Achieve fast stock removal and a consistent surface finish with the Klingspor SMT 624 Supra Flap Disc, a premium 100mm × 16mm flap disc engineered for demanding grinding applications on steel and stainless steel. Featuring 60 grit self-sharpening zirconia alumina abrasive and a 12° convex profile, this professional-grade flap disc delivers an excellent balance of aggressive material removal, long service life and smooth grinding performance. Designed for use with 100mm angle grinders, the 322760 is ideal for fabrication, engineering, welding, construction, mining and industrial maintenance applications.

Manufactured using premium zirconia alumina abrasive cloth mounted on a high-strength glass fibre backing plate, the SMT 624 Supra continuously exposes fresh cutting edges during use for consistent grinding performance and extended disc life. The 12° convex design makes it particularly effective for grinding weld seams, chamfering edges and working on contoured surfaces where higher stock removal is required. The durable fibre backing provides excellent stability while reducing vibration for improved operator comfort and safety.

Designed for professional metalworkers and fabricators, the SMT 624 Supra eliminates the need for frequent wheel changes by combining grinding and finishing in a single operation. Whether preparing welds, deburring fabricated components or blending edges on stainless steel and mild steel, it delivers dependable performance and a uniform scratch pattern for reduced rework.
