3M 7100031692 5 Inch 150 Grit Hook and Loop Abrasive Disc

Product Description

The 3M 7100031692 is a coated abrasive disc designed for surface finishing, paint preparation, and defect repair work on wood and painted surfaces. Built on a flexible film backing with aluminum oxide abrasive grain, the disc delivers a fast cut rate alongside a uniform, close-tolerance finish. The film backing offers greater tear resistance than comparable paper-backed discs, making this product well suited to high-production environments where disc longevity matters. A load-resistant coating prevents dust and debris from clogging the abrasive surface during use. The disc mounts via a hook-and-loop attachment system, allowing fast change-outs without tools.

This disc is used in body shop, woodworking, and surface prep applications where consistent scratch patterns and finish quality are required. Open coat construction gives the disc a more aggressive cut profile, helping reduce loading when working with soft materials, paint, or wood resins. At 5 inches in diameter and rated to 12,000 RPM, it fits standard 5-inch random orbital and DA sanders commonly used in automotive refinishing and finish carpentry environments. The minimum order quantity is 4 units, sold by the box.

Key Features

• Aluminum oxide abrasive grain provides fast cut rate and long service life across wood and painted surfaces
• Flexible film backing delivers a close-tolerance, consistent finish with greater tear resistance than paper
• Hook-and-loop attachment enables fast disc changes and allows reuse throughout the life of the disc
• Open coat construction supports aggressive material removal and reduces loading
• Load-resistant coating minimizes clogging from dust and debris during high-production use

Compatibility

Designed for use with 5-inch hook-and-loop random orbital and dual-action sanders rated to a minimum of 12,000 RPM.

Installation Notes

This disc is installed and removed by hand using the hook-and-loop fastening system — no tools required. Ensure the sander backing pad is clean and free of debris before attaching the disc to maintain full contact and consistent finish quality. Verify the sander RPM rating meets or exceeds the disc speed rating before operation. Inspect the disc for tears or worn abrasive before each use and replace as needed.
