3M 7100045070 Aluminium Oxide Surface Conditioning Disc Abrasive Disc, 127 mm, 80 Grade, 80+ Grit

This abrasive disc is designed for surface conditioning tasks in industrial sanding and grinding environments. It combines a tough aluminium oxide abrasive with a film backing to deliver consistent material removal on metal and other hard substrates while operating at high rotational speeds.

• Aluminium oxide abrasive provides sustained cutting performance
• Film backing offers dimensional stability at high speed
• Rated to run safely at 12,000 r/min for high-speed operations
• 80 grade abrasive balances cut rate with surface finish
• Compatible with surface conditioning workflows for efficient prep

• Suitable for metal deburring and edge-blending operations
• Ideal for preparatory sanding before coating or welding
• Used with high-speed pneumatic or electric sanders
• Can be used for finishing stainless and mild steel components

The grain is aluminium oxide, selected for effective abrasion on ferrous metals and similar hard materials.

The film backing maintains disc flatness under centrifugal forces, reducing vibration and improving consistency during prolonged runs.

The abrasive is 80 grade, which delivers moderate material removal while producing a controlled surface texture suitable for subsequent processes.

It is optimised for high-speed surface conditioning rather than low-speed fine polishing, given its abrasive composition and backing design.
