3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 152.4 mm, 800 Grade, 800 Grit

This adhesive-backed/PSA sanding disc is a 152.4 mm, fine-grit abrasive designed for precision surface finishing in industrial settings. It employs precision-shaped grain on a C-weight paper backing to deliver consistent cutting behaviour and is suitable for hand or power tool use where controlled material removal and finish quality are required.

• Precision-shaped grain increases cut rate and longevity
• Anti-load coating reduces clogging for extended use
• PSA backing enables quick, accurate disc changes
• C-weight paper backing balances flexibility and durability
• Multi-hole Xtract pattern improves dust extraction efficiency

• Suitable for metal dimensioning and edge rounding tasks
• Ideal for scuffing and preparation prior to topcoat application
• Used for coating refinement and rework in workshops
• Can be used for de-flashing and coating material removal
• Suitable for mixed-material jobs including composites and wood

The multi-hole extraction layout is designed to work with compatible extraction systems to remove a high proportion of sanding debris and help prevent loading.

The PSA backing is compatible with Hookit™ style back-up pads, enabling quick stick-and-remove changes for both hand and power tool workflows.

The precision-shaped mineral is formulated to cut through metals, painted surfaces, composites, gelcoat and various woods while maintaining a consistent finish.

The C-weight paper backing provides a balance of flexibility and strength so a single disc can be used across multiple jobs and tool types without Rapid wear.
