3M 7010029923 Sanding Disc 5 Inch P320 Grit

Product Description

The 3M 7010029923 is a coated abrasive hook-and-loop sanding disc engineered for finish sanding applications. Built on a light A-weight paper backing, the disc uses aluminum oxide mineral to cut fast and hold up across a wide range of surfaces. Its multi-hole pattern is designed to evacuate sanding dust more efficiently than standard 5- or 6-hole configurations, which directly extends disc life and maintains cut rate throughout use. Open coat construction and a load-resistant coating work together to minimize clogging. The disc measures 5 inches in diameter and carries a P320 grit rating, placing it squarely in fine finishing work.

This disc is suited for finish sanding on wood, paint, primer, and similar surfaces in both residential and light commercial settings. The multi-hole dust extraction design makes it a practical choice when used with compatible vacuum-ready random orbital or orbital sanders on production finishing lines, cabinet shops, and automotive prep environments. The hook-and-loop attachment system allows quick pad changes and disc reuse, reducing downtime during multi-stage sanding operations.

Key Features

• Multi-hole pattern evacuates dust more effectively than 5- or 6-hole disc designs
• Open coat construction reduces loading and extends usable disc life
• Load-resistant coating helps maintain consistent cut rate throughout the disc lifespan
• Aluminum oxide mineral provides fast cutting and durability across varied surfaces
• A-weight paper backing suited for fine finishing applications
• Hook-and-loop attachment enables fast disc changes and disc reuse

Compatibility

Designed for use with hook-and-loop random orbital and orbital sander pads accepting 5-inch discs with multi-hole dust extraction port patterns.

Installation Notes

Installation of sanding discs does not require trade licensing, but safe operation requires confirming that the sander pad hole pattern aligns with the disc hole pattern for effective dust extraction. Ensure the sander is powered off and unplugged before attaching or removing the disc. Do not exceed the maximum RPM rating of the sanding tool when using coated abrasive discs.
