3M 7100138193 Scotch-brite Bristle Disc 3 in 80 Grit

Product Description

The 3M 7100138193 Scotch-Brite Bristle Disc is a 3-inch, 80-grit ceramic abrasive disc designed for surface preparation and finishing work on metal, painted, and coated surfaces. Built with molded, abrasive-filled flexible bristles and a proprietary ceramic abrasive grain, this disc delivers aggressive cutting action while conforming to contours and complex part geometries. It removes paint, rust, weld burns, heavy oxides, adhesives, and other surface contaminants efficiently. The curved disc profile increases surface contact compared to flat wire brushes, and the ceramic grain maintains consistent cutting performance throughout the full service life of the disc.

This disc is suited for metal fabrication, welding cleanup, and industrial surface prep applications in both shop and field environments. It performs well on flat and contoured workpieces, making it a practical choice for technicians handling deburring, coating removal, blending, and finishing tasks. The bristle spacing is optimized for high-loading substances, reducing clogging during use. Licensed tradespeople in mechanical, structural, and industrial maintenance trades typically reach for this disc when wire brushes lack the surface contact or leave safety concerns about wire filament breakage.

Key Features

• 3-inch diameter curved disc with 80-grit ceramic abrasive grain for aggressive, consistent material removal
• Molded, abrasive-filled flexible bristles conform to contours and complex geometries without heavy operator pressure
• Proprietary ceramic abrasive grain maintains cutting performance throughout the life of the disc
• Bristle spacing designed for coating removal and high-loading substance applications
• Contains no wire filaments, eliminating the risk of broken wire fragment hazards
• Suitable for stripping, deburring, blending, finishing, polishing, and cleaning operations

Compatibility

Designed for use with compatible right-angle grinders and rotary tools that accept 3-inch radial bristle disc attachments for surface preparation and finishing applications.

Installation Notes

This disc is installed and operated by machinists, fabricators, welders, and maintenance technicians using compatible angle grinders or rotary tools. Verify the tool's rated RPM does not exceed the disc's maximum operating speed before mounting. Always wear appropriate PPE including eye protection and gloves during operation. Inspect the disc for damage before each use and do not exceed the recommended operating speed.
