The Micro Premium lateral cutter from Pipeline Renewal Technologies delivers 30 percent more cutting power than the smaller Micro Pro, as well as a touch-screen interface, large reservoir for flushing water and easy connection/monitoring of supply air. Using remote-inflated air bladders, the arm of the unit positions itself remotely by creeping and climbing, clamps itself for precise cutting in vertical or horizontal orientation and feeds the cutting head a full 4 inches. Just 72 mm in diameter, the arm fits through small openings, and its agile articulation (400-degree rotation and 90-degree swivel) facilitates precision cutting, as well as maneuvering through 90-degree bends in 4-inch lines. 866/936-8476; www.pipelinert.com.
