In 1946, Errol Glenn Gault, pioneered the first jetted rock bit. This bit patent, (#2,524,428), created a major shift in the downhole drilling industry and revolutionized the hydraulics at the bottom of the hole. This emerging technology helped pave the way for the Gault family business, to start begin operations in 1957.

What began as a small fabricating shop in Allen, OK is now a full-service rock bit manufacturing facility in Shawnee, Oklahoma that produces both TCI and Milled Tooth bits.

In 2018, GT was acquired by the oil and gas capital firm, Prestige Capital, LP. GT plans to keep the original name and strives to uphold the family legacy and standards set by the Gault family. GT looks forward to its future of providing the highest quality rock bits on the market with special service you will only find in a family business.
