3M 7010029939 Sanding Disc 5 Inch P800 Grit

Product Description

The 3M 7010029939 is a 5-inch hook-and-loop coated abrasive sanding disc designed for precision surface finishing in professional trades and industrial applications. Built on a durable film backing, this disc uses aluminum oxide abrasive grain and features a multi-hole pattern for active dust evacuation without requiring hole alignment to the backing pad. The open-coat, load-resistant construction resists clogging and supports consistent cut rates across the disc's service life. At P800 grit, it is suited for fine finishing, between-coat sanding, and surface preparation work where a close-tolerance finish is required.

This disc is intended for use with 5-inch random orbital or orbital sanders equipped with hook-and-loop backup pads. P800 grit positions it for final-stage finishing tasks on painted surfaces, primer coats, body filler, wood, and composites in automotive, woodworking, and general fabrication environments. The multi-hole dust evacuation pattern is compatible with a range of pad hole configurations, eliminating the need to align disc holes with pad holes when changing discs. Each disc is sold individually and rated to 12,000 RPM.

Key Features

• Multi-hole pattern evacuates dust efficiently without requiring alignment to backing pad holes
• Open-coat, load-resistant aluminum oxide construction resists loading and clogging
• Durable film backing is tear-resistant and delivers a close-tolerance, consistent finish
• Hook-and-loop attachment allows fast disc changes and disc reuse
• Aluminum oxide grain cuts faster and lasts longer than traditional garnet abrasives
• Rated to 12,000 RPM for use with standard orbital and random orbital sanders

Compatibility

Designed for use with 5-inch hook-and-loop backup pads on random orbital and orbital sanders. Multi-hole pattern does not require alignment with pad holes, making it broadly compatible with standard 5-inch sanding pads across common pad configurations.

Installation Notes

Ensure the sander is powered off and unplugged before mounting or removing the disc. Press the disc firmly onto the hook-and-loop backup pad to ensure full contact across the abrasive surface. Do not exceed the 12,000 RPM maximum speed rating. Inspect the disc and backing pad for wear or damage before each use; replace if the film backing shows tears or the abrasive surface is loaded.
