The CGW 60100 knot wire cup brush is a 6 inch diameter abrasive accessory designed for heavy-duty metal surface preparation. It features a 5/8-11 arbor size and a 1-3/4 inch trim, making it compatible with standard bench and angle grinders that accept this arbor pattern. The brush uses oil-drawn wire, a construction choice that enhances both durability and flexibility to help maintain aggressive cutting action while minimizing wire breakage during use. This type of knot-wire configuration is particularly effective for removing weld scale, rust, and heavy debris from flat surfaces and welded joints.
Because the brush is optimized for tough metal finishing tasks, it supports deburring and cleaning of welds or scale on various metal substrates. The 6 inch wheel diameter provides a broad contact area, enabling efficient material removal in a single pass under typical shop conditions. The brush is intended for 6600 RPM operation, which aligns with common grinder speed ranges for this class of accessory. Users should ensure their grinder’s speed rating and arbor compatibility match the 5/8-11 thread and the brush’s RPM specification to maintain safe operation and performance.
This product is supplied as a single unit, suitable for individual replacement or for when a dedicated brush is needed for frequent heavy-duty tasks in metal fabrication, maintenance, or shop floor cleanup. For best results, inspect the brush for wear and avoid using if wires become bent or deformed, and replace the brush when performance declines or signs of excessive wear appear.
