Tricone bits, tricone rock bit, drill bit, TCI tricone bits for hard rock drilling
Tricone Bits
Tricone rotary bits are sometimes a good alternative to a DTH hammer. Available in TCI (carbide buttons) and mill tooth configurations.
We carry a large inventory of rerun bits and can also supply new bits. TCI bits are available for Medium Soft, Medium Hard, and Hard formations. Please call us to check stock.
Remember, when drilling with Tricone Bits you need to maintain proper down pressure to prevent premature bearing failure (see chart).
Tricone roller cone drill bits maximize performance in a defined application. Our culture of continuous improvement—based on our R & D commitment to enhancing your drilling projects—achieves higher ROP with lower cost-per-foot.
We were the first company to introduce the two-cone drill bit, which was patented more than 100 years ago in 1909, launching the modern day oil and gas industry.
Twenty-four years later, we introduced the Tricone roller cone drill bit. This technology remains the industry standard with its numerous enhancements. Our product line also includes tungsten carbide insert (TCI) bits and steel tooth bits for the toughest drilling applications.
Call us or send us an e-mail to ask our experts how we can optimize your drilling program.
