3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Cutting Disc, 125 mm, 320+ Grade, 50 Grit

This adhesive-backed/PSA sanding disc is a cloth-backed abrasive designed for heavy stock removal and finishing tasks in industrial settings. It uses precision-shaped grain to maintain cutting performance as the mineral fractures and renews cutting edges. The product is suitable for applications where efficient dust management and Durable abrasive life are required when working on metal, wood and composite substrates.

• Precision-shaped grain cuts quickly and prolongs abrasive life
• Anti-static treatment reduces electrostatic swarf adhesion during sanding
• Open-coat construction prevents loading and sustains cutting performance
• Cloth backing combines wear resistance with flexibility for contoured work
• Hookit attachment enables Rapid disc changes and optimised usage

• Suitable for removing weld spatter and preparing metal surfaces for coating
• Ideal for blending and finishing aluminium panels and components
• Used for shaping and finishing hardwood and softwood parts
• Can be used for sanding fibreglass and gelcoat in composite repairs
• Suitable for use with vacuum-equipped random orbital sanders

The precision-shaped grain fractures predictably as it wears, producing fresh cutting edges that preserve cut rate and extend service life.

Yes, the open-coat abrasive formulation and cloth backing provide effective stock removal on a range of materials from softwoods to hard metals.

By neutralising static charge, the treatment helps prevent swarf clinging to surfaces, improving efficiency when used with an effective extraction system.

It is supplied with a Hookit-style PSA backing for adhesive attachment to compatible back-up pads, facilitating quick replacements.

It is intended for automation, electronics, electrical and mechanical workshop processes requiring consistent abrasive performance and reduced downtime.
