Weiler 94698 Knotted Cup Brush 4 in Steel Wire

Product Description

The WEILER 94698 is a knotted steel wire cup brush designed for aggressive surface preparation on metal, welds, and castings. 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.

The 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.

Compatibility

Designed for use with angle grinders equipped with a 5/8-11 threaded spindle. Verify that the grinder's no-load RPM does not exceed the 10,200 RPM maximum rating of this brush before mounting.

Installation Notes

Installation and operation should be performed by qualified personnel following applicable ANSI B11 and OSHA standards for abrasive and power brush use. Always disconnect power to the grinder before mounting or removing the brush. Ensure the spindle thread is clean and the brush is seated flush before operating. Full face shield, gloves, and appropriate PPE are required when operating wire cup brushes at speed.
