3M Adhesive-Backed/PSA Sanding Disc, 125mm Disc Diameter, 220+ Grade - 7100281811

This adhesive-backed/PSA sanding disc is a self-adhesive abrasive intended for industrial material removal and finishing tasks. It employs precision-shaped mineral for sustained cutting performance and is built on a flexible J-weight cloth backing to withstand demanding sanding operations across varied substrates in production and maintenance environments.

Features & Benefits

• Precision-shaped grain delivers continuous fracturing and sustained cutting
• Open coat construction reduces loading for longer working life
• Anti-static treatment minimises charge and improves dust handling
• Hookit attachment enables Rapid disc changes and reduced downtime
• Cloth backing balances wear-resistance with conformability for contours

Applications

• Suitable for heavy stock removal on metal components
• Ideal for blending and finishing aluminium panels
• Can be used for sanding hardwoods and softwoods in assemblies
• Used for preparing composite surfaces such as fibreglass and gelcoat
• Suitable for integration with vacuum-equipped random orbital sanders

What surface charge behaviour should I expect during sanding?

The abrasive carries an anti-static treatment that neutralises electrostatic build-up, reducing adherence of swarf to the disc and workpiece when used with extraction.

Which backing type supports flexible contact on irregular parts?

The product uses a J-weight cloth backing that combines flexibility with wear resistance to maintain contact on contoured surfaces.

How does the abrasive maintain cutting performance as it wears?

The precision-shaped grains are engineered to fracture into Sharp edges, preserving cutting action and even wear throughout service life.

What attachment method is used for quick changes?

A hook-and-loop style Hookit system provides secure mounting and fast replacement of discs on compatible back-up pads.

Which substrate categories are appropriate for this disc?

It is formulated for wood, metals and composite materials in applications requiring both aggressive stock removal and finer blending tasks.
