3M 7010029939 Hook Loop Disc 5 in 1000 Grit Aluminum Oxide

Product Description

The 3M 7010029939 is a 5-inch hook and loop abrasive disc from the 3M 360L Series, designed for fine surface finishing and material removal on a wide range of substrates. It features a coated aluminum oxide abrasive at 1000 grit, which places it in the super fine grade category. The flexible backing allows the disc to conform to contoured surfaces, making it well-suited for detail sanding, surface prep, and finishing passes. Licensed trades and production professionals use this disc with random orbital sanders and other hook-and-loop compatible tools to achieve consistent, controlled scratch patterns before final finishing or coating application.

This disc is used in finishing operations across automotive refinishing, metalworking, woodworking, and general surface preparation applications. The 1000 grit aluminum oxide construction makes it appropriate for final sanding stages where a smooth, uniform surface profile is required prior to priming or topcoat application. The hook and loop attachment system allows for fast disc changes during production work, minimizing downtime. It is sold individually but requires a minimum order quantity of 100 units per order.

Key Features

• 1000 grit super fine aluminum oxide abrasive for final finishing passes

Compatibility

Designed for use with 5-inch hook and loop random orbital sanders and finishing tools that accept standard 5-inch abrasive discs.

Installation Notes

Install and remove the disc only when the sander is powered off and disconnected from its power source or air supply. Ensure the backing pad is clean and free of debris before attaching the disc to maintain secure hook and loop contact. Inspect the disc before each use and discard if torn, worn, or if abrasive material is loading excessively. Follow applicable workplace safety guidelines for respiratory protection and dust collection when sanding.
