3M 7010292680 Psa Disc Roll 120 Grit 6 Inch 75 Discs

Product Description

The 3M 7010292680 is a pressure-sensitive adhesive (PSA) abrasive disc roll designed for surface preparation and finishing work with random orbital sanders. Each roll contains 75 discs, 6 inches in diameter, coated with aluminum oxide abrasive in a fine 120-grit grade. The gold-colored film backing carries an E-weight designation, which indicates a heavier, more durable backing suited to production sanding tasks. No vacuum holes are included, making these discs appropriate for solid backing pads. The flexible construction conforms to the work surface for consistent scratch patterns. This roll is used by trades and finishing professionals who need a reliable supply of PSA discs on a single-use, peel-and-stick basis.

These discs are intended for use with random orbital sanders in applications that call for fine material removal, surface blending, or prep work before coating or finishing. The 120-grit aluminum oxide abrasive is well matched to wood, painted metal, and composite surfaces where a smooth, consistent finish is required prior to priming or topcoating. The roll format supports high-volume work, reducing downtime from frequent restocking. The 6-inch diameter is a standard size compatible with common random orbital sanding tools used in construction, finishing, and light fabrication settings.

Compatibility

Designed for use with random orbital sanders accepting 6-inch PSA-style discs and solid (non-vacuum) backing pads. Part of the 3M 225L series.

Installation Notes

PSA discs are installed by peeling the release liner and pressing the disc firmly onto a clean, dry backing pad. Ensure the backing pad is free of adhesive residue from previous discs before applying a new disc, as contamination will reduce adhesion and cause disc slippage during use. Operate the sander according to the tool manufacturer's recommended speed range for the disc diameter. Inspect the disc for tears or uneven wear and replace before continuing if damage is found.
