LUKAS grinding flap disc 125 x 13 x 22.3 mm fiberglass A270112500114

LUKAS grinding flap disc 125 x 13 x 22.3 mm with a fiberglass backing is a multi-purpose abrasive wheel intended for use on standard angle grinders. The disc features overlapping abrasive flaps that deliver controlled material removal, blending and deburring on workpiece surfaces. Its 125 mm diameter and 22.3 mm bore make it compatible with many common grinders, and the fiberglass backing provides a balance of stiffness and resilience for stable grinding performance.

Advantages

The flap construction ensures consistent wear and uniform cutting action, maintaining performance over the life of the disc. The fiberglass backing improves durability and reduces vibration compared with thin fibre variants, resulting in smoother surface finishes. The disc is designed for efficient stock removal while allowing a level of finish suitable for follow-up operations such as polishing or painting.

Suitable for

• Metal surface grinding and finishing
• Deburring welded joints and edges
• Blending and smoothing rough surfaces
• General-purpose abrasive tasks with a 125 mm disc

Key specifications

• Diameter: 125 mm
• Thickness: 13 mm
• Bore diameter: 22.3 mm
• Backing material: fiberglass
• Construction: overlapping abrasive flaps
• Intended tool: angle grinder compatibility

How to use

Mount the flap disc on a compatible angle grinder with the correct arbor size and ensure the grinder is switched off before installation. Inspect the disc for damage before use and secure any safety guards. Operate the grinder at the manufacturer's recommended speed range and apply moderate pressure, allowing the abrasive flaps to cut without forcing the tool. Move the disc evenly across the workpiece to avoid gouging and maintain consistent contact angle for uniform results. Replace the disc when wear reduces cutting efficiency or when structural damage is visible.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and hearing protection. Ensure the workpiece is securely clamped and avoid side-loading the disc beyond its intended use. Store the disc in a dry environment away from extreme temperatures to preserve abrasive performance.
