ABSTRACT:
An apparatus that can be used during drilling operations for the purposes of clamping and holding drilling tubulars is disclosed. The embodiments relate to machinery that clamp and hold drilling tubulars to allow assembly to a specified torque or disassembly of the tubulars. The apparatus comprises a first grip with teeth inserts housed in a gripping block that opposes a second grip with teeth inserts housed in a second gripping block. The first and second grips are spaced and adapted to accommodate a range of diameters of drilling tubulars. Further, the gripping blocks are held by opposing arms connected to a driving means to create a tightening or loosening movement of the grips and maintain a certain orientation with regard to the tubulars.
