Klingspor 322783 SMT 624 Flap Disc, 180 x 22.23 mm, Grit 40, Conical, 10 Pieces

Aggressive stock removal on steel and stainless steel demands a flap disc that cuts fast, resists loading, and lasts through heavy use. The Klingspor SMT 624 conical flap disc with zirconia alumina grit 40 delivers high material removal on angle grinders, especially on contoured surfaces and weld seams.

Who is it for

Metal fabricators, welders, and maintenance crews who need a durable 180 mm flap disc for grinding and blending steel and stainless steel. The conical shape reaches into corners and follows curves better than flat discs.

Main features
