Expect the most work from Milwaukee® Drain Cables constructed of industrial steel spring. The solid polymer inner core delivers the best mix of strength and flexibility. It carries power through the end of the cable for maximum clog crushing force, and maneuvers the tightest bends. Milwaukee® Drain Cables won’t rust to their inner core, increasing the overall cable life. All Milwaukee® Drain Cables can be purchased with a removable inner drum to help prevent cable bind up, and reduce mess. Compatible with Milwaukee® M12™ Drain Snake and other professional drain cleaning machines, and backed by a 2-year warranty from defect or breakage.
