3M Adhesive-Backed/PSA Sanding Disc, 127mm Disc Diameter, 800 Grit size - 7100334764

This adhesive-backed/PSA sanding disc is a 127mm abrasive disc engineered for fine finishing in industrial settings. It uses precision-shaped grain on a C-paper backing to deliver consistent cutting performance for metal, coatings and composite surfaces while fitting Hookit-style back-up pads and supporting dust extraction workflows.

Features & Benefits

• Precision-shaped grain cuts up to 2x faster, enhancing throughput
• Anti-load coating reduces clogging for longer usable life
• Multi-hole Xtract pattern enables up to 99% dust extraction
• C-weight paper backing balances flexibility with durability
• PSA attachment allows quick on/off disc changes during shifts

Applications

• Suitable for scuffing and prep for topcoat on painted panels
• Used for coating refinement and rework on production lines
• Ideal for de-flashing and edge rounding on fabricated parts
• Can be used for dimensioning and material removal on metal
• Suitable for finishing composite and gelcoat components

What grit range is available for fine finishing tasks?

Fine grades extend up to 1000 grit with multiple intermediate steps, including an 800 grit option designed for careful surface refinement.

How does the disc support extractive sanding systems?

The proprietary multi-hole layout pairs with Xtract systems to markedly reduce airborne dust and improve workshop cleanliness during powered sanding.

Which surfaces will the adhesive system work on effectively?

The PSA bond adheres reliably to Hookit-style pads and performs well when sanding metals, painted coatings, composites, gelcoat and various woods.

What backing and bond type contribute to handling performance?

A C-paper backing provides a balance of flexibility and toughness while the adhesive-backed attachment enables fast disc replacements on the pad.
