3M Precision Shaped Ceramic Grain Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 127 mm, 150+ Grade, 150 Grit

This adhesive-backed/PSA sanding disc is a net-backed abrasive designed for general sanding, stock removal and surface preparation across multiple substrates. It combines a blend of aluminium oxide and precision-shaped ceramic grain to deliver consistent cutting and finishing performance when used with a compatible backing pad and extraction system. The hook-and-loop attachment Interface allows quick disc changes and the net construction facilitates dust removal when paired with a vacuum-equipped tool.

• Precision-shaped ceramic grain improves cut rate and longevity
• PSA attachment enables fast, secure pad changes
• Net backing permits effective dust extraction when vacuumed
• Pattern coating reduces loading and aids finish quality
• Resin bond ensures consistent abrasive distribution during use

• Suitable for scuffing and intermediate sanding of painted surfaces
• Ideal for prepping metal panels prior to welding or coating
• Used for abrading composite and gelcoat surfaces in fabrication
• Can be used for removing sealers, fillers and putties during repair
• Suitable for integration into automated sanding stations with extraction

A mixed mineral formulation pairs aluminium oxide with 3M’s precision-shaped ceramic grain to maintain cutting efficiency while extending abrasive life.

Keep them in their original packaging at 16°C to 26°C and 35 to 50% relative humidity on a first-in, first-out basis to minimise shelf degradation.

The product family is designed for random orbital tools

The open backing enables dust to pass through to a backing pad and vacuum system, reducing airborne particulates when extraction is used.

The integrated loop Interface is compatible with Hookit-style hook-and-loop backing pads for Rapid automated or manual disc replacement.
