3M Adhesive-Backed/PSA Sanding Disc, 125mm Disc Diameter - 7100284531

This adhesive-backed/PSA sanding disc is a cloth-backed abrasive designed for heavy stock removal and finishing in industrial settings. It employs precision-shaped grain to achieve fast cutting and consistent wear, and its construction is compatible with hook-and-loop or PSA attachment systems for Rapid disc changes during high-throughput operations.

Features & Benefits

• Precision-shaped grain delivers continuous fracturing for sustained cutting performance
• Cloth backing offers wear-resistance while remaining flexible for contoured surfaces
• Anti-static treatment reduces charged swarf adherence for cleaner operation
• Open coat design limits loading to maintain cut rate and extend life
• Multi-hole pattern improves dust extraction when used with a vacuum
• Suitable for use on metals and composites to speed material removal

Applications

• Suitable for heavy stock removal on aluminium fabrications
• Ideal for surface preparation on painted panels prior to repainting
• Can be used for blending and finishing in woodworking tasks
• Used with orbital sanders fitted to dust-extraction systems
• Suitable for sanding composite panels in automotive refurbishment

What backing does it use and why does that matter?

It uses a J-weight cloth backing that balances flexibility with abrasion resilience to endure repeated contact and conform to curved components.

How does dust control work with this product?

The proprietary multi-hole pattern combined with anti-static treatment helps channel dust into a vacuum system while reducing electrostatic attraction of particles.

Which materials will it cut effectively?

The precision-shaped mineral is formulated to remove stock efficiently from aluminium, steel, hardwoods, softwoods and typical composite laminates.

How does the abrasive maintain cutting performance over time?

As the mineral fractures it forms new Sharp edges, resulting in even wear and prolonged useful life compared with conventional abrasives.

What attachment options are compatible with the disc?

The disc is offered with adhesive-backed/PSA mounting and can be specified for Hookit™-style systems to enable fast replacement.
