Flap Disc KLINGSPOR Ø125 mm, 22 mm bore, Grit 40 — KL321690, 1 pc

Flap Disc KLINGSPOR Ø125 mm, 22 mm bore, Grit 40 is a single-piece abrasive disc designed for use with angle grinders. It combines overlapping abrasive flaps bonded to a rigid backing to deliver aggressive material removal while maintaining control over the finished surface. Intended for metalworking and general-purpose grinding, this flap disc performs tasks such as weld removal, deburring, rust and paint preparation, and shaping of workpieces.

Advantages

The flap construction provides consistent cutting action with reduced vibration compared to conventional grinding wheels, enabling smoother operation and predictable wear. A 40-grit abrasive offers a balance between stock removal and surface blending, while the 125 mm diameter and 22 mm bore fit common angle grinder sizes for versatile application. The rigid backing supports even pressure distribution, improving safety and life of the disc during repetitive use.

Suitable for

• Removing weld seams and smoothing weld beads on steel and stainless steel
• Deburring and edge blending on sheet metal and fabricated parts
• Surface preparation prior to painting or coating by removing rust and old paint
• Shaping and contouring of metal components and profiles

Key specifications

• Disc diameter: 125 mm
• Bore (arbor) size: 22 mm
• Abrasive grit: 40 (coarse)
• Single-piece flap design with rigid backing for controlled removal
• Suitable for use on metal and various other materials with an angle grinder

How to use

Mount the flap disc on a compatible angle grinder with a 22 mm arbor and ensure the grinder is disconnected from power while fitting. Check that the disc is free of visible damage and that the backing flange is appropriate for the disc diameter. When operating, hold the grinder with both hands and apply moderate, even pressure; allow the abrasive flaps to do the cutting rather than forcing the disc. Work across the surface with smooth, overlapping passes to achieve uniform material removal and to avoid gouging. After use, inspect the disc for wear or damage and replace when the abrasive becomes ineffective or the backing is compromised.

Usage recommendations

For best results on steel and stainless steel, use the 40-grit flap disc for initial stock removal and weld blending, then follow with finer abrasives for finishing. Always wear appropriate personal protective equipment including eye protection, hearing protection, gloves, and respiratory protection when grinding. Adhere to the angle grinder's maximum RPM rating and the disc's speed limits.
