3M 7100138296 Scotch-brite Bristle Disc 3 in 120 Grit

Product Description

The 3M 7100138296 is a Scotch-Brite Radial Bristle Disc engineered for aggressive surface preparation and finishing work. Built with proprietary ceramic abrasive grain molded directly into flexible bristles, this 3-inch disc delivers consistent cutting action from first use through the end of disc life. At 120 grit, it handles paint removal, rust, weld burns, heavy oxides, adhesives, stains, and general surface contamination. The curved bristle design conforms to contours and complex part geometry, making it practical for deburring, blending, cleaning, and coating removal across a range of materials. No wire filaments are present, reducing the risk of wire fragment hazard common with wire wheel brushes.

This disc is suited for use in metal fabrication, welding and weld cleanup, HVAC sheet metal work, plumbing rough-in prep, and general industrial maintenance. The flexible bristles apply consistent abrasive contact across flat, curved, and irregular surfaces with less operator pressure than conventional wire brushes. It is appropriate for both shop and field use wherever controlled surface prep is required ahead of coating, welding, or inspection.

Key Features

• Proprietary ceramic abrasive grain provides aggressive cutting and maintains finish consistency 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 geometry with less pressure than wire brushes
• Bristle spacing optimized for coating removal and high-loading surface contaminants
• Contains no wire filaments, eliminating wire fragment hazard associated with wire wheel brushes
• Curved disc profile increases surface contact area on contoured workpieces

Compatibility

Designed for use as a radial bristle disc on compatible right-angle grinders and die grinders accepting 3-inch abrasive disc accessories.

Installation Notes

Installation and operation should be performed by a qualified tradesperson familiar with abrasive tool safety. Ensure the grinder is rated for the disc size and operating speed before mounting. Disconnect or de-energize the tool before mounting or removing the disc. Always wear appropriate PPE including eye protection and gloves, and follow ANSI B7 abrasive product safety standards during use.
