Norton 66252839106 Wheel Brush 4 in Carbon Steel 20000 Rpm

Product Description

The NORTON 66252839106 is a stringer bead wheel brush designed for heavy-duty surface preparation, weld cleaning, and scale removal on metal workpieces. Built with coarse-grade carbon steel filaments, this brush mounts directly to angle grinders and bench grinders via a threaded 5/8-11 arbor hole. It runs at up to 20000 RPM, making it well-suited for fast, aggressive cleaning passes on steel, iron, and other ferrous surfaces. The 4-inch outside diameter and 1/2-inch face width deliver concentrated contact along narrow beads and seams. Licensed tradespeople in fabrication, welding, and pipefitting routinely specify this brush type for interpass weld cleaning and post-weld finishing.

This wheel brush is used in light industrial and commercial fabrication environments wherever weld spatter, rust, mill scale, or surface oxides need to be removed efficiently. The stringer bead wire configuration provides aggressive cutting action in tight grooves and along weld beads. It is appropriate for use on angle grinders fitted with a 5/8-11 spindle thread. No shank is included, so the tool must be threaded directly onto the grinder spindle.

Key Features

• Stringer bead wire configuration for aggressive action in grooves and weld seams
• Coarse-grade carbon steel fill for fast material removal on ferrous surfaces
• Threaded 5/8-11 arbor hole for direct spindle mounting — no shank required
• 4-inch outside diameter with 1/2-inch face width for concentrated contact
• Rated to 20000 RPM for use with standard angle grinders
• 1-inch trim length for consistent filament stiffness and wear life

Compatibility

Designed for use with angle grinders and bench grinders equipped with a 5/8-11 threaded spindle. Confirm the tool spindle speed rating meets or exceeds the brush maximum RPM rating before mounting.

Installation Notes

Installation and use should be performed by a qualified tradesperson familiar with abrasive wheel safety. Always power down and disconnect the grinder before mounting or removing the brush. Verify the spindle speed of the tool does not exceed the 20000 RPM maximum rating of the brush. Eye and face protection, along with appropriate PPE, is required during operation per ANSI B11 and OSHA abrasive wheel standards.
