Value Collection S04185856 Cup Brush 4-3/8 in Knotted Steel

Product Description

The VALUE COLLECTION S04185856 is a knotted steel cup brush designed for aggressive surface preparation on metal, welds, and castings. At 4-3/8 inches in diameter with a 0.02-inch wire diameter and single-row construction, it delivers focused scrubbing action for rust removal, scale stripping, and paint or coating removal. The threaded 5/8-11 arbor hole mounts directly to standard angle grinders. Rated to 6,500 RPM maximum, this medium-grade brush is built for sustained use in fabrication, maintenance, and industrial cleaning applications. It is sold individually.

This cup brush is suited for metalworking trades, maintenance technicians, and fabrication shops that require fast material removal from ferrous surfaces. Typical applications include weld spatter cleanup, corrosion removal from structural steel, surface prep before welding or coating, and deburring on pipe ends and plate. The single-row knotted fill pattern concentrates wire tension for more aggressive cutting action compared to crimped fill brushes of the same diameter.
