3M Precision Shaped Ceramic Grain Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 76.2 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 precision-shaped ceramic mineral blend with an open mesh backing to enable dust extraction when used with a compatible backing pad and vacuum system, and it attaches quickly via a hook-and-loop style Interface for Rapid disc changes on orbital sanders.

• Precision shaped ceramic grain delivers Faster cut rates and longevity
• Net backing permits effective dust extraction with vacuum systems
• Hook-and-loop attachment allows Rapid tool-side disc replacement
• Patterned coating reduces loading and improves finishing consistency
• Blend of aluminium oxide and ceramic supports diverse substrate work

• Suitable for scuffing and intermediate sanding of primer and paintwork
• Ideal for stock removal on composites and gelcoat
• Used for surface preparation of fillers, sealants and putties
• Can be used for finish sanding on whitewood and lacquers
• Suitable for metal deburring and smoothing in mechanical assembly

The net backing facilitates extraction through the disc when paired with a supporting tool and vacuum system, reducing dust in the work area and improving visibility.

A blend of aluminium oxide and 3M proprietary precision-shaped ceramic grain is employed to balance Durable cutting performance with consistent finish quality across varying materials.

The loops integrated into the net backing are designed to mate with a Hookit-style hook-and-loop pad for quick, non-aligned disc changes.

Store in original packaging at 16°C to 26°C and 35 to 50% relative humidity on a first-in to first-out basis to maintain shelf life and abrasive behaviour.

Its pattern-coated resin on a net substrate supports reduced loading and stable finishing for automotive refinishing, electronics panel preparation and mechanical surface finishing.
