3M, 203.2 mm

This adhesive-backed/PSA sanding disc is a 203mm abrasive disc engineered for heavy stock removal and finishing tasks across wood, metals and composites. It uses precision-shaped grain to maintain cutting edges as the grain fractures, and a cotton cloth backing for flexibility and wear resistance. The product is designed for use with vacuum extraction systems to reduce airborne dust and swarf during powered sanding operations.

• Precision-shaped grain delivers fast cutting and extended life
• Open coat construction reduces loading for sustained cut rate
• Anti-static treatment helps control electrically charged swarf
• Cotton cloth backing combines durability with conformability
• PSA attachment enables quick, secure mounting and replacement
• Multi-hole extraction option improves dust removal efficiency

• Suitable for heavy stock removal on aluminium panels and components
• Ideal for surface preparation of fibreglass and gelcoat parts
• Used for blending and finishing hardwood and softwood surfaces
• Can be used for deburring and smoothing metal assemblies
• Suitable for orbital sanders paired with vacuum back-up pads

The mineral fractures in a controlled manner to expose fresh, Sharp edges, preserving cut rate and consistency over extended use.

It reduces static charge on dust and swarf so particles are less likely to cling to the disc, workpiece or machinery, improving dust collection effectiveness.

The cotton cloth backing offers a balance of wear resistance and flexibility, allowing the disc to follow contours while resisting abrasion during heavy-duty sanding.

Pair with a multi-hole back-up pad and a random orbital Sander fitted to a vacuum collection system to capture extraction through the disc pattern.
