Osborn 0002674900 Knotted Wheel Brush 8 Inch Carbon Steel

Product Description

The OSBORN 0002674900 is a knotted wheel brush designed for aggressive surface preparation, weld cleaning, rust removal, and scale removal on metal workpieces. Built with carbon steel fill wire, this 8-inch diameter brush mounts via a 5/8-inch arbor hole and operates at a maximum rated speed of 8,500 RPM. The knotted wire configuration delivers greater abrasive force compared to crimped-wire brushes, making it well-suited for heavy-duty material removal on steel and iron substrates. It is installed and operated by fabricators, pipefitters, maintenance technicians, and welders working in industrial, construction, and mechanical trade environments.

This wheel brush is used on bench grinders, pedestal grinders, and arbor-mounted power tools where a 5/8-inch arbor is present. Typical applications include pre-weld surface prep, post-weld spatter and slag cleanup, removal of mill scale, corrosion, and coatings from ferrous metal surfaces. The 1-11/16-inch trim length and 5/8-inch face width concentrate wire contact for controlled, consistent work on both flat and contoured surfaces. No shank is included; the brush mounts directly to the arbor. This brush is not encapsulated.

Key Features

Compatibility

Designed for use on bench grinders and pedestal grinders equipped with a 5/8-inch arbor hole. Verify that the tool spindle speed does not exceed the 8,500 RPM rated maximum before use.

Installation Notes

Installation should be performed by a qualified technician following the grinder and brush manufacturer safety guidelines. Power down and lock out the grinder before mounting or removing the brush. Confirm arbor diameter matches the 5/8-inch bore and that all flanges and washers are properly seated before operation. Always operate at or below the 8,500 RPM maximum rated speed and wear appropriate personal protective equipment including eye and face protection.
