Flap Disc 125 mm, 100 Grit, Flat, Expert+ – pack of 10

Flap Disc 125 mm, 100 Grit, Flat, Expert+ – pack of 10 is a flat (type 27) abrasive flap disc designed for use with handheld angle grinders. With a 125 mm diameter and 100 grit abrasive, this flap disc is intended for medium-to-fine material removal and surface finishing on metal and stainless steel. The pack of 10 provides a convenient supply for workshop tasks such as rust and paint removal, deburring, light grinding and shaping, combining abrasive flaps mounted on a reinforced backing for consistent performance and longer life compared to single-layer abrasives.

Advantages

The flap disc construction delivers even wear and sustained cutting action, reducing the need for frequent disc changes. Its flat type 27 profile offers stable contact with the work surface for controlled material removal and uniform finish. The 100 grit abrasive balances material removal rate and surface refinement, making it suitable for both stock removal and pre-finishing. Supplied in a pack of 10, the discs are practical for professionals and hobbyists who require multiple replacements during extended projects.

Suitable for

• Sanding and finishing of steel and stainless steel surfaces
• Removal of rust, scale and paint
• Deburring edges after cutting or welding
• Light grinding and shaping of metal parts
• Surface preparation before welding or painting

How to use

Ensure the angle grinder is switched off and unplugged before fitting the flap disc. Mount the disc according to the grinder manufacturer’s instructions, check that the disc is secure and free of damage, and wear appropriate personal protective equipment including eye protection, gloves and hearing protection. Start the grinder and allow it to reach full speed before applying the disc to the workpiece. Use moderate pressure and maintain a consistent angle to the surface to avoid gouging; move the disc across the workpiece in controlled passes until the desired finish or material removal is achieved. After use, inspect the disc for wear or damage and replace when abrasive performance decreases or the backing is compromised.

Usage recommendations

Use the 100 grit flap disc for balanced removal and finishing tasks; for heavier material removal choose a coarser grit, and for finer polishing switch to a higher grit. Maintain proper disc speed and avoid excessive side pressure to prolong disc life. Store discs in a dry, temperature-stable environment to prevent backing deformation and adhesive breakdown.
