3M 7100138171 Scotch-brite Roloc Bristle Disc 1 in 50 Grit

Product Description

The 3M 7100138171 is a Scotch-Brite Roloc Bristle Disc designed for surface preparation tasks including stripping, deburring, blending, finishing, polishing, cleaning, and coating removal. The disc combines a proprietary ceramic abrasive grain blended with aluminum oxide, molded directly into flexible bristles. At 1 inch in diameter and 50 grit, it delivers consistent material removal and finish quality from first use through the end of the disc's service life. The molded bristle construction provides more surface contact than wire brushes, making it well suited for aggressive prep work on metal and coated surfaces.

This disc is used in industrial, maintenance, and fabrication applications where surface finishing on tight geometries or complex contoured parts is required. The flexible bristles conform to irregular surfaces, producing repeatable results even on intricate components. The 50 grit ceramic AO blend is appropriate for coating removal, rust stripping, and light deburring on ferrous and non-ferrous metals. The Roloc attachment system allows rapid disc changes during multi-step finishing processes, reducing downtime between grits or operations.

Compatibility

Designed for use with Roloc-compatible right-angle grinders, die grinders, and finishing tools that accept 1 inch Roloc-style quick-change discs.

Installation Notes

Installation and disc changes should be performed with the tool powered off and disconnected from its power source.
