What this is A 10-piece set of stainless steel replacement blades for copper pipe cleaners, designed to attach to a drill for fast, consistent cleaning of 15 mm and 22 mm copper pipes. Key benefits — why you need it Durable, corrosion-resistant blades: made from stainless steel to resist rust and wear, giving longer life and consistent performance over repeated use. Saves time and effort: drill-mounted operation rapidly removes debris and buildup inside pipes, shortening cleaning and repair jobs. Cost-effective replacement: an affordable, reliable set that helps you maintain installation tools and systems without frequent costly blade changes. Main features Material: stainless steel blades that resist corrosion and abrasion. Sizes: includes blades for both 15 mm and 22 mm copper pipe diameters to cover common plumbing needs. Function: engineered for efficient removal of scale, solder residues, oxidation and other internal debris. Compatibility: designed to be used with a drill (attach to your drill for rotary cleaning); provides consistent results when properly mounted. Pack size: 10 blades in total, offering spare parts for multiple jobs or ongoing maintenance. Typical applications Pre-solder preparation: quickly clean the inside of 15 mm and 22 mm copper pipes before soldering or brazing to improve joint quality. Routine maintenance: remove mineral deposits and buildup from domestic water or heating lines during service calls. HVAC and refrigeration work: clear debris from copper lines during repairs or line replacements to restore flow and prevent blockages. Practical notes Use at appropriate drill speeds and with steady pressure to avoid damaging the pipe or blade. Inspect blades regularly and replace when worn to maintain cleaning efficiency. The set provides a simple, reliable option for plumbers, HVAC technicians, and DIYers who need a fast, repeatable way to clean 15 mm and 22 mm copper pipes.
