3M 7010326531 Psa Cloth Disc 18 Inch 50 Grit Ao

Product Description

The 3M 7010326531 is a PSA cloth sanding disc designed for heavy-duty material removal in industrial and trade finishing applications. The disc uses an aluminum oxide abrasive grain bonded with a resin system that resists heat buildup, extending working life during aggressive stock removal. A pressure-sensitive adhesive backing mounts directly to a backup pad or steel platen without mechanical fasteners, allowing fast disc swaps with clean removal. The X-weight cloth backing resists tearing and edge fraying under sustained load. At 18 inches in diameter and 50 grit, this disc is suited for wide-surface grinding and blending tasks where aggressive cut rates are required.

This disc is used in industrial grinding and finishing operations on metal, wood, and composite surfaces. At 50 grit and 18 inches, it is appropriate for initial stock removal and surface leveling on large flat workpieces. The disc supports both wet and dry sanding conditions, making it adaptable to shop environments where coolant or water is used to control heat or dust. Trade fabricators, millwrights, and finishing technicians working with stationary disc sanders or large platen machines are the primary installers and users of this disc.

Key Features

• Pressure-sensitive adhesive backing adheres securely to backup pads and steel platens with clean, fast removal for quick replacement
• X-weight cloth backing withstands aggressive applications without tearing or edge wear
• Aluminum oxide abrasive delivers fast cut rates and long service life across a wide range of surfaces
• Resin bond system dissipates heat to protect the disc and extend abrasive life
• Compatible with both wet and dry sanding applications

Compatibility

Designed for use with backup pads and steel platens that accept 18-inch PSA-mount sanding discs in stationary or large-format disc sanding equipment.

Installation Notes

Installation is performed by trade fabricators or finishing technicians operating disc sanders or platen grinders. Before mounting, ensure the machine is fully powered down and the platen or backup pad surface is clean and free of adhesive residue from prior discs. Press the PSA disc firmly and evenly from center to edge to achieve full adhesive contact and prevent edge lifting during operation. Inspect the disc for tears or delamination before each use and replace if any damage is present.
