3M Adhesive-Backed/PSA Sanding Disc, 125mm Disc Diameter, 150+ Grade - 7100284353

This adhesive-backed/PSA sanding disc is a 125mm cloth abrasive designed for heavy stock removal and finishing in industrial settings. It combines precision-shaped mineral for a consistent cutting action with a flexible, wear-resistant J-weight cloth backing and is intended for use where effective dust management and sustained cutting performance are required.

Features & Benefits

• Precision-shaped grain delivers fast cut and extended life
• Open coat design resists loading for sustained throughput
• Anti-static treatment reduces static cling of swarf
• Hookit-compatible PSA speeds disc changes and uptime
• J-weight cloth backing balances durability and flexibility

Applications

• Suitable for Rapid material removal on aluminium panels
• Ideal for blending and finishing hardwood and softwood
• Used for sanding composites, gelcoat and fibreglass surfaces
• Can be used with vacuum-equipped random orbital sanders
• Suitable for metalworking tasks in production environments

How does dust extraction performance assist workshop productivity?

When paired with a multi-hole back-up pad and vacuum, the disc’s extraction pattern helps prevent loading, aiding consistent cut rate and reducing downtime for cleaning.

What benefit does the anti-static treatment provide during sanding?

It neutralises the charge generated on wood and other substrates, reducing adherence of electrically charged swarf to the disc, workpiece and machinery which helps maintain abrasive efficiency.

Which materials will maintain disc performance without premature clogging?

The open coat construction is effective on materials prone to loading, such as softwoods, aluminium and resin-rich composites, preserving cutting action.

How does the cloth backing affect handling and wear?

The J-weight cloth backing offers a combination of wear resistance and flexibility that supports consistent contact on contoured parts while tolerating production use.

Can the discs be used on powered grinders?

They are compatible with 125mm grinders and random orbital sanders when used with the correct PSA back-up pad and extraction setup.
