3M 339 Series Flap Wheel, 80mm Diameter, 50mm Face Width - FC110075916


This flap wheel is an abrasive rotary tool designed for surface conditioning and material removal in industrial settings. It uses aluminium oxide abrasive to abrade and blend surfaces while mounted on rotary equipment. The product suits operations requiring a compact, high-speed abrasive solution compatible with hand-held or machine-driven spindles.

Features and Benefits:


• P60 abrasive grit balances stock removal with surface finish
• 9,500 rpm maximum safe speed enables Rapid material removal
• 6mm shank permits direct mounting in common collets and chucks
• 50mm face width covers a broader surface area per pass
• Aluminium oxide construction offers Durable cutting performance

Applications


• Suitable for deburring machined metal edges
• Ideal for surface blending on fabricated components
• Used for preparing joints prior to inspection or assembly
• Can be used for dressing weld seams in production lines
• Used with portable spindles in electronics and electrical workshops

What shaft size is required for mounting?


It fits into tool holders accepting a 6mm shank and can be clamped in standard collets and micro-drills designed for that diameter.

How should maximum rotational speed be interpreted for safe operation?


Operate below the specified 9,500 rpm ceiling to maintain the integrity of the abrasive and avoid imbalance-related hazards.

Which abrasive material is used and what does it imply for longevity?


The media is aluminium oxide, chosen for its abrasive hardness and general-purpose durability on ferrous and non-ferrous substrates.

What face coverage can be expected per pass?


The wheel presents a 50mm working face, enabling a wider contact area than narrow wheels for efficient Planar finishing.
