Abstract: A Toggled Breakout Wrench is described for use with a drilling rig having a drill stem made up of one or more drill pipe sections. The wrench comprises an arm movably connected to the drilling rig such that the arm will move in a substantially arctuate path about a drill pipe section. Pivotally mounted to the arm are a pair of opposed jaws for clamping about the drill pipe section to assist in breaking loose the threaded connections of the drill pipe sections. A toggle linkage enables the opposed jaws to move between a clamping and a non-clamping position about the drill pipe section.
