Abstract: A chain pipe-cutter is made up of chain links joined together by cross bars, the cross bars further engage cutting wheels. A pair of adapters each having a U-shaped body with a pair of longitudinally oriented legs joined together by a back portion from which the legs depend. The legs have holes so the adapters may engaged with one of the chain links at a terminal position on the chain by cross bars. The back portions providing a groove having a longitudinal orientation so that with the chain wrapped around a brittle pipe the adapters are positioned in near adjacency, and may be further forced into convergence by a tool engaging each of the longitudinal grooves to sever the pipe.
