12 1/4" TCI Tricone Bits
As one of the most commonly used oilfield drill bits, our tricone bit is a primary tool used for drilling, and is widely used for oil and gas exploitation.
Additionally, our tricone drill bit can also be used for drilling water wells, blast holes, making holes for seismic prospecting, and used in construction engineering.
We keep a generous inventory on hand ranging from 3-7/8" through 26" and can provide larger sizes on request. These bits are typically sealed bearing. All come with regular API connections. These bits feature 3 or 4 jet ports, the 4th being an optional center jet. We house all jet sizes to meet your TFA (Total Flow Area) requirements. We offer both standard high quality and premium quality re-run as well as NEW and SURPLUS NEW Tricone bits.
