Description
The FORNEY INDUSTRIES INC 72759 is a 4-inch twist knot wire wheel brush designed for heavy-duty surface preparation and cleaning applications. Built with a coarse wire configuration and a .012-inch wire size, this brush delivers high-impact abrasive action suited for demanding metalworking tasks. The 5/8-inch-11 arbor mount makes it compatible with standard angle grinders commonly used in fabrication and maintenance shops. Licensed tradespeople and experienced metalworkers rely on this style of brush for aggressive stock removal and surface conditioning before and after welding operations.
This wire wheel brush is used primarily in surface preparation prior to welding, as well as for removing weld scale, spatter, and heavy corrosion from metal surfaces. It is well suited for industrial maintenance, structural steel work, pipe fabrication, and general metalworking environments where a high-impact coarse brush is required to clean or prep base metal. The coarse twist knot construction concentrates wire tips for focused cutting action on rough or heavily contaminated surfaces.

Installation Notes
Installation should be performed by qualified personnel familiar with angle grinder safety practices. Always power down and unplug or de-energize the grinder before mounting or removing the wheel. Verify that the grinder spindle speed rating meets or exceeds the maximum rated RPM of the wire wheel before operation. Wear appropriate PPE including eye protection and gloves, as wire tip breakage is a known hazard with wire wheel brushes under load.
