Wholesale API milled tooth sealed tricone drill bits in the stock based on the lowest price and excellent quality from China supplier
Bit Description:
IADC: 117 - Steel tooth journal sealed bearing bit with gauge protection for soft formations with low compressive strength and high drillability.
Compressive Strength:
0 - 35 MPA
0 - 5,000 PSI
Ground Description:
Very soft, unstratified, poorly compacted rocks such as poorly compacted clays and sandstones, marl limestones, salts, gypsum, and hard coals.
We can offer mill tooth tricone drill bits and TCI tricone bits in a variety of sizes (from 3 7/8” to 26”) and most of IADC Codes.
According to cutting material,tirocne bit can be divided into TCI bit and Steel Tooth Bit .
Steel tooth tricone bits have another name milled tooth tricone bit since the teeth are produced by milling machine, the cone surface is hard-faced by tungsten carbide.
The steel tooth tricone bits has longer teeth than TCI tricone bits so that it can drill soft formations at high ROP.
In oil drilling projects, the ROP could reach 30 meters per hour in shallow section drilling.
When it comes to rotary drilling bits,we give you the highest performance,reliabilityand availability.Your first in choice for drilling.
Far Eastern are factory specializes in drill bits,such as tricone bits, PDC bits, HDD hole opener,Foundation roller cutters for different applications.
As a leading drill bits factory in China,increase the drill bit working life is our target. We always try to improve the bits with high penetration rates.Our mission is lower the cost of drilling-per-meter. Far eastern drilling's quality and technology will help you to achieve more!

Formation |
Very soft formations with low compressive strength and high drillability,such as clay,mudstone,chalk,etc. |
3 7/8" is always used in exploration, water well drilling and cement plug drilling, it has a central flush hole for mud fluid circulation, the bearing is sealed and thread connection is produced in rules of API 2 3/8 reg pin.
The teeth are hard-faced by tungsten carbide, teeth life is very long in drilling mudstone and soft rocks.
