3M 7010029933 Hookita Sanding Disc 5 Inch P320 Grit

Product Description

The 3M 7010029933 is a coated abrasive sanding disc designed for random orbital and hook-and-loop sanders used in surface preparation and finish sanding applications. This 5-inch disc uses aluminum oxide abrasive grain at P320 grit and features a proprietary multi-hole dust extraction pattern that evacuates sanding dust more efficiently than standard 5- or 6-hole designs. The result is a disc that resists loading, stays cooler, and maintains cut rate longer than conventional designs. An open-coat, load-resistant backing prevents clogging and supports consistent material removal through the life of the disc.

This disc is suited for fine sanding stages in wood finishing, automotive body prep, painted surfaces, and light metal work. The C-weight paper backing provides enough rigidity for aggressive surface work while remaining flexible enough for contoured panels. The Hookita hook-and-loop attachment system allows fast disc changes without tools, making it practical for shops and field technicians who rotate through multiple grits during a job. The multi-hole pattern requires no manual hole alignment when mounting.

Key Features

• Proprietary multi-hole pattern improves dust extraction over standard 5- or 6-hole disc layouts
• Open-coat, load-resistant coating reduces clogging and extends disc life
• Aluminum oxide grain cuts faster and lasts longer compared to traditional garnet abrasives
• C-weight paper backing supports aggressive sanding while maintaining flexibility
• Hookita hook-and-loop system allows tool-free disc changes and disc reuse

Compatibility

Designed for use with 5-inch hook-and-loop random orbital and orbital sanders that accept multi-hole sanding discs.

Installation Notes

Mounting requires a 5-inch hook-and-loop backup pad. Ensure the sander is powered off and unplugged before changing discs. Press the disc firmly and evenly onto the backup pad to ensure full hook engagement before operating the tool. Inspect the disc for damage or excessive wear before each use and replace when cut rate drops noticeably.
