Key benefits Durable materials: Manganese steel and spring steel wire provide good deformability, strength, and rust resistance after treatment. Flexible and bendable: spring design allows easy passage through curved pipes, quickly reaches dead corners, and removes hidden debris. Broad compatibility: universal drill interface fits ordinary electric drilling machines. Material and construction Material: Manganese steel material and spring steel wire Deformability: good, not easy to break Corrosion resistance: rust protection after treatment Design and performance Bendable spring design enables smooth navigation through curved pipes Efficiently dredges dead corners and extracts hidden garbage from pipes Compatibility Universal drill interface suitable for ordinary electric drills Use scenarios Home plumbing maintenance: clear curved drain pipes under sinks, removing hair and buildup Small machinery maintenance: clean curved tubing and channels in compact equipment DIY projects: use with a drill to reach tight bends in pipes or channels for cleaning and debris removal
