3M 7100035587 Psa Cloth Disc 9 Inch 80 Grit Aluminum Oxide

Product Description

The 3M 7100035587 is a PSA cloth sanding disc designed for heavy-duty material removal in professional finishing and fabrication environments. The pressure-sensitive adhesive backing bonds securely to a backup pad or steel platen and releases cleanly for fast disc changes. The disc uses aluminum oxide abrasive, which cuts aggressively and maintains a long service life across a wide range of surfaces. An X-weight cloth backing provides the structural rigidity needed for demanding applications without tearing or edge wear. A resin bond layer protects the abrasive from heat buildup, extending disc life under sustained use.

This disc is suited for metalworking, woodworking, and composite surface preparation in both shop and field environments. It performs in wet or dry operating conditions, making it adaptable to a range of finishing workflows. The 9-inch diameter and 80-grit cut make it a practical choice for intermediate stock removal and surface leveling before final finishing steps. Fabricators, welders, millwrights, and industrial maintenance technicians are the primary users of this disc format.

Key Features

• Pressure-sensitive adhesive backing adheres firmly to backup pads and steel platens, then releases cleanly for quick replacement
• X-weight cloth backing resists tearing and edge wear during aggressive material removal
• Aluminum oxide abrasive delivers fast cutting action and extended service life on metal, wood, and composites
• Resin bond construction reduces heat damage to the abrasive layer, prolonging disc performance
• Compatible with both wet and dry sanding applications

Compatibility

Designed for use with standard PSA backup pads and steel platens that accept 9-inch pressure-sensitive adhesive sanding discs.

Installation Notes

Mounting and disc changes should be performed with the sanding machine powered off and fully stopped. Ensure the backup pad or platen surface is clean and free of debris before applying the disc to achieve full adhesive contact. Inspect the disc for damage before each use and replace immediately if tearing, delamination, or abrasive loss is observed. Follow applicable shop safety guidelines, including use of eye protection and dust collection equipment when sanding.
