3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 125 mm, 1000+ Grade, 50 Grit

This adhesive-backed/PSA sanding disc is a high-grit finishing abrasive designed for industrial sanding tasks. Intended for use with hook-and-loop and PSA backing systems, it employs precision-shaped grain on a C-paper backing to deliver controlled material removal and consistent surface finish in manufacturing and maintenance environments.

• Precision-shaped grain cuts up to 2x Faster for reduced cycle time
• Anti-load coating reduces clogging for extended cutting life
• Multi-hole Xtract pattern enables up to 99% dust extraction
• C-weight paper backing balances flexibility with job durability
• Hookit/PSA attachment allows quick on/off disc replacement

• Suitable for fine prep and scuffing before topcoat on painted surfaces
• Ideal for coating removal and refinement on metal components
• Used for de-flashing and edge rounding in mechanical assembly
• Can be used for finish sanding on composites and gelcoat
• Suitable for fine abrasive work in electronics enclosure fabrication

The disc is offered in a 1000 grit grade within the 1000+ fine range for high-grit precision sanding.

The precision-shaped grain slices through metal coatings and substrates, producing fewer rogue scratches and reducing rework.

A C-paper backing provides a balance of flexibility and durability suitable for hand and power tool sanding.

The proprietary multi-hole Xtract layout supports superior dust extraction, improving workshop cleanliness and the operator environment.

It is used across automation, electrical, electronics and mechanical sectors for fine finishing and paint preparation.
