✅ High-tensile Twisted Steel wire construction provides an aggressive internal scrubbing action for removing heavy rust, scale, and carbon buildup from pipes and bores.
✅ Double-Spiral "Bottle Brush" design is specifically engineered for internal cleaning, deburring cross-holes, and polishing cylindrical workpieces.
✅ Integrated Loop or Straight Shank options allow for manual hand scrubbing or easy mounting onto power drills and extension rods for deep-reach cleaning.
✅ Industrial-grade Carbon Steel bristles maintain their stiffness and shape even under high rotational speeds, ensuring a uniform finish inside tubes.
✅ Flexible Steel core allows the brush to navigate slight bends and irregular internal surfaces without getting stuck or losing cleaning power.
✅ Wide range of diameters (from 6mm to 200mm) ensures a perfect fit for everything from small engine fuel lines to large industrial flue pipes and boilers.
