3M 7100138304 Radial Bristle Brush Disc T-c 120 Grit

Product Description

The 3M 7100138304 is a radial bristle brush replacement disc designed to clean, deburr, and finish metal surfaces without the hazards associated with wire brushes. The T-C configuration and 120 grit rating make it suited for light surface preparation and coating removal on ferrous and non-ferrous metals. Minimal pressure is required during operation, reducing operator fatigue and the risk of surface gouging. Each pack includes a universal benchmotor adapter, making it compatible with standard bench-mounted rotary tools. This disc is typically installed and operated by machinists, fabricators, maintenance technicians, and metal finishing professionals.

This replacement disc is used in metal fabrication shops, maintenance facilities, and light industrial settings where wire brush alternatives are preferred for safety or surface quality reasons. It works on a variety of coatings including rust, scale, and light corrosion. The 7-5/8 inch disc size is suited for bench motor applications where consistent, controlled finishing is required. The pack format is a practical choice for shops that run continuous surface prep operations and need ready replacement discs on hand.
