A History of
Delivering Results

Our company has a long robust history that began when a pioneer in the oil field by the name of Marvin Gearhart founded Rock Bit Industries in January 1976. Since then, our company’s name has changed several times, but we have maintained our founders spirit, quality, and innovative thinking. Over the years, we have been purchased by investors and other companies each with their own strengths, character, and history. We have remained a Fort Worth, Texas based company while we continue to manufacture Roller Cone and PDC Bits for the North American market.
