✅ Fine 1.5mm Crimped Steel Wire (幼丝) provides a flexible, high-density scrubbing action that is much gentler than "Twist Knot" types, preventing deep gouging of the metal surface.
✅ 3-Inch (75mm) Diameter is the optimal size for standard 4-inch angle grinders, offering a wide cleaning path while remaining easy to maneuver in tight spaces.
✅ High-Tensile Carbon Steel construction is specifically engineered for removing light rust, old paint, scale, and surface burrs from flat or slightly curved workpieces.
✅ M10 x 1.5 Threaded Nut (standard for most Asian angle grinders) ensures a secure, vibration-free direct mount to the grinder spindle for high-speed operation.
✅ Crimped Wire Design allows for a "cushioned" contact with the workpiece, making it ideal for cleaning large surface areas where a uniform, consistent finish is required.
✅ Industrial Safety Guard—the steel cup housing protects the operator and reinforces the wire tufts, extending the life of the brush under continuous high-RPM use.
