3M 7010029924 Hookit 216U Disc 5 Inch P400 Grit

Product Description

The 3M 7010029924 is a Hookit 216U coated abrasive disc engineered for clean sanding and finishing applications. Measuring 5 inches in diameter and rated at P400 grit, this disc uses aluminum oxide mineral bonded to a lightweight A-weight paper backing. A proprietary multi-hole pattern improves dust extraction beyond what standard 5- or 6-hole disc designs provide, keeping the work surface cleaner and reducing airborne particulate. Open coat construction combined with a load-resistant coating limits clogging, which extends disc life and maintains consistent cut rate throughout use. The Hookit hook-and-loop attachment system allows fast disc changes without tools.

This disc is suited for finish sanding on wood, composites, and painted surfaces in residential and light commercial woodworking, cabinetry, and refinishing environments. The P400 grit rating targets final-stage material removal and surface prep before topcoat application. The multi-hole dust extraction pattern is designed to work with compatible random orbital sanders equipped with vacuum or dust collection ports, reducing cleanup time and improving visibility of the work surface during finishing passes. Installers and finishing technicians working in low-tolerance surface prep will find the open coat construction particularly effective at extended intervals between disc changes.

Key Features

• Proprietary multi-hole pattern evacuates dust more effectively than standard 5- or 6-hole disc layouts
• Open coat construction reduces material loading and extends usable disc life
• Load-resistant coating maintains cut consistency and prevents premature glazing
• Aluminum oxide mineral delivers durable, fast-cutting performance across a range of surfaces
• Lightweight A-weight paper backing is appropriate for finish-stage sanding
• Hookit hook-and-loop system enables tool-free disc swaps and disc reuse

Compatibility

Designed for use with Hookit-compatible random orbital and orbital sanders equipped with multi-hole dust extraction vacuum ports. Verify sander hole pattern alignment before use to ensure proper dust evacuation performance.

Installation Notes

Attachment and removal require no tools — press the disc firmly onto the Hookit pad to seat the hook-and-loop interface fully before operation. Power down and disconnect the sander from any power source before changing discs. Inspect the backing pad for wear or debris that could prevent proper disc seating. Always connect to an appropriate dust collection system when sanding to comply with applicable workplace air quality and safety requirements.
