3M 7010308402 Psa Abrasive Disc 30 in 80 Grit Aluminum Oxide

Product Description

The 3M 7010308402 is a pressure-sensitive adhesive (PSA) abrasive disc designed for medium-duty grinding and surface preparation tasks. It measures 30 inches in diameter and uses 80-grit aluminum oxide abrasive to deliver consistent stock removal on metal, wood, and composite surfaces. The disc features an X-weighted cloth backing for added durability and flexibility under load, making it well-suited for high-contact sanding applications on bench-top motors and random orbital sanders. No vacuum holes are included. Installation and use require no additional fasteners beyond the PSA mounting surface. This disc is installed and used by metalworkers, fabricators, and finishing technicians in production and shop environments.

This disc is designed for use on bench-top motors and random orbital sanders in production shop and industrial finishing environments. The 30-inch diameter makes it appropriate for large-format sanding tables and disc grinder setups where consistent, even abrasion across a wide surface area is required. The PSA backing allows for quick disc changes directly onto compatible sanding platens. The flexible cloth construction conforms to slightly irregular or contoured workpieces, expanding its usefulness beyond flat-surface applications.

Key Features

Compatibility

Compatible with bench-top motors and random orbital sanders accepting 30-inch PSA-mount abrasive discs. Part of the 3M 348D series.

Installation Notes

PSA discs are installed by trade and industrial finishing technicians familiar with large-format sanding equipment. Before mounting, ensure the sanding platen is clean, dry, and free of adhesive residue from previous discs to ensure proper bond. Power down and lock out the machine before mounting or removing the disc. Do not exceed the maximum RPM rating of the sander or disc platen.
