The RIDGID K-6200 Drum Machine cleans 3- to 6-inch drainlines up to 200 feet and offers a compact design for easy access to tight work areas. It comes with either inner-core cable for greater flexibility or integral-wound cable for enhanced durability, as well as a cable control system that causes the drum to slow down when the blade becomes lodged in a blockage. This limits the potential for cable flip over in the drum. It incorporates direct-drive design with a powerful 2/5 hp universal motor and gearbox that bears down as torque builds, providing the necessary strength to cut through roots, hardened grease and other tough blockages. In addition, an audible warning signals when a blockage has been encountered. The drum stays aligned without the need to make adjustments, limiting work interruptions. 800-769-7743; www.ridgid.com.
