Norton 66252838887 End Brush 1 in Stainless Steel Knotted Wire

Product Description

The NORTON 66252838887 is a knotted wire end brush designed for aggressive surface preparation and cleaning on metal workpieces. Built with stainless steel fill wire in the coarse grade, it handles rust removal, weld spatter cleanup, scale removal, and surface conditioning on stainless or corrosion-sensitive substrates where carbon steel contamination must be avoided. The brush runs at up to 22,000 RPM and mounts via a 1/4-inch diameter steel shank, making it compatible with die grinders and rotary tools used throughout fabrication, welding, and mechanical service work. Licensed tradespeople and skilled fabricators are the primary installers.

This end brush is suited for tight access areas, inside bores, pipe ends, weld joints, and confined surface areas where a cup or wheel brush cannot reach. The knotted wire construction delivers high-impact scrubbing action appropriate for heavy deposits on steel, stainless steel, and similar hard metals. At 1 inch brush diameter with a 1-1/2 inch shank length, it fits standard die grinder collets and is commonly used in industrial maintenance, HVAC sheet metal work, pipe fitting, and structural steel fabrication.

Installation Notes

Installation is performed by machinists, fabricators, pipefitters, welders, or HVAC technicians using a die grinder or compatible rotary tool. Always confirm the tool's rated speed meets or exceeds the brush maximum RPM before mounting. Wear appropriate PPE including face shield and gloves when operating wire brushes at speed. Inspect the brush for damaged or splayed wires before each use and replace if wire integrity is compromised.
