3M 7100138295 Scotch-brite Bristle Disc 2 in 220 Grit Ceramic

Product Description

The 3M 7100138295 Scotch-Brite Radial Bristle Disc is a 2-inch diameter, 220-grit ceramic abrasive disc designed for surface preparation and finishing tasks in metal fabrication, maintenance, and industrial applications. The disc uses proprietary ceramic abrasive grain molded directly into flexible bristles, delivering aggressive cutting action and consistent finish quality from the first use through the end of the disc's service life. Unlike wire brushes, the abrasive-filled bristles require less operator pressure and conform to curved or contoured surfaces, making them well suited for complex geometry work. Licensed trades and industrial maintenance technicians are the primary installers and users of this product.

This disc is used in residential, commercial, and industrial settings for removing paint, rust, heavy oxides, weld burns, adhesives, stains, and other surface contaminants. The curved bristle design and 220-grit ceramic grain are suited for blending, deburring, finishing, polishing, and coating removal on metal and other hard surfaces. Applications include weld prep and post-weld cleanup, corrosion removal, and surface conditioning on flat and irregular workpieces. Its 2-inch diameter fits standard mandrel-mounted disc setups commonly used in angle grinders and die grinders.

Key Features

• 220-grit ceramic abrasive grain molded into bristles for aggressive, consistent cutting throughout disc life
• Flexible, curved bristles conform to contoured and complex part geometries with less pressure than wire brushes
• Bristle spacing optimized for coating removal and high-loading surface contaminants
• Contains no wire filaments, reducing risk of wire fragment ejection during use
• Strips, deburrs, blends, finishes, polishes, cleans, and removes coatings in a single tool
• 2-inch diameter suits compact angle grinders and die grinders with standard mandrel attachments

Compatibility

Designed for use with standard mandrel-mounted 2-inch disc setups on angle grinders and die grinders used in metal surface preparation and finishing applications.

Installation Notes

This disc is installed and operated by metal fabricators, maintenance technicians, and industrial trades personnel. Ensure the grinder or die grinder is powered off and unplugged before mounting or removing the disc. Follow the tool manufacturer's maximum RPM rating and verify the disc's rated speed is compatible before operation. Always use appropriate personal protective equipment including eye and face protection, as abrasive discs generate debris during use.
