3M 7100077548 Sanding Disc 5 Inch P320 Grit

Product Description

The 3M 7100077548 is a 5-inch coated abrasive sanding disc designed for use with hook-and-loop disc pads on random orbital sanders. It features a precision multi-hole pattern that evacuates dust more effectively than standard 5- or 6-hole disc designs, resulting in faster cut rates and extended disc life. The aluminum oxide abrasive grain cuts aggressively and outlasts traditional garnet abrasives. Rated at 12000 RPM, this disc is suited for finish sanding tasks on wood, composites, and painted surfaces. Licensed HVAC techs, finish carpenters, auto body technicians, and general contractors reach for this disc when consistent, close-tolerance surface prep is required.

This disc is intended for finish sanding applications where dust control and surface quality are priorities. The P320 grit makes it appropriate for final-stage material removal and surface prep before coating or finishing. The open-coat, load-resistant construction resists clogging, which is especially useful when sanding resins, soft woods, or previously painted surfaces. The hook-and-loop attachment system allows fast disc changes without tools, supporting high-volume production environments or repetitive field work.

Key Features

• Precision multi-hole pattern provides superior dust extraction without requiring hole alignment to the pad
• Open-coat, load-resistant abrasive coating resists clogging and extends usable disc life
• Aluminum oxide grain cuts faster and lasts longer than garnet abrasives
• Durable film backing is tear-resistant and supports close-tolerance, consistent finish quality
• Hook-and-loop attachment allows quick disc changes and disc reuse
• 12000 RPM rating supports use on standard random orbital sanders

Compatibility

Designed for use with 5-inch hook-and-loop disc pads on random orbital sanders. The multi-hole pattern does not require alignment with pad holes, making it compatible with a wide range of standard pad configurations.

Installation Notes

Ensure the sander is powered off and unplugged before changing discs. Press the disc firmly onto the hook-and-loop pad to ensure full contact before operating. Do not exceed the rated 12000 RPM. Inspect the disc for tears or loading before each use and replace as needed.
