CGW 60091 is a knot-style wire cup brush designed for heavy-duty metal surface preparation. With a 3-1/2 inch diameter and a 5/8-11 arbor, this brush integrates a .020 inch wire knot pattern to balance aggressive material removal with durability. The 1-3/8 inch trim length positions the wire close to the work surface, enabling efficient cleaning, deburring, and rust or weld-scale elimination on flat surfaces and irregular welds alike. Operated at up to 12,500 RPM, the brush is intended for use on metal workpieces where controlled material removal is required without excessive gouging.
Constructed from oil-drawn wire, the brush emphasizes flexibility and break resistance under demanding shop conditions. The knot-wire configuration provides multiple contact points that help lift and remove surface contaminants, making it suitable for surface prep prior to finishing or coating applications. When selecting this brush, consider the balance between aggressiveness and control, as well as the rotational speed and the workpiece material to avoid excessive heat buildup or wire contact. Proper mounting to a compatible tool with an appropriate arbor is essential for safe operation.
This product ships as a single unit, with a 5/8-11 arbor size compatible with common right-angle and die grinders that support that threading. Maintain and inspect the brush regularly for wire wear or deformation, and replace after signs of fatigue to preserve performance. The specification details provided reflect the manufacturing design: 3-1/2 inch diameter, .020 inch wire, 1-3/8 inch trim, and 12,500 RPM capability, which guide selection for applications such as scale removal, rust cleaning, and weld seam prep.
