Norton 66252839036 Wheel Brush 4 in Stringer Bead Carbon Steel

Product Description

The NORTON 66252839036 is a stringer bead wire wheel brush designed for aggressive surface preparation, weld cleaning, and scale removal on metal workpieces. It uses coarse carbon steel filaments in a stringer bead configuration, which concentrates wire contact for deep cleaning action in tight weld grooves and seams. The wheel measures 4 inches in outside diameter with a 3/16 inch face width and a 7/8 inch trim length. Rated to 20000 RPM, this brush is built for use on angle grinders and compatible right-angle power tools. The threaded 5/8-11 arbor hole provides a secure, direct mount without a separate shank.

This wheel brush is suited for professional metalworking, fabrication shops, pipeline work, and structural steel applications where stringer bead weld cleaning is required. It performs well on mild steel surfaces and is a standard tool for ironworkers, pipefitters, and welders who need consistent, controlled wire contact along narrow weld beads. The coarse carbon steel fill handles heavy mill scale, rust, and post-weld spatter without loading. Sold individually; minimum order quantity is 10 units.

Compatibility

Designed for use on angle grinders and right-angle power tools with a 5/8-11 threaded spindle. Verify that the tool's rated no-load RPM does not exceed 20000 RPM before mounting.

Installation Notes

This brush is installed by a metalworker or fabricator onto a compatible angle grinder with a 5/8-11 spindle thread. Always power down and unplug or de-energize the tool before mounting or removing the brush. Wear appropriate PPE including face shield and gloves, as wire filaments can shed under load. Never exceed the rated maximum speed of 20000 RPM, and inspect the brush for damaged or missing wires before each use.
