3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Cutting Disc, 125 mm, 120 Grade, 50 Grit

This adhesive-backed/PSA sanding disc is a 125mm abrasive designed for demanding material-removal and finishing tasks in industrial settings. It combines a Durable J-weight cloth backing with precision-shaped grain to deliver consistent cutting on metals, composites and timber when used with random orbital sanders and appropriate dust extraction.

• Precision-shaped grain provides Rapid material removal and extended life
• Cloth backing resists wear while maintaining flexibility for contoured surfaces
• Anti-static treatment reduces swarf cling and improves dust management
• Open-coat construction limits loading to sustain cutting performance
• Hookit attachment allows quick disc changes and reduced downtime

• Suitable for heavy stock removal on aluminium components
• Ideal for surface blending and finishing in automotive refinishing
• Used for sanding composite panels in aerospace and electronics enclosures
• Can be used for metalworking preparation prior to coating or welding
• Suitable for woodworking tasks on hardwoods and softwoods requiring Rapid cut

The disc includes an anti-static treatment and is compatible with multi‑hole extraction systems to reduce dust accumulation on the abrasive and workpiece when connected to a vacuum back‑up pad.

The J-weight cloth backing offers a balance of wear resistance and pliability, enabling reliable contact on irregular surfaces without premature failure.

The precision-shaped grain fractures to form Sharp cutting points, optimising performance on metals, gelcoat, aluminium and composite substrates for a sustained cut rate.

The hook-style PSA attachment permits fast, secure disc swaps, lowering changeover time and increasing parts throughput in production environments.
