Challenger offers cold cutting machines for your pipes. The rugged and powerful CGM-1 Pipe Cold Cutting and Bevel Machine cuts and bevels pipes or shells ranging from 6 to 72 inches (152 – 1826mm) in diameter with a wall thickness of ¼” to 2 5/16” (6 – 60mm) . The CGM-1, available in pneumatic and hydraulic models, can produce almost any type of pipe end configuration imaginable including standard bevels, “J” preps and lands by simply changing the cutting and beveling blades. The machines will cut and bevel any machinable material such as carbon steel, stainless steel, ductile iron, cast iron, and most other alloys without spark or flame. A second cut is not required as the machine bevels both sides of the cut simultaneously.
