3M 7100143047 Radial Bristle Brush Disc T-c 400 Grit

Product Description

The 3M 7100143047 is a replacement disc refill pack for the 3M Brite Radial Bristle Brush system, designed to extend the service life of radial bristle tools used in surface preparation and finishing. These discs are built for use on bench motors and similar rotary equipment, delivering consistent cleaning and light material removal with minimal applied pressure. The T-C designation indicates the disc configuration, and the 400 grit rating makes this refill suitable for fine cleaning, light deburring, and surface finishing work. Each pack includes a universal bench motor adapter for straightforward installation.

Radial bristle brushes are used across metalworking, maintenance, and fabrication environments wherever a safer, lower-risk alternative to wire brushes is required. The 7100143047 refill is appropriate for cleaning welds, removing light oxidation, and preparing surfaces before coating or inspection. Applications include HVAC fabrication shops, plumbing and mechanical contractors, and general industrial maintenance. The discs work on a range of base materials and coatings without the wire shedding and eye-hazard concerns associated with conventional wire wheel brushes.
