3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Cutting Disc, 152.4 mm, 80 Grade, 50 Grit

This adhesive-backed/PSA sanding disc is a cloth-backed abrasive designed for heavy stock removal and finishing in industrial sanding operations. It uses a precision-shaped grain to sustain cutting action and an open-coat structure to resist loading, making it suitable for work on metals, wood and composite substrates where effective dust management and long disc life are required.

• Precision-shaped grain delivers fast cutting and extended life
• Open-coat construction reduces loading for consistent performance
• Anti-static treatment helps control electrically charged swarf
• J-weight cloth backing balances wear resistance with flexibility
• Hookit attachment enables rapid, secure disc changes
• Proprietary multi-hole pattern improves dust extraction efficiency

• Suitable for heavy stock removal from aluminium panels
• Ideal for blending and final finishing of hardwood surfaces
• Used for preparing composite and gelcoat prior to bonding
• Can be used for metal finishing in mechanical assembly lines
• Suitable for use with random orbital sanders fitted with vacuum

It uses a J-weight cloth backing which combines wear resistance with the flexibility needed for contour sanding.

The multi-hole pattern is designed to work with vacuum-backed pads to extract dust and reduce loading when paired with an extraction system.

The precision-shaped grain continually fractures to expose Sharp cutting edges, improving performance on metals, woods and composites during heavy removal.

An anti-static treatment neutralises the static generated by sanding, reducing clinging swarf on the disc, workpiece and equipment.

A hook-on adhesive-backed PSA system enables fast fitting and replacement of the self-adhesive 150mm disc.
