3M 339 Aluminium Oxide, 60 mm Diameter, P60 Grit

This flap wheel is a rotating abrasive tool designed for material removal and surface finishing on metal components when mounted in a handheld or machine-driven grinder. It is constructed with layered abrasive flaps and a central shank that fits into power tools, providing controlled stock removal and surface conditioning at elevated rotational speeds for tasks common in automation, electronics, electrical and mechanical settings.

• Aluminium oxide abrasive delivers consistent cutting action • P60 grit balances stock removal and surface refinement • 12,700 rpm maximum speed enables high-rate metalworking • 6mm shank ensures secure mounting in compatible chucks • 15mm face width concentrates abrasion for focused finishing

• Suitable for deburring machined steel edges • Ideal for blending weld seams on fabricated parts • Used with handheld grinders for panel preparation • Can be used for smoothing castings prior to assembly • Used for removing scale and oxidation from metal surfaces

The abrasive is aluminium oxide, which provides Durable cutting on ferrous alloys and maintains abrasive life under heat generated during metalworking.

The 15mm face concentrates abrasive action, making it appropriate for targeted finishing and confined areas where broader discs would be unsuitable.

A 6mm shank is specified, so use a grinder or spindle accepting that diameter to ensure firm retention and minimise runout.

Operate below the 12,700 rpm maximum safe speed to avoid mechanical overload and ensure the assembly functions within its rated dynamic balance.

The P60 grit offers a medium-coarse cut rate suitable for initial surface levelling and preparatory finishing without over-polishing.
