Norton 69957370138 Wheel Brush 4 in Stainless Steel 20000 Rpm

Product Description

The NORTON 69957370138 is a threaded-mount wheel brush designed for aggressive surface preparation, deburring, and cleaning on metal workpieces. The brush features a 4-inch outside diameter with a 0.5-inch face width and is filled with stainless steel wire in a standard twist knot configuration. It is rated to a maximum of 20000 RPM, making it suitable for use on high-speed angle grinders and die grinders equipped with a 5/8-11 threaded arbor. Stainless steel fill material resists corrosion and is appropriate for work on stainless steel or other surfaces where carbon steel contamination must be avoided. The 0.75-inch trim length provides consistent wire contact and controlled aggression across the work surface.

This wheel brush is used in fabrication shops, maintenance facilities, and field service settings where surface prep on metal components is required. Typical applications include weld seam cleanup, rust and scale removal, paint stripping, and edge deburring on ferrous and non-ferrous metals. The threaded mount and 5/8-11 arbor make it compatible with standard angle grinder tooling commonly found in HVAC, plumbing, and mechanical contracting shops for pipe and fitting preparation work.

Compatibility

Designed for use with angle grinders and die grinders fitted with a 5/8-11 threaded spindle. Verify that the grinder's no-load RPM rating does not exceed the 20000 RPM maximum rating of this brush before use.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with abrasive wheel safety. Always power down and disconnect the grinder before mounting or removing the brush. Thread the brush onto the 5/8-11 arbor securely before operation and confirm the tool RPM does not exceed the brush maximum rating. Eye protection and appropriate PPE are required when operating wire brushes at speed.
