3M 7100138184 Radial Bristle Brush Disc 6 Inches 120 Grit

Product Description

The 3M 7100138184 is a radial bristle brush replacement disc designed for surface preparation, cleaning, and light finishing work. Built as a refill pack for compatible radial bristle brush assemblies, these discs feature a T-C configuration with a keyway mounting design and a 6-inch working width. The 120-grit construction allows for controlled material removal and surface cleaning with minimal applied pressure. A universal benchmotor adapter is included in the package, making the discs usable on standard bench-mounted finishing equipment. This product is sold in packs with a minimum quantity of 2.

These replacement discs are suited for metalworking, maintenance, and general surface prep tasks in trade and light industrial environments. They serve as a safer alternative to wire brushes when working on metal surfaces where wire contamination or aggressive abrasion is a concern. The bristle construction conforms to irregular surfaces and can remove light coatings, scale, and oxidation without damaging the base material. Technicians in HVAC, plumbing, and general mechanical trades commonly use radial bristle tools for pipe prep and component cleaning.
