3M 7010029942 Hookit 360L Disc 5 Inch P320 Grit Ao

Product Description

The 3M 7010029942 is a Hookit 360L coated abrasive sanding disc designed for professional surface preparation and finishing work. Built on a durable film backing, it uses aluminum oxide abrasive grains and an open-coat, load-resistant construction to resist clogging and maintain consistent cut rate through the life of the disc. The multi-hole dust evacuation pattern removes material from the work surface more effectively than standard 5- or 6-hole disc designs, extending disc life and improving finish quality. At 5 inches in diameter with a P320 grit rating, it is suited for fine finishing passes on wood, metal, and composite surfaces. Maximum operating speed is 12000 rpm.

This disc is used in automotive, woodworking, metal fabrication, and general surface finishing applications where consistent scratch pattern and dust control are priorities. The Hookit attachment system allows fast disc changes without alignment of pad holes to disc holes, reducing downtime during high-volume finishing operations. It is appropriate for use with compatible 5-inch random orbital and orbital sanders equipped with Hookit-style hook-and-loop backing pads. Licensed trades and finish professionals in body shop, millwork, and light industrial environments are the primary installers and users.

Key Features

• Multi-hole dust evacuation pattern outperforms standard 5- or 6-hole designs for better extraction and longer disc life
• Open-coat, load-resistant construction resists clogging on resinous or soft materials
• Hookit hook-and-loop attachment allows fast disc changes without hole alignment
• Durable film backing is tear-resistant and delivers a close-tolerance, consistent finish
• Aluminum oxide abrasive grains cut faster and outlast traditional garnet abrasives
• P320 grit rating suited for fine material removal and surface prep before finishing coats

Compatibility

Designed for use with 5-inch Hookit-compatible hook-and-loop sanding pads on random orbital and orbital sanders rated for use with coated abrasive discs up to 12000 rpm.

Installation Notes

Attach the disc to a compatible 5-inch Hookit backing pad by pressing firmly until the hook-and-loop interface is fully engaged. Confirm the sander is disconnected from power or air supply before mounting or removing discs. Do not exceed the 12000 rpm maximum operating speed marked for this disc. Inspect the disc and backing pad for wear or damage before each use and replace if the abrasive layer or film backing shows tearing.
