3M 7000028532 Scotch-brite Bristle Disc 3 in 400 Grit Ceramic

Product Description

The 3M 7000028532 Scotch-Brite Radial Bristle Disc is a 3-inch ceramic abrasive disc designed for surface preparation and finishing on metal, painted, and coated workpieces. Built with molded, abrasive-filled flexible bristles and a proprietary ceramic abrasive grain, this 400-grit disc delivers aggressive cutting action while maintaining consistent finish quality from first use to last. The curved profile allows the bristles to conform to irregular contours and complex part geometries. It is installed on angle grinders and die grinders by metalworkers, fabricators, and industrial maintenance technicians.

This disc is suited for removing paint, stains, adhesives, weld burns, rust, heavy oxides, and surface contaminants across large flat and contoured surfaces. The 400-grit ceramic construction makes it effective for both aggressive stock removal and controlled blending and finishing passes. Its flexible bristle design reduces the operator pressure required compared to conventional wire brushes, making it practical for extended surface prep work in fabrication shops, maintenance environments, and field service applications.

Key Features

• Proprietary ceramic abrasive grain delivers aggressive cutting and consistent finish quality throughout disc life
• Molded, abrasive-filled bristles strip, deburr, blend, finish, polish, clean, and remove coatings effectively
• Flexible bristles conform to contours and complex part geometries with less applied pressure than wire brushes
• Curved disc profile maximizes surface contact across flat and irregular workpieces
• Contains no wire filaments, reducing the risk of wire fragment ejection during use
• Bristle spacing is optimized for coating removal and high-loading surface contaminants

Compatibility

Designed as an OEM-style replacement and standard fitment for angle grinders and die grinders accepting 3-inch abrasive disc accessories.

Installation Notes

Installation and operation should be performed by qualified metalworkers or maintenance technicians familiar with abrasive disc safety practices. Confirm the grinder spindle speed rating meets or exceeds the disc maximum RPM before mounting. Power down and disconnect the tool from its power source before mounting or removing the disc. Always use appropriate eye, face, and hand protection when operating abrasive discs.
