3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 76.2 mm, 120 Grade, 220 Grit

This adhesive-backed/PSA sanding disc is a fast-cutting abrasive engineered for heavy stock removal and finishing across woods, metals and composites. It combines precision-shaped grain mineral with a Durable cotton cloth backing and an adhesive hook-and-loop compatible attachment to support efficient sanding workflows when paired with a vacuum-equipped random orbital sander.

• Precision-shaped grain delivers continuous sharpness for extended life
• Open coat construction reduces loading for sustained cutting
• Anti-static treatment neutralises charge to manage dust
• Cotton cloth backing resists wear while remaining flexible
• Optimised for dust extraction to improve productivity

• Suitable for heavy stock removal on aluminium panels
• Ideal for paint preparation on metalwork and bodyshops
• Used for blending and finishing hardwoods and softwoods
• Can be used for composite surface preparation in manufacturing
• Suitable for use with vacuum-backed random orbital sanders

It is built on a cloth backing designed for wear resistance and flexibility and uses an adhesive-backed/PSA Interface compatible with hook‑it‑style backup pads for Rapid disc changes.

The product features an anti-static treatment and a multi-hole extraction pattern intended to work with an effective dust collection system to prevent loading and reduce airborne swarf.

The shaped mineral grain targets aluminium, metals, fibreglass, gelcoat, hardwoods, softwoods and composite substrates where fast cutting and extended disc life are required.

As the grain wears it fractures to create new cutting edges, maintaining cutting performance and consistent removal rates over prolonged use.
