3M Adhesive-Backed/PSA Sanding Disc, 152.4mm Disc Diameter, 1000 Grit size - 7100335389

This adhesive-backed/PSA sanding disc is a precision abrasive disc designed for finishing operations in industrial settings. It combines precision-shaped grain mineral on a C-paper backing with an adhesive Hookit-style attachment to deliver controlled material removal for surface refinement in automation, electronics, electrical and mechanical workflows.

Features & Benefits

• Precision-shaped grain cuts up to twice as fast
• Anti-load coating reduces clogging for longer use
• Multi-hole pattern improves dust extraction efficiency
• Hookit adhesive allows quick on/off disc changes
• Paper backing balances flexibility with dimensional stability

Applications

• Suitable for scuffing and prep for topcoat on metal substrates
• Ideal for coating refinement and rework in production lines
• Used for de-flashing and edge rounding in component manufacture
• Can be used for fine finishing on painted assemblies
• Suitable for light smoothing of composites and gelcoat surfaces

How does the disc manage dust during powered sanding?

The disc is available with a proprietary multi-hole Xtract pattern that channels particles to extraction systems, reducing airborne dust and workpiece loading.

Which attachment method is used for Rapid changes?

It uses a PSA Hookit-style adhesive Interface that permits quick replacement on compatible multi-hole back-up pads.

What backing material supports repeated hand and machine use?

A C-weight paper backing provides a compromise between flexibility for contours and durability for multiple passes.

Are there fine-grade options suitable for automotive finishing?

Yes, the product range includes fine grades up to 1000+ grit for fine finishing and coating refinement.

How does the abrasive composition affect cutting behaviour?

The precision-shaped grain forms Sharp peaks that Slice material, producing cooler cutting, consistent finishes and extended life.
