3M 7100031684 Hook and Loop Disc 5 Inch P400 Grit

Product Description

The 3M 7100031684 is a hook-and-loop abrasive disc engineered for fast cut rates and close-tolerance finishing on wood, paint prep, and defect repair. Built on a flexible film backing, this 5-inch disc carries aluminum oxide abrasive at P400 grit and is rated to 12000 RPM. The film substrate resists tearing better than comparable paper-backed discs, making it a practical choice for high-production finishing work. An open-coat construction keeps the abrasive aggressive, while a load-resistant coating prevents dust and debris from clogging the disc surface during extended use.

This disc is suited for automotive paint prep, wood finishing, and surface defect repair in both shop and field environments. The hook-and-loop attachment system allows quick disc changes and permits reuse of the disc for the full span of its service life, reducing changeover time in production settings. The P400 grit level is appropriate for fine finishing passes where surface uniformity and minimal scratch depth are priorities.

Key Features

• Aluminum oxide abrasive grain delivers fast cut, long service life, and consistent surface finish
• Flexible film backing resists tearing and produces a close-tolerance, uniform finish
• Open-coat construction maintains an aggressive cut throughout the disc life
• Load-resistant coating reduces clogging from dust and debris
• Hook-and-loop attachment allows fast disc changes and supports disc reuse
• Rated to 12000 RPM for compatibility with standard random orbital and disc sanders

Compatibility

Designed for use with 5-inch hook-and-loop backing pads on random orbital sanders and disc sanders rated to a minimum of 12000 RPM.

Installation Notes

Verify the backing pad is clean and free of debris before attaching the disc to ensure full hook-and-loop engagement. Confirm the sander RPM rating meets or exceeds the disc maximum of 12000 RPM before operation. Inspect the disc for tears or damage before each use and remove from service if the abrasive layer or film backing is compromised.
