3M 7100077623 Sanding Disc 6 Inch P400 Aluminum Oxide

Product Description

The 3M 7100077623 is a coated abrasive hook-and-loop sanding disc engineered for dust-evacuating finish work. Built on a durable film backing, this 6-inch disc runs a multi-hole pattern that pulls dust away from the work surface more efficiently than standard 5- or 6-hole designs. The result is a cleaner cut, a longer-lasting disc, and a more consistent finish. Aluminum oxide abrasive grain delivers faster cutting action and greater durability compared to conventional garnet abrasives. Rated to 12000 RPM, it is suited for use with standard random-orbit and disc sanders in finishing applications.

This disc is intended for surface preparation and finish sanding tasks where dust control and consistent scratch patterns are critical. The P400 grit rating places it in the fine-finishing range, appropriate for final prep before sealing, painting, or coating on wood, composite, and similar substrates. Contractors, finish carpenters, cabinet installers, and auto-body technicians commonly use discs in this grit range. The open-coat, load-resistant mineral arrangement resists clogging, making this disc effective on materials that generate heavy sanding dust.

Key Features

• Multi-hole pattern provides superior dust extraction without requiring hole alignment to the pad
• Open-coat, load-resistant abrasive layer resists clogging and extends disc life
• Hook-and-loop attachment allows fast disc changes and disc reuse
• Durable film backing is tear-resistant and supports close-tolerance, consistent finishes
• Aluminum oxide grain cuts faster and lasts longer than traditional garnet abrasives
• Rated to 12000 RPM for compatibility with standard random-orbit sanders

Compatibility

Designed for use with 6-inch hook-and-loop random-orbit sander pads. The multi-hole pattern does not require alignment with pad holes, making it compatible with a wide range of disc pad configurations.

Installation Notes

Attachment and removal require no tools — press the disc firmly onto the hook-and-loop sander pad to seat it before use. Confirm the sander speed does not exceed the 12000 RPM disc rating before operation. Inspect the disc for tears, loading, or worn abrasive before each use and replace as needed. Disconnect the sander from power before changing discs.
