Our 1-1/4" Opening Tool is designed to penetrate hard blockages and get water flowing. This drain opening tool is best used in 1-1/4" to 2" pipes. The steel construction and RUST GUARD™ plating reduce corrosion, providing you with longer-lasting head attachments. This head attachment works with MILWAUKEE® 5/8" x 7.5' Open Wind Sectional Cable designed for the Milwaukee M18 FUEL™ Sectional Machine for 5/8" and 7/8" Cable.
