3M Ceramic Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 125 mm, 240+ Grade, 50 Grit

This adhesive-backed/PSA sanding disc is a net-backed abrasive intended for general sanding, scuffing and surface preparation across multiple substrates in industrial settings. Designed for use with a Hookit™ hook-and-loop support pad and compatible extraction systems, it facilitates dust removal and Rapid disc changes for workflow efficiency in automation, electronics, electrical and mechanical environments.

• Precision-shaped ceramic grain for Faster material removal
• Net backing enables effective dust extraction when vacuumed
• Hookit™ loop integration allows swift, tool-free disc swaps
• Proprietary patterned coating reduces loading and improves finish
• Blend of aluminium oxide and ceramic ensures balanced cut and life

• Suitable for scuffing primer and paint prior to overcoating
• Ideal for preparing gelcoat and composite surfaces
• Used for intermediate sanding of fillers and putties
• Can be used for metal finishing in fabrication tasks
• Suitable for surface preparation on whitewood components

It combines aluminium oxide with a proprietary precision-shaped ceramic grain to deliver controlled cut rates and wear 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 premature degradation.

Maximum orbits per minute vary by disc diameter with higher allowable OPM for medium sizes and lower for the largest sizes to match tool specifications.

Loops are incorporated into the net backing so holes need not be aligned with the backing pad, simplifying fitment and repeatability.
