3M 7100138286 Scotch-brite Roloc Bristle Disc 2 in 120 Grit

Product Description

The 3M 7100138286 is a Scotch-Brite Roloc Bristle Disc engineered for surface preparation tasks including stripping, deburring, blending, finishing, polishing, cleaning, and coating removal. At 2 inches in diameter and 120 grit, this disc combines proprietary ceramic abrasive grain with aluminum oxide in molded, flexible bristles. The construction provides more consistent surface contact than wire brushes and retains cutting action throughout the full life of the disc. It is suited for use by metalworkers, maintenance technicians, fabricators, and trade professionals working on complex or contoured parts.

This disc is used in applications where consistent surface finish quality is required across multiple steps. The flexible bristles conform to irregular or contoured surfaces, making it well suited for deburring machined parts, removing coatings and scale, and prepping surfaces for welding or painting. The Roloc attachment system allows fast disc changes during multi-step finishing operations without tools, reducing downtime on the job.

Key Features

• Molded, abrasive-filled bristles strip, deburr, blend, finish, polish, clean, and remove coatings
• Proprietary ceramic abrasive grain blended with aluminum oxide delivers consistent cut quality throughout disc life
• Bristle spacing optimized for coating removal and high-loading surface conditions
• Flexible bristles conform to contours for uniform finishes on complex geometry
• Roloc quick-change attachment system enables fast, tool-free disc swaps during multi-step processes
• Retains abrasive properties from first use to last, reducing frequency of disc changes

Compatibility

Designed for use with Roloc-compatible angle grinders, die grinders, and finishing tools that accept 2-inch Roloc threaded-hub discs.

Installation Notes

Installation and disc changes should be performed by qualified personnel familiar with angle grinder and die grinder safety practices. Power down and disconnect the tool from its power source before mounting or removing the disc. Verify the tool RPM rating does not exceed the disc maximum rated speed before operation. Eye protection, hearing protection, and appropriate gloves are standard PPE for abrasive disc operations.
