A machine that integrates the function of a spinning wrench and a torque wrench to make up and break out drill pipe connections. These machines evolved to replace manual connections and increase the safety of making and breaking connections by eliminating the manual handling involved with suspended individual tools. The machine may be configured as a single wire hung device or as an arm-deployed or floor rail-mounted device to facilitate the continual hydraulic movement of the machine in and out from a well center, mousehole, and in some cases the rathole location. Some larger machines incorporate pipe thread doping and cleaning systems, bit breakers, mud buckets and full remote control and/or automated operations. Some machines adapt to connect casing tong mechanisms and some cover a full range of tubular and casing up to 20 ft.
