A brand new nylon cleaning tool with a 300mm extension bar, with 6mm shaft, for the drill, for cleaning the primary heat exchangers on Baxi, Vaillant and Viessmann boilers, to name a few. This is a brilliant tool for easily cleaning the primary heat exchanger during a boiler strip service. Work smarter not harder!! For the same tool but with a more substantial 8mm shaft please check out my other listing. Thank you for looking
