The Straight Auger is designed to be the first exploration cable head attachment that is sent down the line. It will break up the blockage and help the user determine the best head to clear the clog. The steel construction gives the user longer-lasting head attachments. This head attachment works with 32mm (1-1/4") sectional cable and is designed for the MILWAUKEE® M18 FUEL™ Sectional Sewer Machine w/ ONE-KEY™.
