Hughes Christensen, is one of the worlds largest oil and gas drilling and evaluation service companies primarily responsible for the production of drill bits. It was formed from the merger of Hughes Tool Company and Christensen Diamond Products. In 1987, Baker International acquired and merged with Hughes Tool Company to form Baker Hughes Incorporated. Shortly after in 1992 Baker Hughes acquired Christensen Diamond Products and merged it with Hughes Tool Company to form the drilling and evaluation division, Hughes Christensen.

After the merger, Hughes Christensen introduced the AR Series, the newest antiwhirl technology capable of penetrating a much wider variety of tough formations without the catastrophic cutter fracture experienced by conventional PDC bits. AR Series bits were designed to resist bit whirl by directing load forces through low-friction gauge pads. By 1995, Hughes Christensen's Gold Series PDC line increased drilling efficiency by reducing the frictional forces that can accumulate in front of the cutting edge, reducing the energy required to remove the rock. A year later patented ChipMaster PDCs, known for their efficiency and durability, were built on the success of the Eggbeater product line. Hughes Christensen next introduced the Genesis HCM bits for steerable motors with patented EZSteer depth-of-cut control technology. This same technology was adapted to Genesis HCR bits for rotary steerable systems, such as the Baker Hughes AutoTrak rotary closed loop system. Genesis ZX PDCs followed with new Zenith cutters.
