding jobs. Alumina zirconia is both sharp and durable, and was developed specifically for heavy stock removal and high pressure grinding. Built Strong to Last Long To back up the tough, sharp-cutting abrasive, a YF-weight polyester cloth backing offers a very stable backing. A grinding aid supersize reduces grinding temperatures for processes involving heat-sensitive alloys such as stainless steel, nickel alloys, and titanium. Recommended Applications This disc is best suited to off-hand applications like weld grinding, beveling and deburring, edge grinding, and weld seam blending, on mild steel, stainless steel, high nickel alloys and aluminum.
