3M 7000118880 Psa Cloth Disc 348D 3 Inch 60 Grit Ao

Product Description

The 3M 7000118880 is a pressure-sensitive adhesive (PSA) cloth sanding disc in the 348D series, designed for aggressive material removal on metal, wood, and composite surfaces. The disc measures 3 inches in diameter and carries a 60 grit aluminum oxide abrasive bonded with a resin system that resists heat buildup during extended use. An X-weight cloth backing provides the structural rigidity needed for high-load grinding and finishing passes. Licensed abrasive technicians, metalworkers, and fabricators typically deploy this disc on random-orbital and disc-finishing tools rated up to 10000 RPM.

This disc is suited for both wet and dry sanding applications in fabrication shops, metal finishing operations, and surface preparation workflows. The PSA backing mounts directly to a compatible backup pad or steel platen without mechanical fasteners, allowing fast disc swaps during production runs. It is well-matched to applications requiring consistent scratch patterns before painting, coating, or inspection. The 60 grit cut rate makes it appropriate for stock removal and blending rather than final finishing passes.

Key Features

• Pressure-sensitive adhesive backing bonds securely to backup pads or steel platens and releases cleanly for fast replacement
• X-weight cloth backing withstands aggressive stock removal without tearing or edge fraying
• Aluminum oxide abrasive delivers fast cut rates and long service life across metal, wood, and composite substrates
• Resin bond system dissipates heat, extending disc life in continuous-duty applications
• Compatible with wet and dry sanding setups, adding workflow flexibility
• Rated to 10000 RPM for use on standard disc-finishing and random-orbital equipment

Compatibility

Designed for use with PSA-style backup pads and steel platens on disc finishing tools and random-orbital sanders rated up to 10000 RPM. No specific equipment model compatibility was provided in the product data.

Installation Notes

Power down and disconnect the sanding tool from its power source before mounting or removing discs. Align the disc concentrically on the backup pad or platen and apply firm, even hand pressure across the full face to ensure full PSA contact before operation. Verify the tool's rated RPM does not exceed the 10000 RPM maximum disc rating prior to use. Worn or contaminated backup pad surfaces reduce adhesion and should be cleaned or replaced before mounting a new disc.
