3M Adhesive-Backed/PSA Sanding Disc, 152.4mm Disc Diameter, 120 Grit size - 7100288136

This adhesive-backed/PSA sanding disc is a net-backed abrasive designed for general and intermediate sanding, stock removal and surface preparation across a range of substrates. It is engineered for use with a Hookit-compatible hook-and-loop attachment system and designed to extract dust when paired with a suitable support pad and vacuum system, making it appropriate for workshop and industrial power sanding environments.

Features & Benefits

• Precision-shaped ceramic grain improves cut rate and life
• Net backing enables effective dust extraction with vacuum
• Pattern-coated resin reduces loading and aids finish
• Hook-and-loop compatibility allows Rapid disc replacement
• Blend of aluminium oxide and ceramic supports mixed substrates

Applications

• Suitable for scuffing and paint preparation on automotive panels
• Ideal for sanding composites and gelcoat in fabrication
• Used for finishing and blending filler and putty surfaces
• Can be used for metal finishing prior to coating or inspection
• Suitable for general stock removal on wood and whitewood

What abrasive composition is used for enhanced cutting performance?

It combines aluminium oxide with a proprietary precision-shaped ceramic grain to balance fast material removal with controlled finish.

How should discs be stored to preserve performance?

Keep in original packaging at 16°C to 26°C and 35 to 50% relative humidity on a first-in, first-out basis to avoid reduced shelf life.

Which attachment methods work with this product for Rapid changes?

Loops integrated into the net backing pair with a Hookit hook-and-loop system for fast replacement without hole alignment.

What operating speeds are applicable for different diameters?

Maximum orbits per minute vary by size

smaller diameters allow higher OPM while larger diameters have lower OPM limits as specified by tool compatibility.
