This range of abrasive flap discs are ideal for applications where high removal rates are needed on edges, weld seams and other small surfaces. When used with powerful angle grinders, this abrasive disc excels and demonstrates its aggressive removal rate while also being easy to use. The zirconia alumina ensures the disc has a long service life through self-sharpening, forming new edges throughout the grinding process. Features and Benefits Excellent stability and durability Consistent high performance Arrangement of grinding flaps ensures long service life Zirconia alumina grain ensures excellent abrasive performance Typical Applications Steel Stainless steel Edge and surface work Standards Break resistance that exceeds the provisions of the oSa and EN 13743 standards Klingspor 322761 SMT624 100X16MM 80 Grit Zirconium Flap Disc Abrasives, SandingAbrasives, FlapDiscs.
