Flap Disc Irwin 125 mm x 22.23 mm P60 for Wood, Metal and Plastics

Irwin Flap Disc 125 mm x 22.23 mm P60 is a general-purpose abrasive disc designed for material removal and surface finishing on wood, metal and plastics. The 125 mm diameter with a 22.23 mm bore fits standard angle grinders and the P60 grit provides medium-coarse cutting action for efficient stock removal while producing a consistent surface. The flapped abrasive construction ensures even wear and predictable finish across a variety of tasks including deburring, shaping and paint or rust removal.

Advantages

The flap disc combines overlapping abrasive flaps that deliver controlled cutting rates and longer life compared with single-layer discs. Its P60 grit balances aggressive material removal with the ability to leave a uniform finish, reducing the need for subsequent sanding steps. Compatibility with common 125 mm angle grinders and the stable 22.23 mm bore provide reliable mounting and rotational stability during operation.

Suitable for

• Grinding and shaping wood components
• Deburring and blending welds on steel and non-ferrous metals
• Removing rust and paint from metal surfaces
• Smoothing and profiling plastic parts
• Surface preparation before painting or coating

Key specifications

• Disc diameter: 125 mm
• Bore: 22.23 mm
• Abrasive grit: P60 (medium-coarse)
• Construction: overlapping abrasive flaps
• Intended substrates: wood, ferrous and non-ferrous metals, plastics

How to use

Mount the flap disc on a compatible 125 mm angle grinder with a 22.23 mm arbor, ensuring the disc is correctly seated and tightened according to the grinder manufacturer’s instructions. Operate the grinder at the recommended speed rating for the disc and apply light to moderate pressure; allow the flaps to abrade the surface rather than forcing the tool. Use steady, even passes and keep the disc moving to avoid gouging or overheating the workpiece. Replace the disc if damaged, unevenly worn, or if performance declines.

Usage recommendations

Wear appropriate personal protective equipment including eye, hearing and respiratory protection when grinding. Select P60 grit for medium stock removal; for finer finishing follow with higher-grit discs or sanding as needed. Test on a scrap piece when working with unfamiliar materials to verify cutting rate and finish quality. Store discs in a dry, cool environment to preserve abrasive integrity.
