3M 7010328455 Sanding Disc 6 Inch 180 Grit Aluminum Oxide

Product Description

The 3M 7010328455 is a 6-inch aluminum oxide sanding disc using a Stik-It pressure-sensitive adhesive attachment system. The disc mounts directly to a vinyl backup pad with firm hand pressure and peels off cleanly when the job is done, allowing fast disc changes without tools or hardware. The self-fracturing aluminum oxide mineral continuously exposes fresh cutting edges as it wears, maintaining cut rate and resisting loading across extended use. These discs are sold in packs and are sized for use with dual-action orbital sanders in finishing and surface-preparation workflows.

These discs are suited for automotive refinishing, bodywork, and general surface preparation. Common applications include sanding paint, primer, fiberglass, metal, and SMC panels. At 180 grit, the disc is positioned for finish sanding and final scratch refinement before topcoat. The Stik-It PSA backing is compatible with standard vinyl backup pads used in body shop and light fabrication environments.

Key Features

• Self-fracturing aluminum oxide mineral resists loading and maintains cut rate throughout disc life
• Stik-It PSA backing attaches with hand pressure and releases cleanly for fast disc changes
• Compatible with vinyl backup pads and dual-action orbital sanders
• 180 grit finish suitable for final surface preparation and pre-topcoat scratch refinement
• Works on paint, primer, fiberglass, metal, and SMC surfaces

Compatibility

Designed for use with vinyl backup pads and dual-action orbital sanders accepting 6-inch PSA-mount sanding discs.

Installation Notes

Align the disc squarely over the vinyl backup pad before applying pressure to seat the adhesive evenly. Ensure the orbital sander is powered off and unplugged before mounting or removing discs. Peel the disc at a low angle to avoid stretching or tearing the backing. Worn discs should be replaced before the mineral is fully depleted to prevent pad contact with the work surface.
