3M 7100138293 Scotch-brite Bristle Disc 2 in 80 Grit Ceramic

Product Description

The 3M 7100138293 Scotch-Brite Radial Bristle Disc is a 2-inch diameter, 80-grit ceramic abrasive disc designed for surface preparation, coating removal, and finishing on metal and other industrial surfaces. Built with molded, abrasive-filled flexible bristles and a proprietary ceramic abrasive grain, it delivers aggressive cutting action and consistent finish quality from first use through the end of the disc's life. The curved bristle design conforms to contours and complex part geometries. Licensed trades and maintenance professionals use this disc for deburring, blending, rust removal, and surface cleaning tasks.

This disc is suited for residential and commercial maintenance, fabrication shops, and field service applications where surface prep speed and consistency matter. Typical uses include removing paint, stains, adhesives, weld burns, rust, heavy oxides, and other surface contaminants from large areas. The 80-grit ceramic construction provides an aggressive cut rate appropriate for stripping and initial surface preparation passes. It is commonly used by pipefitters, welders, HVAC technicians, and general maintenance tradespeople.

Key Features

• Proprietary ceramic abrasive grain delivers aggressive cutting and consistent finish throughout disc life
• Molded, abrasive-filled bristles strip, deburr, blend, finish, polish, clean, and remove coatings with less pressure than wire brushes
• Flexible bristles conform to contours and complex part geometries
• Bristle spacing optimized for coating removal and high-loading substance removal
• Contains no wire filaments, reducing risk of wire fragment ejection during use
• 2-inch diameter and curved profile suit tight spaces and contoured surfaces

Compatibility

Designed as an OEM-style replacement and standard-fit abrasive disc for angle grinders and rotary tools accepting 2-inch bristle disc mandrel arbors. No specific compatible model numbers were provided in the product data.

Installation Notes

This disc is installed and operated by tradespeople using compatible angle grinders or rotary power tools — confirm the tool's rated RPM meets or exceeds the disc's maximum operating speed before mounting. Wear appropriate PPE including eye protection and gloves before operation. Ensure the workpiece is secured and the tool is powered off and unplugged before mounting or removing the disc. Follow all applicable ANSI B7 and tool manufacturer safety standards for abrasive disc use.
