Milwaukee® drain cables with Rust Guard™ set a new standard in the market for rust protection, maneuverability and durability delivering up to 3X longer life. Traditional cables will oxidize, causing fragments of steel to erode off the cable, damaging the structural integrity. Through a proprietary plating process, Rust Guard™ plating delivers 20X more rust resistance, protecting against metal fatigue. A unique cable wind geometry provides stronger pull force and sustains shape. The smallest diameter connecting point and a solid polymer core provide the best maneuverability through the entire cable. All Milwaukee® drain cables are compatible with Milwaukee® drain machines and other professional drain cleaning machines and backed by a 2 years warranty from defect or breakage.
