This CGW 6" knot wire cup brush is built for high-impact cleaning on flat surfaces, making it a go-to tool for fabrication, oilfield, and industrial work. Designed for angle grinders with a 5/8"-11 spindle, it delivers fast material removal and long service life.
The twisted (knot) wire construction provides significantly more cutting action than crimped brushes, while maintaining durability under heavy pressure. Typical configurations use .020" carbon steel wire, which offers a strong balance of aggressiveness and control.
