Iron Roughnecks Information
Iron roughnecks are tools used in the drilling industry to connect and disconnect sections of drill pipe. These machines assemble drilling pipes by clamping the lower pipe in place while a rotary wrench fastens the top pipe. The pipes mate by a series of mating threads. To replace a drill bit or upon completion of the well, the pipe is backed out of the well and the roughneck's job is completed in reverse. What was once a dangerous and dirty job for manual laborers has been replaced by this machine which is typically automated or remotely controlled.
