API triocne drilling IADC125 17 1/2 inches (444.5mm)
Product Description
Wholesale API tricone bits for well drilling in the stock based on the lowest price and excellent quality from China factory
Bit Description:
IADC: 125 - Steel tooth journal sealed bearing bit 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 and TCI tricone drill bits in a variety of sizes (from 3 7/8” to 26”) and most of IADC Codes.
Milled teeth tricone bit is used for drilling soft formations, the advantage is higher ROP(Rate of Penetration) than TCI tricone bit, it has faster drilling down speed than Tungsten Carbide Insert tricone bit in drilling mudstone or other sticky rocks.
TCI tricone bit is suitable for drilling hard rocks, but bit-balling always happens in drilling soft and sticky formations which prevents drill bit going down.
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 you choose a FAR EASTERN drill bit, you get the right bit for the right application, so you can stay in the hole longer with fewer trips, at a lower cost-per-foot. Because we’ve been engineering this technology successfully for more than 15 years, we are confident in our legacy and that no other drill bit manufacturer can match our expertise.
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 purpose is to sell the high quality with the lowest price. Far eastern drilling quality and technology will help you to achieve more!
Product Specification
Steel tooth tricone bits are also named milled tooth tricone bit, "steel" means the teeth material is steel, actually it is a type of special steels 15MnNi4Mo and the surface of steel material is hard faced by Tungsten Carbide to increase wear resistance
Milled means the teeth is machined by milling machine, so steel tooth tricone bits have another names "mill tooth tricone bits" or "milled tooth tricone bits".
26 inches is always diameter of the first hole in deep well drilling, the formations are always soft in shallow section, so 26" is widely used in worldwide
Choose the correect and suitable IADC code to reach the best cost-effective, we are pleasant to choose the right tricone bits according to your geological information.
Far Eastern Drilling attends exhibitions in many countries worldwide, hopefully to talk with you face to face in near future.
