CS Unitec’s PowerGrit Air Chain Saw cuts pipe measuring up to 20 in. in diameter, including ductile iron, cast iron, PVC, HDPE and cured-in-place piping. Ideal for utility, municipal, construction and industrial pipe cutting applications, the user can cut pipe from one position, reducing underground excavation. Pneumatic power eliminates exhaust fumes, making it suitable for use in confined spaces. Diamond segments grind rather than tear the material, reducing vibration. Fifteen- and 20-in. bar lengths are available.
