3M 7100077621 Sanding Disc 6 Inch P240 Grit

Product Description

The 3M 7100077621 is a coated abrasive hook-and-loop sanding disc engineered for aggressive material removal and extended disc life. At 6 inches in diameter with a P240 grit aluminum oxide abrasive, it is designed for finish sanding, surface prep, and stock removal on wood, paint, and composites. The multi-hole pattern evacuates dust more effectively than standard 5- or 6-hole discs, increasing cut rate and reducing disc loading. Rated to 12,000 RPM, this disc suits orbital and random-orbit sanders used in production and finishing environments.

This disc is suited for professional finishing work in woodworking shops, automotive refinishing, and general surface preparation. The open-coat, load-resistant construction keeps the abrasive cutting cleanly through fine sanding stages. The hook-and-loop backing allows fast disc changes without aligning pad holes, making it practical in high-throughput settings where downtime matters. It is sold per disc and is intended for tradespeople and finishing professionals who cycle through abrasives at volume.

Key Features

• Multi-hole pattern provides superior dust evacuation compared to standard 5- or 6-hole disc designs
• No hole alignment required with the disc pad, enabling fast and convenient disc changes
• Open-coat, load-resistant surface prevents clogging and extends usable disc life
• Durable film backing is tear-resistant and delivers a consistent, close-tolerance finish
• Aluminum oxide abrasive cuts faster and outlasts traditional garnet abrasives
• Rated to 12,000 RPM for use with standard random-orbit and orbital sanders

Compatibility

Designed for use with hook-and-loop 6-inch random-orbit and orbital sander pads. No hole alignment with the pad is required due to the multi-hole pattern design.

Installation Notes

Installed by pressing the hook-and-loop backing firmly onto a compatible 6-inch sanding pad. Confirm the sander is powered off and unplugged before changing discs. Do not exceed the 12,000 RPM speed rating. Inspect the disc for tears or loading before each use and replace if the abrasive is glazed or the backing is damaged.
