Klingspor 322783 SMT 624 Disco de lixa de lamelas, 180 x 22,23 mm, grão 40, cónico, 10 unidades

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

• Zirconia alumina abrasive grain for high stock removal and long life on metal.
• Conical (gewölbt) shape for grinding on angled surfaces and edges.
• Fiberglass backing plate for stability at high speeds.
• Resin over resin bonding for strong grain adhesion and cool cutting.
• Outer diameter 180 mm, bore 22.23 mm, fits standard angle grinders.
• Maximum operating speed 80 m/s (8500 RPM).
• Pack of 10 discs.
