3M Adhesive-Backed/PSA Sanding Disc, 76.2mm Disc Diameter, 40 Grit size - 7100284886

This adhesive-backed/PSA sanding disc is a self-adhesive abrasive designed for heavy stock removal and finishing in industrial workshops. It combines precision-shaped grain abrasive technology with a Durable cotton cloth backing to deliver Rapid cutting on metals, composites and woods while enabling improved dust control when used with vacuum extraction systems.

Features & Benefits

• Precision-shaped grain provides Faster cut rates and longer life
• Anti-static treatment reduces charged swarf and dust cling
• Open coat construction prevents loading for consistent performance
• Hookit-compatible backing allows quick disc changes and uptime
• Cloth backing offers high durability and Flex for contoured surfaces

Applications

• Suitable for heavy stock removal on steel and aluminium panels
• Ideal for surface preparation prior to bonding or painting
• Used for blending and finishing on hardwoods and composites
• Can be used with random orbital sanders fitted to dust extractors
• Suitable for angle grinder use in metalworking with PSA attachment

How does the disc manage dust during operations?

The disc incorporates an anti-static treatment that neutralises electrostatic charge on swarf, aiding an effective vacuum system to remove dust and reduce loading.

What backing material supports repeated use on shaped parts?

A cotton cloth backing gives wear resistance with flexibility, allowing the abrasive to conform to contours while withstanding mechanical stress.

Which grain behaviour delivers its cutting performance?

The precision-shaped grain fractures as it wears, creating fresh Sharp edges that maintain cutting efficiency and extend usable life.

What attachment options suit quick replacements?

The PSA adhesive-backed format is compatible with hookit-style backup pads for Rapid removal and fitting to minimise downtime.

Can it be used across different substrates in production lines?

Yes, the abrasive is effective on metals, fibreglass, gelcoat, hardwoods and softwoods for a range of industrial finishing tasks.
