3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 76.2 mm, 180+ Grade, 180 Grit

This adhesive-backed/PSA sanding disc is a precision abrasive designed for heavy stock removal and finishing in industrial sanding operations. It combines shaped ceramic grain with a Durable cotton cloth backing and an adhesive hook-and-loop compatible attachment to support high-throughput sanding when paired with dust extraction systems. The product is engineered for use across wood, metals and composite substrates where consistent cutting action and reduced disc changes are required.

• Precision-shaped grain delivers Rapid material removal and extended life
• Anti-static treatment reduces charged swarf accumulation during sanding
• Open-coat construction prevents loading and maintains cutting performance
• Cotton cloth backing offers wear-resistance while remaining flexible
• 3M Xtract multi-hole pattern improves dust extraction and reduces clogging

• Suitable for heavy stock removal on aluminium panels
• Ideal for surface preparation in automotive finishing workflows
• Used for sanding composite components in electronics enclosures
• Can be used for blending and finishing hardwood and softwood edges
• Suitable for metal deburring and panel smoothing in mechanical assemblies

It uses a cotton cloth backing with an adhesive/PSA system compatible with Hookit-style back-up pads for quick disc changes.

The shaped grain fractures to expose fresh cutting edges, producing even wear and prolonged abrasive life compared with conventional minerals.

Performance is optimised when used with a vacuum-equipped random orbital Sander and the multi-hole back-up pad to capture debris and reduce loading.

The 180+ grit specification is suitable for metal finishing tasks and for blending on aluminium, hardwoods and composite surfaces.
