3M Adhesive-Backed/PSA Sanding Disc, 203.2mm Disc Diameter, 320 Grit size - 7100284267

This adhesive-backed/PSA sanding disc is a cloth-backed abrasive designed for heavy stock removal and finishing in industrial settings. It uses Precision Shaped Grain to maintain cutting performance as the abrasive wears and is intended for use with a dust-extraction system to reduce airborne particles during sanding operations.

Features & Benefits

• Precision Shaped Grain provides continuous self-sharpening cut
• Open coat design prevents loading and extends usable life
• Anti-static treatment reduces static and helps manage swarf
• Cotton cloth backing combines durability with flexibility
• Compatible with PSA attachment for quick disc changes

Applications

• Suitable for Rapid material removal from aluminium panels
• Ideal for surface blending on hardwood and softwood
• Used for preparing composite and fibreglass surfaces
• Can be used for metal finishing prior to further processing
• Suitable for production sanding with vacuum-equipped sanders

What backing material is used and how does it affect durability?

The backing is cotton cloth which offers wear resistance while retaining flexibility for contoured surfaces and extended disc life.

How does the abrasive maintain cutting performance over time?

The grain fractures to form fresh cutting edges as it wears, preserving cutting speed and consistency during prolonged use.

Is the disc suitable for use with dust extraction equipment?

Yes, the product is designed to work with extraction systems, and its anti-static treatment improves dust and swarf control when vacuumed.

Which materials can it effectively abrade?

It performs on metals, aluminium, hardwoods, softwoods, gelcoat and composites for both heavy stock removal and finer finishing tasks.
