3M Adhesive-Backed/PSA Sanding Disc, 150mm Disc Diameter, Cloth Backing - 7100284530

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.

Features & Benefits

• 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

Applications

• 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

What backing material supports durability and flexibility?

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

How does the disc manage dust during 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.

Which materials benefit most from the abrasive grain design?

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

How is static charge addressed when working on timber?

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

What attachment method is used for quick changes?

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