3M 339 Aluminium Oxide, 80 mm Diameter, P60 Grit

This flap wheel is an abrasive rotary tool designed for surface finishing and material removal in industrial settings. It combines layered abrasive flaps to conform to contours and maintain consistent stock removal, making it suitable for high-speed handheld and machine-mounted operations in automation, electronics and mechanical environments.

• Aluminium oxide abrasive delivers controlled cut and longevity • P60 grit provides moderate material removal and surface refinement • Operates safely up to 9500 r/min for Rapid processing • 6mm shank allows secure mounting in common collets • 30mm face offers stable contact for flat and slightly contoured surfaces

• Suitable for deburring and blending weld seams on metal components • Ideal for preparing surfaces prior to coating in production lines • Used with rotary tools for panel edge finishing in electrical enclosures • Can be used for smoothing machined parts in automated cells • Suitable for point finishing on electronic chassis and brackets

Aluminium oxide is employed for its balance of cut rate and lifespan, making it appropriate for ferrous materials common in industrial work.

The 6mm shank is compatible with standard collets and chucks, enabling integration with many handheld and bench-mounted rotary systems.

At 9500 r/min the tool delivers intensive material removal while requiring correct dressing and steady feed to avoid overheating or uneven wear.

P60 grit is positioned for intermediate grinding where both stock removal and surface preparation are required before finer finishing steps.
