3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 127 mm, 320+ Grade, 50 Grit

This adhesive-backed/PSA sanding disc is designed for industrial surface preparation and finishing in mechanical, electrical and automation environments. It combines precision-shaped abrasive mineral on a C-weight paper backing with a pressure-sensitive adhesive attachment to facilitate Rapid disc changes. The product suits process-driven workflows where consistent cut rate and dust control are required.

• Precision-shaped grain delivers up to 2x cutting rate and cooler sanding
• PSA attachment enables quick on/off changes and reduced downtime
• Anti-load coating reduces clogging for longer continuous use
• Multi-hole Xtract pattern improves dust removal up to 99%
• C-paper backing balances flexibility with dimensional stability

• Suitable for de-flashing and dimensioning of metal components
• Ideal for scuffing paint and prep prior to topcoat application
• Used for coating material removal and surface refinement
• Can be used for edge rounding and composite surface finishing
• Suitable for operations requiring dust extraction in workshops

The PSA system provides a flat, secure bond to compatible hook-and-loop style or backing pads, enabling handheld and powered sanding tools to operate without additional fastening hardware.

The multi-hole configuration channels particulates into extraction systems, lowering airborne dust and reducing abrasive loading during prolonged periods of sanding.

The precision-shaped mineral slices through metals, gelcoat, coatings and wood, maintaining cutting action while producing a consistent finish suited to follow-on processes.

The C-weight paper backing combines sufficient stiffness for controlled material removal with adequate flexibility for contour sanding, allowing multiple job types with a single disc.
