3M 7000118919 Psa Cloth Disc 348D 2 Inch 36 Grit Ao

Product Description

The 3M 7000118919 is a PSA cloth sanding disc in the 348D series, designed for heavy-duty material removal on metal, wood, and composite surfaces. The disc uses a pressure-sensitive adhesive backing that bonds securely to a backup pad or steel platen and releases cleanly for fast swaps. The aluminum oxide abrasive grain delivers aggressive stock removal and maintains cutting performance across extended use. A resin bond system protects the grain layer from heat buildup, extending disc life in high-cycle production environments. At 2 inches in diameter and 36 grit, this disc is suited for aggressive grinding and surface conditioning tasks performed by metalworkers, fabricators, and finishing technicians.

The 348D disc is intended for use in both wet and dry sanding applications, making it adaptable to a range of shop conditions. The X-weight cloth backing resists tearing and edge wear under lateral and downward pressure, which is critical when working on tight radii or contoured parts. Typical applications include weld blending, rust removal, edge deburring, and surface prep ahead of coating or plating. This disc is built for production environments where speed of change and consistent cut rate directly affect throughput.

Key Features

• Pressure-sensitive adhesive backing adheres firmly to backup pads or steel platens and removes cleanly for quick disc changes
• X-weight cloth backing resists tearing and edge wear during aggressive sanding passes
• Aluminum oxide abrasive provides fast cutting action and long service life across a variety of surfaces
• Resin bond shields the disc from heat damage to extend usable disc life in high-RPM applications
• Rated for both wet and dry sanding applications
• Maximum operating speed of 15,000 RPM

Compatibility

Designed for use with backup pads or steel platens that accept 2-inch PSA-style sanding discs in right-angle grinders, die grinders, and bench-mounted disc sanders.

Installation Notes

Installation is performed by pressing the adhesive face of the disc firmly onto a clean, dry backup pad or steel platen. Ensure the spindle speed of the tool does not exceed the disc rated maximum before mounting. Power down and disconnect the tool from its power source before mounting or removing the disc. Discs should be inspected for tears or edge damage before each use and replaced immediately if any defects are found.
