Norton 66252838838 End Brush 1 in Stainless Steel Crimped Wire

Product Description

The NORTON 66252838838 is a crimped-wire end brush designed for surface preparation, deburring, cleaning, and blending on metal workpieces. The brush features a 1-inch diameter stainless steel fill rated to 22,000 RPM, making it suitable for use with die grinders and rotary tools operating at high speed. The 1/4-inch pilot shank attaches directly to standard die grinder collets, and the 1-1/2-inch shank length provides clearance for reaching into bores, ports, and recessed cavities. Coarse grade wire delivers aggressive material removal on ferrous and non-ferrous surfaces. This brush is used by HVAC technicians, pipefitters, plumbers, and general maintenance trades for cleaning pipe ends, heat exchanger tubes, and weld prep.

This end brush is suited for light-to-medium duty cleaning and surface conditioning tasks in residential and commercial maintenance environments. Typical applications include removing oxidation and scale from pipe fittings, cleaning burrs from drilled holes, and prepping weld joints on stainless or carbon steel. The stainless steel fill resists contamination transfer, making it appropriate for applications where carbon steel wire is not permitted, such as stainless piping systems or food-grade equipment service.

Key Features

• 1-inch brush diameter with coarse-grade stainless steel crimped wire fill
• 22,000 maximum RPM rating for use with die grinders and high-speed rotary tools
• 1/4-inch pilot shank fits standard die grinder collets without adapters
• 1-1/2-inch shank length for access to recessed areas and deep bores
• Stainless steel fill prevents carbon contamination on non-ferrous or stainless workpieces
• Crimped wire construction maintains consistent contact pressure across irregular surfaces

Compatibility

Designed for use with die grinders and rotary tools equipped with a 1/4-inch collet. Verify the tool's rated RPM meets or exceeds 22,000 RPM before mounting. Not piloted or bridled.

Installation Notes

Installation and use should be performed by a qualified tradesperson familiar with rotary abrasive tooling. Always confirm the die grinder is powered off and disconnected from the air supply or electrical source before mounting or removing the brush. Do not exceed the 22,000 RPM maximum speed rating marked on the brush. Eye protection and appropriate PPE are required when operating wire brushes at speed; wire filaments can break loose under load.
