Our Flexible Straight Auger is designed to be the first exploration cable head attachment that you send down 2" - 2-1/2" drain lines. It is used to break up the blockage and help you determine the best head to clear the clog. The steel construction and RUST GUARD™ plating reduce corrosion, giving you longer-lasting head attachments. This head attachment works with MILWAUKEE® 7/8" Open Wind Sectional Cable and is designed for the Milwaukee M18 FUEL™ Sectional Machine for 5/8" and 7/8" Cable and M18 FUEL™ Sewer Sectional Machine with CABLE-DRIVE™.
