Norton 66253370022 Wheel Brush 4in Carbon Steel 20000 Rpm

Product Description

The NORTON 66253370022 is a threaded-mount wheel brush designed for aggressive surface preparation, deburring, and blending on metal workpieces. Built with carbon steel fill material, this 4-inch diameter brush delivers consistent abrasive action across a 3/16-inch face width. It is rated to a maximum of 20000 RPM, making it suitable for use on angle grinders and bench grinders operating at high speeds. Fabricators, welders, and maintenance technicians reach for this style of brush when removing mill scale, weld spatter, rust, or light burrs from steel and iron surfaces before finishing or inspection.

This wheel brush fits standard applications in metal fabrication shops, structural steel work, maintenance and repair facilities, and general industrial environments. The threaded arbor mount with a 5/8-11 thread size seats directly onto compatible angle grinder spindles without an adapter in most cases. It performs well on ferrous metals where a carbon steel fill is appropriate and where bristle contamination of the base material is not a concern. Package quantity is 1 brush per unit.

Compatibility

Designed for use on angle grinders and bench grinders with a 5/8-11 threaded spindle. Confirm the tool's rated free speed does not exceed the 20000 RPM maximum rating of this brush before installation.

Installation Notes

Installation and operation of wheel brushes should be performed by qualified personnel familiar with abrasive tool safety standards such as ANSI B7.1 and OSHA 29 CFR 1910.243. Always power down and disconnect the grinder before mounting or removing the brush. Inspect the brush for damaged or missing fill wires before each use and replace if any deformation is found. Wear appropriate PPE including eye protection and gloves during operation, and never exceed the marked maximum RPM.
