3M 7000028529 Scotch-brite Bristle Disc 2 in 400 Grit

Product Description

The 3M 7000028529 Scotch-Brite Radial Bristle Disc is a 2-inch diameter, 400-grit ceramic abrasive disc designed for surface preparation, coating removal, and finishing work across metal, painted, and contoured surfaces. The disc uses proprietary ceramic abrasive grain molded directly into flexible bristles, which allows the abrasive property to remain consistent from first use through the end of the disc's life. It is commonly installed on angle grinders or rotary tools by maintenance technicians, fabricators, metalworkers, and trade professionals who need aggressive surface action without the safety risks associated with wire brushes.

This disc is suited for residential and commercial maintenance, fabrication shops, and field service applications where operators need to remove paint, stains, adhesives, weld burns, rust, heavy oxides, and general surface contaminants from large or complex areas. The curved bristle profile and flexible construction allow the disc to conform to irregular or contoured surfaces, making it practical for work on pipe, tubing, fittings, and structural components where flat abrasives cannot maintain consistent contact.

Key Features

• 400-grit ceramic abrasive grain delivers aggressive cutting with consistent finish quality throughout the disc's service life
• Flexible, abrasive-filled bristles conform to contoured and complex surfaces with less applied pressure than wire brushes
• Bristle spacing optimized for coating removal and high-loading substance clearance
• Contains no wire filaments, reducing hazard from wire fragment ejection during operation
• Curved disc geometry maintains surface contact across irregular profiles
• Effective for stripping, deburring, blending, finishing, polishing, cleaning, and coating removal in a single tool

Compatibility

Designed for use on angle grinders and rotary tools accepting 2-inch diameter accessory discs. Suitable for use on metal, painted surfaces, and other substrates requiring surface preparation or coating removal.

Installation Notes

Installation and operation should be performed by qualified technicians familiar with rotary abrasive tool safety. Confirm the tool's maximum RPM rating meets or exceeds the disc's rated speed before mounting. Power down and disconnect the tool from its power source before mounting or removing the disc. Operators should wear appropriate PPE including eye protection and gloves during use.
