3M 7100077547 Sanding Disc 5 Inch P220 Aluminum Oxide

Product Description

The 3M 7100077547 is a 5-inch hook-and-loop coated abrasive sanding disc engineered for dust-free surface preparation. Built on a durable film backing, it uses aluminum oxide abrasive grain and features a precision multi-hole pattern that evacuates dust more effectively than standard 5-hole or 6-hole disc designs. The open-coat, load-resistant surface resists clogging, which sustains cut rate and extends disc life over repeated passes. The multi-hole layout does not require alignment with the backing pad, so disc changes are fast and straightforward. Rated to 12000 RPM. Intended for use by finishing carpenters, auto body technicians, and other tradespeople working with orbital sanders.

This disc is suited for fine finishing applications requiring consistent, close-tolerance surface profiles. The P220 grit makes it appropriate for final sanding passes on wood, primer, filler, and similar substrates before coating or paint application. The hook-and-loop attachment system allows the disc to be removed and reused across multiple sessions, reducing material waste on the job. Typical applications include cabinetry, furniture finishing, drywall feathering, and light metal prep in both shop and field environments.

Key Features

• Precision multi-hole pattern improves dust evacuation over standard 5-hole and 6-hole designs without requiring hole alignment to the pad
• Open-coat, load-resistant abrasive coating resists clogging and maintains consistent cut rate throughout disc life
• Aluminum oxide grain cuts faster and lasts longer compared to garnet abrasives
• Durable film backing is tear-resistant and supports a close-tolerance, consistent surface finish
• Hook-and-loop attachment allows for quick disc changes and disc reuse
• Rated to 12000 RPM for compatibility with standard random-orbital and orbital finishing sanders

Compatibility

Designed for use with 5-inch hook-and-loop random-orbital sanding pads. The multi-hole pattern does not require alignment with backing pad hole configurations.

Installation Notes

Ensure the sander is powered off and disconnected from any power source before attaching or removing the disc. Press the disc firmly and evenly onto the hook-and-loop backing pad to ensure full adhesion before operation. Do not exceed the rated speed of 12000 RPM. Inspect the disc before each use and discard if torn, loaded, or delaminated.
