Weiler 94664 Knotted Wheel Brush 6 Inch Carbon Steel

Product Description

The WEILER 94664 is a knotted wire wheel brush designed for aggressive surface preparation, weld cleaning, and scale removal on metal workpieces. Built with carbon steel stringer bead twist wire, it mounts via a 5/8-11 threaded arbor and spins at up to 12,500 RPM. The 6-inch outside diameter and 3/16-inch face width concentrate cutting action into a narrow contact zone, making it effective for cleaning weld seams, deburring edges, and removing rust or mill scale. Fabricators, ironworkers, and maintenance technicians reach for this brush when a flap disc or grinder cup wheel is too broad for the task at hand.

This wheel brush is suited for use on angle grinders and bench grinders equipped with a 5/8-11 threaded spindle. Typical applications include structural steel fabrication shops, pipe fitting, heavy equipment maintenance, and industrial MRO environments where consistent weld bead cleanup and surface conditioning are part of the daily workflow. The knotted wire construction delivers a more aggressive cut than crimped wire, making it the right choice for heavy deposits of slag, spatter, or oxidation on carbon steel and iron substrates.

Key Features

Compatibility

Designed for use with angle grinders and bench grinders fitted with a 5/8-11 threaded spindle. Confirm the grinder's rated RPM meets or exceeds the brush maximum before mounting.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive tool safety. Always power down and disconnect the grinder before mounting or removing the brush. Verify the tool spindle speed does not exceed the brush maximum of 12,500 RPM before operation. Always wear face shield, safety glasses, and appropriate hand protection when operating knotted wire brushes, as wire filaments can break free during use.
