3M 7010326519 Psa Abrasive Disc 120 Grit 8 Inches

Product Description

The 3M 7010326519 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface finishing and material removal on bench top motors and random orbital sanders. Built on an X-weight cloth backing, it delivers the rigidity and flexibility needed for aggressive stock removal while conforming to contoured surfaces. The aluminum oxide abrasive grain is rated Fine grade at 120 grit, making it well suited for intermediate finishing passes on metal, wood, and composite materials. The maroon disc measures 8 inches in diameter and mounts directly to PSA-compatible backup pads without mechanical fasteners.

This disc is intended for professional finishing environments including fabrication shops, metal working operations, and woodworking facilities. It is compatible with bench top motors and random orbital sanders that accept 8-inch PSA-mount discs. The flexible cloth backing allows the disc to track curved surfaces without tearing under load. No vacuum holes are present, so it is best suited for setups that do not rely on through-disc dust extraction.

Key Features

• Aluminum oxide abrasive grain for consistent cut rate on metal and wood
• 120 grit Fine grade for intermediate finishing and scratch refinement
• X-weight cloth backing provides durability and surface flexibility
• PSA mount — adheres directly to compatible backup pads, no hardware required
• 8-inch diameter fits bench top motors and random orbital sanders
• No vacuum holes — optimized for non-dust-extraction setups

Compatibility

Designed for use with bench top motors and random orbital sanders that accept 8-inch PSA-mount abrasive discs.

Installation Notes

Mounting is performed by pressing the PSA-coated back of the disc firmly onto a clean, dry backup pad of matching diameter. Ensure the backup pad surface is free of debris or adhesive residue before application to achieve full contact and prevent disc separation during use. Inspect the disc for tears or edge lifting before each use and replace if damaged. Operators should follow applicable shop safety guidelines including eye protection and dust control measures appropriate to the material being worked.
