3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 125 mm, 600 Grade, 50 Grit

This adhesive-backed/PSA sanding disc is a precision abrasive for industrial surface preparation and finishing. Designed with precision-shaped grain on a C-weight paper backing, it delivers controlled material removal and a consistent finish for metal, painted surfaces, composites and wood when used with appropriate extraction systems.

• Precision-shaped grain increases cut rate and lowers rework
• Anti-load coating extends life and reduces clogging
• Adhesive-backed PSA attachment enables quick on/off changes
• Multi-hole pattern improves dust extraction efficiency
• C-weight paper backing balances flexibility and durability

• Suitable for dimensioning and coating material removal on metal
• Ideal for scuffing and prep before topcoat application
• Can be used for de-flashing and edge rounding in mechanical parts
• Used for coating refinement and rework in electrical assemblies
• Suitable for fine finishing tasks in electronics fabrication

The multi-hole Xtract pattern works with extraction systems to remove up to 99% of generated dust, reducing loading and exposure in the workspace.

The precision-shaped grain and anti-load coating maintain cutting performance across metals, paint coatings, composites, gelcoat and wood before dressing or disc change is required.

The PSA backing permits fast disc swaps and aligns with multi-hole back-up pads to minimise downtime and maintain consistent abrasive contact during hand or power tool sanding.

Fine grades extend up to 1000 grit, providing incremental options for refined surface finishes beyond coarse preparation.
