3M Adhesive-Backed/PSA Sanding Disc, 76.2mm Disc Diameter, 220 Grit size - 7100282510

This adhesive-backed/PSA sanding disc is a precision-shaped grain abrasive designed for demanding material removal and finishing tasks. It pairs an abrasive mineral that fractures to maintain cutting edges with a robust cotton cloth backing, delivering consistent sanding performance across metals, woods and composites when used with a vacuum-enabled random orbital Sander and compatible multi-hole back-up pad.

Features & Benefits

• Precision-shaped grain delivers sustained cutting and longer life
• Open coat abrasive reduces loading when sanding tacky surfaces
• Anti-static treatment helps control electrically charged swarf
• Cotton cloth backing offers wear resistance and flexibility
• Hookit-compatible adhesive enables quick disc changes and uptime

Applications

• Suitable for heavy stock removal on aluminium and steel
• Ideal for blending and finishing hardwoods and softwoods
• Used for surface preparation on composite panels and gelcoat
• Can be used with vacuum sanders in automotive refinishing
• Suitable for bulk sanding in electronics enclosure manufacture

How does the abrasive maintain sharpness during use?

The grain is engineered to fracture as it wears, producing fresh cutting points that sustain material removal rates and even wear.

What role does the anti-static treatment play in workshop settings?

It neutralises static charge from sanding, which reduces swarf cling to equipment and workpieces and supports more effective dust extraction with a vacuum system.

Which attachment method does it use for Rapid replacement?

The disc uses a Hookit-style adhesive-backed system so operatives can change discs quickly without adhesive residue transfer.

What backing behaviour should users expect under load?

The cotton cloth backing balances flexibility and wear resistance, maintaining contact on contoured surfaces while resisting premature tearing.

Can finer abrasives from the same design be used for finishing tasks?

Yes, finer grades of this abrasive construction are suitable for blending and finishing applications on metals and woods.
