The MILWAUKEE® M18 FUEL™ SWITCH PACK™ Sectional Drum System 3/8" Kit is the first drain cleaning solution that combines the benefits of sectional and drum machines, creating the single most versatile and mobile machine on the market. The drain cleaning machine tackles the most frequent challenge of any drain cleaning application - getting the machine onto the job. The SWITCH PACK™ System utilizes a modular design with backpack straps allowing for easy transport to any roof, drain, crawl space or cleanout. The tool-free drum connection allows for quick switching between cable sizes or adding a second drum, for 100' reach down the line. All SWITCH PACK™ drain cleaning drums are fully enclosed providing the best protection against job site mess. The POWERSTATE™ Brushless Motor provides more clearing power than corded units for tough jobs in up to 4" drain lines. Built-in REDLINK PLUS™ Intelligence improves control with an integrated drum brake, slowing the machine up to 5X faster than competitor drums. Milwaukee's M18™ REDLITHIUM™ battery pack powers through multiple jobs on a single charge, providing cordless mobility, safety, and power supply to the drain cleaning industry. The 3/8" cable is best for use on 2" - 3" drain lines. The SWITCH PACK™ is also compatible with the CABLE DRIVE™ Assembly (47-53-2774) to automatically feed and retract cable up to 15-20 feet per minute. The CABLE DRIVE™ assembly quickly attaches to and swaps between any Milwaukee SWITCH PACK™ Drum with the Mounting Plate (47-53-2773) installed.
