The MILWAUKEE Flexible Straight Auger is designed to be the first exploration cable head attachment to send down 2" - 2-1/2" drain lines. It is used to break up the blockage and help determine the best head to clear the clog. The steel construction and RUST GUARD plating reduce corrosion to provide 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.
