3M Adhesive-Backed/PSA Sanding Disc, 150mm Disc Diameter, Precision Shaped Grain Abrasive - 7100284342

This adhesive-backed/PSA sanding disc is a high-performance abrasive designed for heavy stock removal and finishing in industrial sanding operations. It combines precision-shaped mineral technology with a cloth backing to deliver fast cutting on metals, wood and composite substrates while supporting dust management when used with extraction systems.

Features & Benefits

• Precision‑Shaped Grain delivers Rapid material removal and extended life
• Open coat construction reduces loading for continued cutting performance
• Anti‑static treatment minimises charged swarf adhesion during sanding
• J‑weight cloth backing balances flexibility with wear resistance
• Hookit attachment enables quick disc changes to reduce downtime

Applications

• Suitable for aggressive metal grinding and deburring in fabrication
• Used for surface preparation of aluminium prior to finishing
• Ideal for Rapid stock removal on hardwood and softwood components
• Can be used for sanding composites, gelcoat and fibreglass panels
• used with random orbital sanders and vacuum back‑up pads for extraction

How does the abrasive maintain cutting efficiency as it wears?

The mineral fractures to expose new Sharp edges continuously, preserving cut rate and consistency throughout life.

What backing characteristics support repeated use on powered tools?

The cloth substrate offers toughness and flexibility, resisting wear while conforming to contoured workpieces during orbital motion.

Which dust‑management measure improves workplace cleanliness?

Pairing the disc with a multi‑hole back‑up pad and an effective vacuum harnesses the design for superior extraction and reduced loading.

Which materials are appropriate for heavier grades?

Coarser grits are suited to heavy stock removal on ferrous metals and composites where Rapid material take‑off is required.
