3M 7100138301 Radial Bristle Brush Disc 80 Grit 6 in 40pk

Product Description

The 3M 7100138301 is a Scotch-Brite Radial Bristle Brush Replacement Disc designed for surface conditioning, finishing, and contaminant removal on metal and other materials. This T-C 80 grit disc measures 6 inches in diameter and is sold in cartons of 40 discs. The abrasive bristles are made from aluminum oxide blended with 3M Ceramic Abrasive Grain, producing a mineral that is harder and longer-lasting than standard aluminum oxide alone. HVAC technicians, metalworkers, fabricators, and maintenance professionals use these discs to clean, deburr, and finish surfaces without the wire-ejection hazards associated with wire brushes.

These replacement discs are suited for general industrial, aerospace, automotive, metalworking, and transportation applications. They also serve fine-detail work in electronics, jewelry, and woodworking. The flexible bristles conform around protrusions, detail grooves, and hard-to-reach areas, making them effective for both flat and irregular surfaces. Compatible with radial bristle brush arbors that accept T-C style replacement discs, these are a direct consumable refill for existing brush assemblies already in service.
