3M 7100045070 Series Abrasive Disc, 127mm Disc Diameter, 80 Grit Size - 7100045070

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.

Features and Benefits:

• 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

Applications

• 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

What substrate is the abrasive suited to?

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

How does the backing influence performance?

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

What grade is provided and what does it mean for finish?

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

Is the disc intended for low-speed polishing tasks?

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