Flap Sanding Disc Rockforce RF-FD640Q 150x22.2 mm P40

Flap sanding disc Rockforce RF-FD640Q 150x22.2 mm P40 is a coarse abrasive accessory designed for aggressive material removal and surface preparation. The disc features overlapping abrasive flaps arranged radially to provide progressive cutting action and consistent wear. It is intended for use on metal, wood and painted substrates and fits angle grinders with a 22.2 mm arbor. The P40 grit delivers fast stock removal while maintaining a predictable surface finish for subsequent processing.

Advantages

The lamellar flap design gives a balance between cutting speed and flap flexibility, allowing efficient removal of rust, paint and weld seams without excessive vibration. Even wear across the disc length extends usable life and reduces the need for frequent disc changes. The standard 150 mm diameter combined with a 22.2 mm bore ensures compatibility with many common angle grinders, and the coarse P40 grit is suitable for initial shaping and heavy-duty grinding tasks.

Suitable for

• Removing rust and old paint from metal surfaces
• Shaping and leveling wooden workpieces
• Blending weld seams and smoothing metal edges
• Preparing painted surfaces for repainting or coating

Key specifications

• Diameter: 150 mm
• Bore/arbor fit: 22.2 mm
• Abrasive grit: P40 (coarse)
• Construction: overlapping abrasive flaps (lamellar)
• Compatible tool: angle grinder (disc type)

How to use

Mount the flap sanding disc securely on an angle grinder with a 22.2 mm arbor according to the tool manufacturer's instructions. Use appropriate rotational speed recommended for flap discs and maintain a steady, even pressure while moving the disc across the workpiece. For metal work, keep the disc moving to avoid localized overheating; for wood, adapt pressure to achieve the desired level of stock removal without gouging. Replace the disc when the flaps are worn down or cutting efficiency decreases.

Usage recommendations

Always use suitable personal protective equipment, including eye protection, gloves and hearing protection. Verify that the grinder's maximum RPM is compatible with the flap disc's rated speed. For best results on painted or coated surfaces, start with P40 for initial removal and follow with finer grits as needed for surface refinement.
