3M 7100138341 Radial Bristle Brush Disc 220 Grit

Product Description

The 3M 7100138341 is a radial bristle brush replacement disc designed for surface preparation and cleaning work in trade and industrial applications. The disc mounts to a bench motor using the included universal benchmotor adapter and delivers consistent abrasive action at 220 grit without requiring heavy hand pressure. It serves as a direct alternative to wire brushes, reducing the risk of wire fragment ejection during operation. HVAC technicians, plumbers, electricians, and metal fabricators use this disc to clean pipe ends, fittings, metal surfaces, and similar workpieces before joining or coating operations.

This replacement disc is suited for removing light coatings, oxidation, mill scale, and surface contaminants from metal, plastic, and composite substrates. The radial bristle design conforms to irregular surface profiles, making it effective on threaded fittings, flanges, and contoured parts. The 220 grit rating produces a fine finish appropriate for pre-treatment and light deburring tasks. The disc is packaged as a refill unit and works with standard radial bristle brush assemblies that accept T-C style replacement discs.
