3M Aluminium Oxide Abrasive Disc Surface Conditioning Disc, 125 mm, Extra Coarse Grade

This abrasive disc is designed for surface preparation and material removal in industrial settings. It employs aluminium oxide abrasive to tackle heavy stock removal and conditioning tasks, and is intended for use where electrostatic-sensitive handling is required under ANSI/ESD S20.20:2021 protocols.

• Extra coarse grade for Rapid material removal and shorter cycle times
• Surface conditioning construction delivering consistent finish across batches
• Compatible with 100mm tooling for common rotary and orbital systems
• ESD-safe formulation enabling safer work on sensitive electronic components
• Manufactured by an established abrasives brand for supply-chain consistency

• Suitable for metal finishing prior to welding or coating
• Ideal for preparing chassis and frames in mechanical assemblies
• Used for deburring heavy-gauge components in automation equipment
• Can be used for panel surface treatment in electrical enclosures
• Used with ESD workstations for electronics manufacturing prep

The aluminium oxide abrasive cuts aggressively on stainless steel, producing fast stock removal while producing an even conditioned surface suitable for subsequent processing.

The disc meets ANSI/ESD S20.20:2021 guidelines, so when used within an ESD-controlled environment it helps reduce charge accumulation during handling and operation.

It is compatible with standard 100mm fastening systems commonly found on rotary and random-orbit machines, enabling secure mounting and stable operation.

The extra coarse grade reduces the number of passes required to reach target geometry, decreasing cycle time on heavy stock-removal tasks.
