Flap grinding disc 125x22 mm A40 GEKO (abrasive flap wheel) 125 mm diameter, 22 mm bore, A40 grit

Flap grinding disc 125x22 mm A40 GEKO is an abrasive flap wheel designed for surface grinding, deburring and edge finishing of metals and other hard materials. With a 125 mm overall diameter and a 22 mm central bore, this disc fits angle grinders and handheld grinders that accept a 22 mm arbor. The A40 abrasive grit provides medium stock removal and shaping performance suitable for common workshop and fabrication tasks, including weld seam blending and edge preparation.

Advantages

The GEKO A40 flap grinding disc combines a flexible layered abrasive construction with a medium-coarse grit grade to balance cutting speed and surface control. Its 125 mm size offers a stable working area for consistent material removal while the 22 mm bore ensures compatibility with many standard grinders. The disc is engineered to conform to contoured surfaces and edges, reducing the risk of gouging while maintaining effective deburring and blending capabilities.

Suitable for

• Surface grinding and smoothing of steel and ferrous metals
• Deburring and removal of sharp edges after cutting or machining
• Weld seam blending and cleanup in metal fabrication
• Edge finishing and light shaping of stainless steel and non-ferrous metals
• General workshop finishing and preparation before painting or coating

Key specifications

• Overall diameter: 125 mm
• Center bore: 22 mm
• Abrasive grit: A40 (medium-coarse)
• Type: abrasive flap wheel / flap grinding disc
• Typical applications: grinding, deburring, edge finishing, weld blending

How to use

Mount the 125x22 mm A40 GEKO flap grinding disc on a compatible angle grinder with a 22 mm arbor following the tool manufacturer's instructions for fitting and tightening accessories. Start the grinder at a moderate speed and apply light, even pressure while moving the disc across the workpiece to avoid concentrating heat or removing excessive material. Allow the layered flaps to do the cutting; avoid aggressive force that can shorten disc life or damage the surface. Use appropriate personal protective equipment and ensure the workpiece is securely clamped.

Usage recommendations

Use the disc for medium stock removal and finishing tasks on metals; for finer surface finishes select a higher grit number, and for heavier material removal choose a coarser abrasive. Inspect the disc before use for damage and replace if flaps are worn or detached. Observe speed ratings of both grinder and disc and maintain consistent contact to extend service life.
