3M 7000000764 Scotch-brite Bristle Disc 9/16 in 120 Grit

Product Description

The 3M 7000000764 Scotch-Brite Bristle Disc is a ceramic abrasive disc designed for surface preparation, cleaning, and finishing on metal and coated surfaces. Built with molded, abrasive-filled bristles and 3M ceramic abrasive grain, the disc delivers aggressive cutting action while conforming to contours and complex part geometries. At 9/16 inch with a 120 grit rating, it targets fine to medium surface conditioning tasks. The curved profile increases surface contact compared to flat wire brushes, making it well suited for trades that require consistent finish quality on irregular or contoured workpieces. HVAC technicians, pipefitters, and sheet metal workers are the typical end users for this type of disc.

This disc is used for removing paint, stains, adhesives, weld burns, rust, heavy oxides, and general surface contaminants from metal surfaces. Its flexible bristle design allows it to reach into recesses and follow curved profiles without gouging the base material. The disc is appropriate for light industrial and commercial maintenance applications where wire brush safety concerns are a factor, since it contains no wire filaments. It is suited for use with compatible rotary tools and right-angle die grinders in shop or field settings.

Key Features

• Proprietary ceramic abrasive grain delivers aggressive cutting and consistent finish quality throughout disc life
• Molded, abrasive-filled flexible bristles conform to contours and complex part profiles
• Removes paint, rust, weld burns, adhesives, heavy oxides, and surface contaminants
• Contains no wire filaments, reducing wire-fragment hazard during use
• Bristle spacing optimized for high-loading substances such as coatings and adhesives
• Requires less operator pressure than wire brushes for equivalent material removal

Compatibility

Designed as an OEM-style abrasive accessory for use with compatible rotary die grinders and power tools that accept 9/16 inch bristle disc arbor attachments.

Installation Notes

Installation and mounting should be performed by a qualified technician familiar with abrasive accessory safety. Verify that the tool spindle speed does not exceed the maximum rated RPM for the disc before operation. Wear appropriate PPE including eye protection and gloves. Inspect the disc for damage before each use and replace if bristles show excessive wear or deformation.
