3M 7010328454 Sanding Disc 6 Inch 400 Grit Aluminum Oxide

Product Description

The 3M 7010328454 is a 6-inch pressure-sensitive adhesive sanding disc designed for fast, efficient material removal on a wide range of surfaces. Built around a self-fracturing aluminum oxide abrasive mineral at 400 grit, the disc continuously exposes fresh cutting edges as it wears, extending useful life and maintaining consistent cut rate. The Stik-It attachment system uses a peel-and-place PSA backing that adheres firmly to compatible vinyl backup pads during use and releases cleanly when the job is done, keeping disc changes quick and minimizing downtime. These discs are suited for use by automotive refinishing technicians, body shop professionals, and trade-level finishing technicians.

These discs are intended for use on paint, primer, fiberglass, metal, and SMC (sheet molding compound) surfaces in automotive refinishing and light industrial finishing applications. They are compatible with dual-action orbital sanders and vinyl PSA backup pads. The 400-grit designation makes them appropriate for fine scuff sanding, surface prep before topcoat, and smoothing between finish stages. Discs are sold in pack quantities with a minimum order of 10 units.

Compatibility

Designed for use with vinyl PSA backup pads and dual-action orbital sanders; suitable for automotive refinishing and light industrial surface finishing applications requiring a 6-inch PSA disc.

Installation Notes

Installation is performed by pressing the PSA-backed disc firmly onto a clean, compatible vinyl backup pad mounted to a dual-action orbital sander. Ensure the backup pad surface is free of debris and adhesive residue before applying a new disc to maintain full contact and prevent disc slippage. Peel the disc off carefully after use to keep the backup pad surface intact for subsequent disc changes. Always follow the sander manufacturer's RPM rating for the disc size in use.
