3M Aluminium Oxide Abrasive Disc Surface Conditioning Disc, 178 mm, Extra Coarse Grade

This abrasive disc is a surface conditioning tool designed for heavy-duty material removal and finishing in industrial settings. Manufactured by 3M, it combines a robust fibre backing with aluminium oxide abrasive to tackle demanding metalwork and surface-preparation tasks. The disc is electrostatic-safe to align with ESD controls and is intended for use where controlled abrasion and consistent performance are required.

• Extra-coarse abrasive for rapid stock removal
• Aluminium oxide grains provide aggressive cutting action
• Fibre backing supports sustained pressure and durability
• Black colour assists visual wear assessment under lighting
• Conforms to ANSI/ESD S20.20:2021 for electrostatic safety

• Suitable for aggressive deburring of steel components
• Used for surface preparation prior to coating processes
• Ideal for weld blend and edge radiusing operations
• Can be used with rotary tools for heavy-duty sanding

The fibre backing disperses contact forces and helps resist heat-induced deformation during continuous abrasion.

The aluminium oxide abrasive offers a balance of friability and hardness, promoting consistent cutting and extended life on ferrous workpieces.

Yes, the disc meets ANSI/ESD S20.20:2021 criteria to reduce electrostatic generation during use in controlled environments.

The disc's black finish alters in texture and sheen as grains wear, providing a visual indication for timely replacement.
