The knotted wire construction delivers high-impact scrubbing action, making it well suited for removing rust, mill scale, weld spatter, and heavy coatings from ferrous surfaces. The brush measures 4 inches in diameter with a 0.014-inch wire diameter and a 1.25-inch trim length. It mounts via a 5\/8-11 threaded arbor and is rated for a maximum of 10,200 RPM. This tool is typically installed on angle grinders and used by welders, fabricators, and maintenance technicians in industrial and commercial settings.\u003c\/p\u003e\n\u003cp\u003eThe WEILER 94698 is suited for surface conditioning tasks on structural steel, pipe welds, and fabricated assemblies. Single-row knotted cup brushes of this type are commonly used in welding shops, manufacturing facilities, and field maintenance applications where a consistent, aggressive wire contact is needed prior to coating, inspection, or further fabrication. The 5\/8-11 arbor thread is a standard fit for most 4-inch to 5-inch angle grinders used in the trade.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnotted wire construction for aggressive material removal and long service life\u003c\/li\u003e\n  \u003cli\u003e4-inch brush diameter for broad surface contact on flat and curved workpieces\u003c\/li\u003e\n  \u003cli\u003e0.014-inch steel wire diameter balances cutting action with durability\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded arbor fits most standard angle grinders\u003c\/li\u003e\n  \u003cli\u003e10,200 RPM maximum speed rating for compatibility with common grinder RPM ranges\u003c\/li\u003e\n  \u003cli\u003eSingle-row design for focused, high-pressure wire contact\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with angle grinders equipped with a 5\/8-11 threaded spindle.
