The CGW 60104 Knot Wire Cup Brush is a 4-inch diameter wheel designed for metal surface preparation, including cleaning welds, removing rust and scale, and deburring flat surfaces. It features a 5/8-11 arbor and a trim length of 1-3/4 inches, making it compatible with standard bench and angle grinders that accept these arbor sizes. The brush uses oil-drawn wire, which enhances durability and flexibility for repeated use in heavy-duty cleaning and deburring tasks common in fabrication, maintenance, and repair workflows.
Constructed with carbon steel knot wire, the brush is intended for aggressive metal finishing applications where weld scales, rust, and burrs must be removed efficiently. The knot configuration provides a balance of aggressive material removal and surface finish, helping to prepare parts for welding, painting, or coating by producing cleaner, smoother base surfaces. Operators should observe proper grinding practices and PPE, including eye and face protection, as the brush operates at high RPMs to remove_scale and contaminants.
In terms of compatibility and use, this brush is sized for a 4" wheel with a 5/8"-11 threaded arbor and is specified for use up to 6600 RPM. It ships as a single unit and is intended for professional maintenance and fabrication environments where reliable, consistent wire contact is needed for heavy-duty cleaning and deburring tasks. When selecting, verify your grinder’s arbor compatibility and operating speed to ensure safe, effective use with this knot wire cup brush.
