Flap Disc KLINGSPOR SMT624 SUPRA 125 mm grit 36 (MPN 322771)

Flap Disc KLINGSPOR SMT624 SUPRA 125 mm grit 36 is a convex abrasive disc made of overlapping abrasive flaps designed for material removal, deburring and surface preparation on metal. Intended for use with angle grinders that accept 125 mm attachments, this flap disc delivers consistent cutting action and an even finish on welds, edges and flat surfaces. The coarse 36 grit provides relatively aggressive stock removal while maintaining control over the workpiece surface.

Advantages

The KLINGSPOR SMT624 SUPRA combines a durable backing plate with layered abrasive flaps to ensure uniform wear and extended life compared with single-layer abrasives. The convex shape improves contact conformity on angled and contoured surfaces, enabling predictable material removal. Coarse grit ensures efficient grinding of welds, rust and scale while reducing the frequency of disc changes during workshop operations.

Suitable for

• Grinding and shaping weld seams on steel and stainless steel
• Deburring cut edges and removing sharp burrs
• Surface preparation before painting or coating
• Rust, scale and old coating removal on metal parts
• General stock removal and leveling of flat and slightly contoured surfaces

Key specifications

• Disc diameter: 125 mm
• Grit size: 36 (coarse)
• Disc shape: convex, overlapping abrasive flaps
• Intended tool: angle grinder with 125 mm mounting
• Material compatibility: steel, stainless steel and other common metals
• Typical use: metal grinding, deburring, surface preparation

How to use

Mount the flap disc on an angle grinder specified for 125 mm discs following the tool manufacturer's mounting instructions and safety guidelines. Operate the grinder at the recommended speed range for the disc and apply moderate, even pressure; allow the abrasive flaps to do the cutting rather than forcing the disc into the workpiece. Move the disc steadily along welds, edges or surfaces to achieve uniform material removal and avoid dwell in one spot to prevent overheating or gouging.

Usage recommendations

Wear appropriate personal protective equipment including eye, face and hearing protection, gloves and respiratory protection when grinding. Match the disc grit to the task: use grit 36 for aggressive stock removal and initial shaping, then follow with finer grits for smoothing and finishing. Inspect the disc before use for damage or uneven wear and replace when flap wear reduces effectiveness or backing is exposed.
