3M 7100138319 Bristle Disc 1 in 80 Grit Ceramic

Product Description

The 3M 7100138319 is a Scotch-Brite Roloc Bristle Disc designed for surface preparation work including stripping, deburring, blending, finishing, polishing, cleaning, and coating removal. The disc measures 1 inch in diameter and uses 80-grit ceramic abrasive grain blended with aluminum oxide. The abrasive is molded directly into flexible bristles, which means the cutting properties are maintained throughout the full life of the disc rather than degrading quickly as wire brush tools do. Licensed tradespeople and machinists use this disc on metal components, welds, and complex contoured surfaces where consistent finish quality is required.

This disc is suited for light industrial and maintenance applications where surface prep must be performed on irregular or contoured parts. The flexible bristle construction conforms to curves and recesses, producing uniform finishes even on complex geometries. It is commonly used in fabrication shops, maintenance facilities, and field service environments where a quick disc change-out between finishing steps is necessary. The Roloc attachment system allows the disc to mount and release rapidly on compatible right-angle die grinders and finishing tools.

Key Features

• Ceramic abrasive grain blended with aluminum oxide molded into flexible bristles for consistent cutting throughout disc life
• Bristles conform to contoured and complex surfaces for uniform surface finish results
• Bristle spacing optimized for coating removal and high-loading applications
• Performs stripping, deburring, blending, finishing, polishing, cleaning, and coating removal in one tool
• Roloc attachment system enables fast disc changes during multi-step finishing processes

Compatibility

Designed for use with Roloc-compatible right-angle die grinders and finishing tool mandrels that accept 1-inch diameter twist-on discs.

Installation Notes

Installation and removal of the disc requires a compatible Roloc mandrel mounted in a right-angle die grinder or similar pneumatic or electric finishing tool. Ensure the tool is fully powered down and depressurized before changing discs. Operators should wear appropriate eye protection and gloves when performing abrasive surface preparation work. Follow applicable workplace safety standards for abrasive tool use.
