Norton 66252842233 Stringer Bead Wheel Brush 4 in Ss

Product Description

The NORTON 66252842233 is a stringer bead wheel brush designed for weld cleaning, slag removal, and surface finishing on metal workpieces. Built with stainless steel fill wire at 0.020-inch diameter, it is suited for applications where carbon contamination from standard steel wire must be avoided. The brush mounts via a 5/8-11 threaded arbor and runs at up to 20,000 RPM, making it compatible with standard angle grinders used in fabrication and maintenance work. Welders, pipefitters, and metal fabricators use this brush to clean stringer weld beads between passes and on finished welds without introducing ferrous contamination to stainless or specialty alloy base metals.

This wheel brush is used in light industrial, fabrication shop, and field welding environments. The stringer bead profile, with a narrow 3/16-inch face width and 4-inch outside diameter, concentrates wire contact directly on weld beads for precise cleaning. It is appropriate for use on stainless steel, aluminum, and other non-ferrous or contamination-sensitive metals. Licensed welders, ironworkers, and metal finishing technicians are the primary installers and users of this tool.

Key Features

• Stainless steel fill wire resists corrosion and prevents ferrous contamination on sensitive base metals
• 0.020-inch wire diameter provides aggressive cleaning action on weld bead surfaces
• Narrow 3/16-inch face width targets stringer bead profiles precisely
• 5/8-11 threaded mount fits standard angle grinder spindles directly
• 20,000 RPM maximum speed rating supports high-speed grinder use
• 4-inch outside diameter keeps tool weight and bulk low for overhead and positional work

Compatibility

Designed as an OEM-style replacement or direct-use wheel brush for angle grinders with a 5/8-11 threaded spindle, which is the standard arbor size on most 4-inch and 4.5-inch angle grinders used in welding and fabrication.

Installation Notes

Installation and use should be performed by qualified welders or metal fabricators familiar with abrasive wheel safety. Always power down and disconnect the grinder before mounting or removing the brush. Verify the grinder spindle speed does not exceed the 20,000 RPM rated maximum before operating. Eye protection, face shield, and appropriate PPE are required; follow ANSI B11 and tool manufacturer safety guidelines when using wire wheel brushes at speed.
