✅ High-tensile Carbon Steel bristles provide a maximum-aggression scrubbing action, perfect for tearing through heavy rust, scale, and thick layers of old paint.
✅ Ergonomic curved "Toothbrush" or "Block" handle (available in durable plastic or wood) is designed for a firm, non-slip grip to handle high manual pressure.
✅ Industrial-grade 4-Row or 3-Row density ensures a wide cleaning path, significantly reducing the time and effort required to clean large metal surfaces.
✅ Heat-treated wire construction maintains bristle stiffness and prevents bending or flattening even when used on extremely rough or jagged workpieces.
✅ Heavy-duty application range is ideal for cleaning cast iron, structural steel beams, dirty engine blocks, and prepping heavy machinery for repainting.
✅ Secure staple-set technology locks each wire tuft deep into the handle, preventing bristle shedding and ensuring a long tool life under harsh workshop conditions.
