3M 7100077549 Sanding Disc 5 Inch P400 Grit Ao

Product Description

The 3M 7100077549 is a coated abrasive hook-and-loop sanding disc engineered for high-efficiency dust evacuation during finish sanding operations. The disc uses a precision multi-hole pattern that outperforms standard 5- or 6-hole designs, pulling dust away from the work surface to maintain cut rate and extend disc life. At 5 inches in diameter and P400 grit, it delivers a close-tolerance, consistent finish on wood, composites, and painted surfaces. The aluminum oxide abrasive grain cuts faster and lasts longer than garnet alternatives. Rated to 12000 RPM, this disc is suited for use with random orbital sanders in production and finishing environments.

This disc is designed for finish sanding applications in woodworking, automotive bodywork, and light metal prep. The open-coat, load-resistant surface resists clogging when working with resins, sealers, or soft materials. The multi-hole dust evacuation pattern does not require alignment with the sanding pad holes, allowing fast disc changes without stopping to orient the disc. Licensed contractors, finish carpenters, auto body technicians, and production shop workers are the primary installers and users of this product.

Key Features

• Precision multi-hole pattern provides superior dust extraction without requiring hole alignment
• Open-coat, load-resistant abrasive coating resists clogging and maintains consistent cut rate
• Hook-and-loop attachment allows fast, tool-free disc changes and disc reuse
• Durable film backing is tear-resistant and supports close-tolerance finish work
• Aluminum oxide grain cuts faster and outlasts traditional garnet abrasives
• Rated to 12000 RPM for use with standard random orbital sanders

Compatibility

Designed as a hook-and-loop replacement disc for 5-inch random orbital sanders and sanders equipped with compatible hook-and-loop backup pads.

Installation Notes

This disc is installed by hand onto a compatible hook-and-loop sanding pad — no tools required. Ensure the sander is powered off and unplugged before changing discs. Do not exceed the 12000 RPM speed rating. Inspect the backup pad for worn hook material before attaching a new disc, as a worn pad reduces holding force and can cause disc separation during operation.
