3M Scotch-BriteTM Precision Heavy Duty Aluminium Oxide Surface Conditioning Disc Hook & Loop Sanding Disc, 4 in, Coarse

This hook & loop sanding disc is a coarse non-woven abrasive designed for heavy-duty surface conditioning in industrial settings. It combines aluminium oxide mineral with a conformable non-woven web to perform deburring, blending and light grinding on metallic components while preserving part profile. The product suits operators in automation, electronics, electrical and mechanical sectors requiring consistent cut and extended life at elevated spindle speeds.

• Aluminium oxide mineral delivers aggressive material removal and longevity
• Non-woven web backing reduces gouging while maintaining surface finish
• Centre hole design allows reliable mounting on backed pads
• Rated maximum safe speed 15,000 r/min for high-speed applications

• Suitable for deburring machined mild steel components in automation
• Ideal for edge breaking on electrical enclosures and panels
• Used for blending weld seams on mechanical assemblies
• Can be used for finishing aluminium housings in electronics fabrication
• Suitable for use with hook and loop backed pads and quick-change systems

They are designed for hook & loop attachment and centre-hole mounting on compatible back-up pads and quick-change systems.

The conformable non-woven web maintains shape at edges, helping retain profile and reducing the risk of undercutting during aggressive work.

It performs well under high-pressure, heavy-duty tasks where continuous material removal is required on ferrous and non-ferrous metals.

Discs are packaged in bulk as a 100-pack to support high-volume usage and minimise replenishment frequency.
