3M 339 Aluminium Oxide, 50 mm Diameter, P60 Grit

This flap wheel is a rotating abrasive tool designed for surface finishing and material removal on metal components within electrical, electronics, mechanical and automation settings. It combines layered abrasive flaps for conformable contact and is intended for attachment to rotary handheld or bench-mounted tools where controlled stock removal and surface blending are required.

• Aluminium oxide abrasive delivers consistent cutting performance • Grit P60 achieves moderate material removal rates • 15,200rpm maximum safe speed permits high-speed operation • 6mm shank enables compatibility with die grinders and small rotary tools • 10mm face provides narrow access for detailed finishing

• Suitable for deburring machined steel components • Ideal for surface blending on metal chassis and enclosures • Used with die grinders for edge profiling and clean-up • Can be used for polishing weld seams in fabrication

It uses aluminium oxide, a Durable abrasive suited to ferrous Metal Work for predictable wear and cutting action.

The tool fits devices accepting a 6mm shank, commonly found on die grinders and collet-equipped rotary tools.

Operators must not exceed the 15,200rpm safe limit to maintain wheel integrity and avoid failure.

The P60 grit provides medium-coarse action, balancing Rapid material removal with a finish suited for subsequent finer sanding or polishing.
