3M 7100135085 Scotch-brite Bristle Disc 1 Inch 400 Grit

Product Description

The 3M 7100135085 Scotch-Brite Radial Bristle Disc is a flexible abrasive disc engineered for surface preparation tasks including paint removal, rust stripping, oxide removal, weld burn cleanup, and adhesive removal. Built with proprietary ceramic abrasive grain molded directly into flexible bristles, the disc delivers aggressive cutting action and maintains consistent finish quality from first use through the end of disc life. At 1 inch in diameter with a 400 grit rating, it is sized for detail work and tight areas. Licensed trade professionals and industrial maintenance technicians are the primary users.

This disc is suited for metal surface preparation in light industrial, maintenance, and fabrication environments. Its curved, flexible bristle design allows it to conform to contoured and complex part geometries, making it effective on tubing, weld seams, fittings, and irregular surfaces. It handles high-loading substances such as coatings, adhesives, and heavy oxides without the wire filament hazards associated with conventional wire brushes. It is used as a hand-tool or angle grinder attachment depending on the arbor configuration.

Key Features

• Proprietary ceramic abrasive grain provides aggressive cutting with consistent finish throughout disc life
• Flexible, abrasive-filled bristles conform to contours and complex part geometries with less pressure than wire brushes
• Removes paint, rust, weld burns, heavy oxides, adhesives, and surface contaminants
• Bristle spacing optimized for high-loading coating removal applications
• Contains no wire filaments, reducing wire fragment hazard during operation
• 400 grit ceramic construction supports stripping, deburring, blending, finishing, polishing, and cleaning in one disc

Compatibility

Designed for use as a radial bristle disc on rotary tools and angle grinders compatible with 1-inch diameter abrasive disc accessories.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with abrasive tool safety. Verify that the tool RPM rating meets or exceeds the disc RPM rating before mounting. Always power down and disconnect the tool from its power source before mounting or removing the disc. Wear appropriate PPE including eye protection and gloves during operation, and confirm workpiece is secured before contact.
