3M 7000046125 Scotch-brite Bristle Disc 9/16 in 400 Grit

Product Description

The 3M 7000046125 Scotch-Brite Radial Bristle Disc is a flexible abrasive disc designed for surface preparation, coating removal, and finishing work on metal and other hard substrates. Built with proprietary ceramic abrasive grain molded directly into flexible bristles, the disc maintains consistent cutting action from first use to last. At 9/16 inch with a 400 grit rating, it suits detail work and contoured surfaces where rigid abrasive tools lose contact. Tradespeople in metal fabrication, welding, HVAC sheet metal work, and general mechanical service install and use this disc for stripping paint, removing rust, weld burns, and heavy oxidation.

This disc fits applications requiring controlled surface prep on complex or contoured parts. The flexible bristles conform to irregular geometry, making it effective for deburring, blending, and cleaning areas that flat abrasive media cannot reach consistently. It is suited for use in residential and light commercial maintenance contexts as well as production metal finishing environments. The 400 grit ceramic formulation targets moderate surface conditioning without aggressive stock removal.

Key Features

• Ceramic abrasive grain molded into each bristle for consistent cut rate throughout disc life
• Flexible bristles conform to contours and complex part geometry with less applied pressure than wire brushes
• No wire filaments, reducing risk of wire fragment ejection during use
• Removes paint, rust, weld burns, heavy oxides, adhesives, and surface contaminants
• Bristle spacing designed for high-loading substances such as coatings and oxides
• Maintains abrasive property throughout disc service life, not just at initial use

Compatibility

Designed for use as a radial bristle disc on compatible rotary tools and mandrels accepting 9/16 inch bristle disc attachments.

Installation Notes

This disc is installed and operated by machinists, fabricators, HVAC sheet metal technicians, and maintenance trades. Always mount the disc on a mandrel rated for the disc size and confirm the tool RPM does not exceed the disc rating before operation. Wear appropriate eye protection and face shield, as abrasive discs generate debris during use. Inspect the disc for damage before each use and discard any disc showing cracked or missing bristles.
