3M Adhesive-Backed/PSA Sanding Disc, 152.4mm Disc Diameter, 400 Grit size - 7100335388

This adhesive-backed/PSA sanding disc is a high-performance abrasives solution designed for industrial surface preparation and finishing across automation, electronics, electrical and mechanical sectors. It combines precision-shaped grain mineral on a C-weight paper backing to deliver consistent material removal and finish control during both hand and power tool sanding operations.

Features & Benefits

• Precision-shaped grain cuts Faster and reduces downtime
• Anti-load coating prolongs abrasive life and consistency
• Hookit/PSA attachment enables Rapid disc changes
• Multi-hole Xtract pattern supports superior dust extraction
• C-paper backing balances flexibility with durability

Applications

• Suitable for metal deburring and dimensioning tasks in workshops
• Ideal for scuffing and prep prior to topcoat application
• Used for coating material removal and coating refinement
• Can be used for de-flashing and edge rounding operations
• Suitable for sanding composites, gelcoat and various woods

What backing material does it use and why does that matter?

It uses C-weight paper which provides a compromise between flexibility and robustness, allowing multiple job types with consistent contact and controlled conformability.

How does dust extraction improve operator conditions?

The proprietary multi-hole Xtract layout reduces airborne dust by enabling up to 99% extraction when used with compatible extraction systems, improving workshop cleanliness and exposure control.

Which abrasive technology delivers the cutting performance?

Precision-shaped grain formed by microreplication creates Sharp cutting peaks that Slice material, offering Faster cut rates compared with conventional aluminium oxide.

What sizes and grades are available for varied tasks?

The product range spans fine to coarse grades, extending from around 80+ through to 1000+ to suit tasks from aggressive material removal to fine finishing.

How does the attachment type affect workflow?

The PSA/Hookit Interface permits quick on/off changes and alignment with multi-hole back-up pads, reducing time spent replacing discs and limiting downtime.
