Hangzhou Shapu Industrial Brush Co Ltd is based in China and lists industrial brushes on Global Trade Plaza. The knotted cup brush is designed for heavy-duty surface conditioning on large metal areas. It removes rust, corrosion, paint, spatter and scale, and is used to clean weld edges, deburr metal and prepare fabricated steelwork. The brush fits 4-1/2 inch angle grinders with a 5/8 inch arbor or 11 UNC standard thread. It is built with strengthened steel and a large hexagonal threaded arbor to reduce wire breakage during heavy work. Buyers can send an enquiry through Global Trade Plaza.
