3M 7100025486 Psa Disc 24 in 60 Grit Aluminum Oxide

Product Description

The 3M 7100025486 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal in industrial and trade finishing applications. This 24-inch disc uses aluminum oxide abrasive grain at 60 grit, placing it in the medium grade range — well suited for rapid stock removal, surface leveling, and prep work before finer finishing passes. The X-weight cloth backing provides the rigidity and tear resistance needed for demanding grinding and sanding tasks. The flexible construction allows the disc to conform slightly to workpiece contours without sacrificing cutting efficiency.

This disc is intended for use on bench top motors and random orbital sanders capable of accepting a 24-inch PSA-mount disc. It is commonly used in metal fabrication shops, woodworking operations, and industrial maintenance environments where large-format material removal is required. The PSA mounting system allows for fast disc changes without hardware, reducing downtime between passes. No vacuum holes are included, making this disc appropriate for dry sanding setups without dust extraction port requirements.

Key Features

• 24-inch disc diameter for large-format surface coverage
• 60 grit aluminum oxide abrasive for medium-grade, high-rate stock removal
• X-weight cloth backing for durability and resistance to tearing under load
• Pressure-sensitive adhesive mount for tool-free installation and removal
• Flexible construction allows moderate contouring to workpiece surfaces
• Compatible with bench top motors and random orbital sanders

Compatibility

Designed for use with bench top motors and random orbital sanders that accept 24-inch PSA-mount abrasive discs. No vacuum holes are present; verify that the backing pad does not require a hole pattern before installation.

Installation Notes

Installation is performed by trade professionals or skilled operators familiar with large-format grinding and sanding equipment. Power down and lock out the machine before mounting or removing the disc. Align the PSA disc carefully to the backing pad before pressing firmly to ensure full adhesive contact and prevent disc slippage during operation. Inspect the disc for tears, voids, or edge lifting before each use and replace if any defects are found.
