3M Adhesive-Backed/PSA Sanding Disc, 150mm Disc Diameter - 7100284769

This adhesive-backed/PSA sanding disc is a 150mm abrasive disc designed for heavy stock removal and finishing in industrial settings. It combines precision-shaped mineral for Rapid cutting with a Durable cloth backing to withstand demanding use. The product is intended for powered orbital sanders with vacuum extraction and is suited to materials including metals, timber and composite substrates.

Features & Benefits

• Precision-shaped grain provides Faster cutting and extended life
• Open coat construction reduces loading and sustains cut rate
• Anti-static treatment helps control electrically charged swarf
• J-weight cloth backing balances wear resistance with flexibility
• PSA attachment allows quick adhesive hook-and-loop replacement
• Proprietary multi-hole pattern improves dust extraction efficiency

Applications

• Suitable for heavy stock removal on aluminium components
• Ideal for blending and finishing hardwood and softwood panels
• used with orbital sanders for composite and gelcoat work
• Suitable for metal fabrication deburring and surface prep

What backing material supports repeated abrasive use?

A J-weight cloth backing gives durability and conforms during aggressive sanding without tearing, helping maintain consistent cut across varied contours.

How does dust management perform when connected to extraction?

The disc’s multi-hole configuration is engineered for enhanced dust extraction, which reduces loading and helps maintain abrasive performance when used with an effective vacuum system.

Can the disc handle both rough removal and fine finishing?

The abrasive geometry is effective across grades

coarse grades remove substantial material while finer grades are suitable for blending and finishing aluminium and timber.

How does the anti-static treatment affect workshop cleanliness?

The treatment reduces static charge on swarf so particles are less likely to cling to the disc, workpiece or machinery, aiding in cleaner extraction and fewer interruptions.
