The PowerGrit air chainsaw is ideal for utility, municipal, construction and industrial pipe cutting applications. Cutting ductile iron pipe is now safer, faster and easier. Available with 15- or 20-in. bar lengths, it has a cutting capacity up to 20 in. in diameter. The saw allows users to cut from one position, reducing excavation for underground pipes. Special patented diamond segments grind, rather than tear, the material, reducing vibrations and eliminating kickback for a precise, clean cut in less time.
