Weiler 94660 Knotted Wheel Brush 5 Inch Carbon Steel

Product Description

The WEILER 94660 is a knotted wire wheel brush designed for aggressive surface preparation and weld cleaning on metal workpieces. It mounts via a 5/8-11 threaded arbor and runs at a maximum of 12,500 RPM, making it compatible with standard angle grinders and bench grinders used in fabrication, maintenance, and industrial cleaning work. The brush uses stringer bead twist knotted carbon steel wire in the 0.0200 to 0.0299 inch diameter range, delivering the concentrated cutting action that knotted wire is known for on heavy mill scale, rust, and weld spatter. Welders, pipefitters, and metalworkers are the primary installers and users of this tool.

This wheel brush is suited for use in industrial, commercial, and job-site environments where thorough deburring, descaling, and surface conditioning are required before welding, coating, or inspection. Its 5-inch outside diameter and 3/16 inch face width make it well matched to standard 5/8-11 threaded right-angle grinders. The 7/8 inch trim length and stringer bead twist knot pattern concentrate wire pressure for consistent stock removal on steel and iron surfaces.

Installation Notes

Installation and operation should be performed by qualified tradespeople familiar with abrasive wheel safety. Always power down and disconnect the grinder from its power source before mounting or removing the brush. Verify the tool spindle speed does not exceed the 12,500 RPM maximum rating marked on the brush before operating. Operators should wear appropriate PPE including eye and face protection, and ensure the work area is clear of bystanders, as wire bristles can break free during use.
