Professional Flap Disc for High Stock Removal on Steel and Stainless Steel

Supply Solutions Group supplies the Klingspor SMT 624 Supra Flap Disc (Product Code 322760) to organisations operating across metal fabrication, engineering, manufacturing, mining, construction, automotive, maintenance and industrial workshops throughout Australia.

Manufactured by Klingspor, the SMT 624 Supra Flap Disc is a premium Supra Performance Class abrasive mop disc engineered for aggressive grinding, weld dressing and surface finishing on steel and stainless steel. Featuring self-sharpening zirconia alumina abrasive grain mounted on a durable glass fibre backing plate, the disc delivers an excellent combination of high stock removal, long service life and consistent grinding performance. It is specifically designed for demanding professional applications where productivity and durability are essential.

The 100mm diameter, 16mm bore and convex 12° profile make this flap disc ideal for edge grinding, weld seam removal, chamfering and working on smaller surfaces. The convex design concentrates grinding pressure where it is needed most, providing faster material removal while maintaining operator comfort. Rated for a maximum operating speed of 15,300 RPM (80 m/s), the SMT 624 Supra is suitable for use with compatible 100mm angle grinders.

Ideal for fabrication workshops, structural steel manufacturers, stainless steel fabricators and industrial maintenance teams, the SMT 624 Supra reduces the need for multiple abrasive changes by combining grinding and finishing into a single operation.

As an Indigenous-owned industrial supplier and procurement partner, Supply Solutions Group provides genuine Klingspor abrasive products backed by responsive customer service, procurement support and Australia-wide delivery.
