3M 7000119439 Hook and Loop Abrasive Disc 5 Inch P320

Product Description

The 3M 7000119439 is a coated abrasive disc designed for fast cutting and close-tolerance finishing on wood, paint prep, and defect repair surfaces. It uses aluminum oxide grain on a flexible film backing that resists tearing better than comparable paper-backed products. The disc runs at up to 12000 RPM and measures 5 inches in diameter with a P320 grit rating. An open-coat construction and load-resistant coating keep debris from clogging the disc surface, sustaining cut rate through extended use. A hook and loop attachment system allows quick disc changes and reuse across the full service life of each disc.

This disc is suited for auto body shops, woodworking facilities, and finishing operations that demand consistent, repeatable surface quality at production volume. Typical applications include paint preparation, surface defect removal, and final finish sanding on wood and coated substrates. The film backing conforms to contoured surfaces better than rigid paper products, making it a practical choice for technicians working on curved panels or shaped components.

Key Features

• Aluminum oxide abrasive grain for fast cut rate and extended disc life
• Flexible film backing resists tearing and delivers a close-tolerance, consistent finish
• Open-coat construction increases aggressiveness and reduces loading
• Load-resistant coating prevents dust and debris buildup on the abrasive surface
• Hook and loop attachment allows easy disc changes and repeated reuse
• Rated to 12000 RPM for compatibility with high-speed random orbital and DA sanders

Compatibility

Designed for use with 5 inch hook and loop backing pads on random orbital and dual-action sanders commonly used in automotive finishing and woodworking applications.

Installation Notes

Mounting and removal requires no tools — press the disc firmly onto a clean, dry hook and loop backing pad before use. Ensure the sander is powered off and disconnected before changing discs. Inspect the backing pad for worn hooks that may reduce disc retention. Follow shop safety guidelines for dust collection and respiratory protection when sanding painted or coated surfaces.
