Tricone Drill Bit
Tricone Drill Bit is an ideal solution from soft to hard rock formations, it is connected with the drill stem and rotates along with it, and drive cones to pressed on the rock. Each cone rotates round the axis of its leg and three cones simultaneously revolve around the bit center. The tungsten carbide inserts on the cone shell cause the formation to spall under the weight on bit and the impact load of cone rotating, the debris will be discharged out to hole by compression air.
Hope tricone bit used for geoloical prospecting, development of oil and gas,drilling water wells, blast holes and making holes for seismic prospecting, construction engineering. Now there are eleven common types of tricone rock bits.
Steel teeth series: IADC CODE: 116, 117, 126, 127, 136, 137, 216, 217, 317, 337.
TCI series: IADC CODE: 417, 437, 447, 517, 527, 537, 547, 617, 627, 637, 647, 737, 837.

FAQ
Q1. What formations are PDC water well drill bits suitable for?
A: Our PDC bits are ideal for drilling in soft to medium-hard formations, such as clay, sandstone, shale, and limestone. For harder formations, we recommend consulting us for customized cutter designs.
Q2. Can you customize the drill bit size and connection type?
A: Yes. We offer a wide range of sizes (3"–17") and thread connections (API REG, API IF, etc.). Custom specifications are available based on your drilling rig and project requirements.
Q3. How long is the service life of your PDC bits?
A: Service life varies depending on formation hardness, operating parameters, and maintenance, but our PDC bits typically last 2–4 times longer than traditional steel tooth or tricone bits under similar conditions.
Q4: Do you offer OEM or branding services?
A: Yes, we support OEM/ODM services, including logo engraving, packaging design, and custom color options.
Q5: How long is your delivery time?
A: For customized sizes, delivery is typically within 7–15 working days depending on order quantity and complexity.
Q6: Can I get a sample to test quality?
A: Yes, sample orders are welcomed. We suggest starting with a trial quantity to verify performance in your local drilling conditions.
