Product Description
Far Eastern Drilling are API (API-7-1 & API Spec Q1) factory specializes in drill bits, such as Tricone Bit,PDC Bit,Hybrid Bit,HDD Hole Opener,Foundation Roller Cone Bits and related drilling tools,application fields includes for oil well drilling, gas well drilling, geothermal well drilling, mining, geological survey, hydrographic survey, water well drilling, HDD pipelines installation projects, foundation rock piling projects. We can offer both TCI and Steel (Milled) Tooth in a variety of sizes and all most of IADC codes in stock.
The cutting teeth of hard - rock well tricone bits are key components for effective drilling in hard - rock formations.
The cutting teeth of hard - rock tricone bits often use tungsten carbide - based cemented carbide materials. This material has extremely high hardness, with its hardness value usually ranging from HRA85 - 92 on the Rockwell hardness scale, second only to diamond. High hardness enables it to resist the wear of cutting teeth by hard rock and maintain the integrity of the tooth shape during the drilling process.
At the same time, cemented carbide also has good compressive strength and can withstand the huge axial pressure during drilling without plastic deformation. Its compressive strength can reach several GPa. For example, the compressive strength of some high - quality cemented carbide cutting teeth can reach 4 - 5GPa.
Coating Enhancement
To further improve the performance of the cutting teeth, some cutting teeth surfaces are coated with a special coating. Common coating materials include titanium nitride (TiN), titanium carbide (TiC), etc.
The thickness of these coatings is usually between a few micrometers and several tens of micrometers. For example, the thickness of the TiN coating is generally 2 - 5μm. The coating can improve the wear resistance, corrosion resistance, and lubricity of the cutting teeth. When the coated cutting teeth are used in hard - rock drilling, they can reduce the friction coefficient with the rock, decrease the wear rate of the cutting teeth, and improve the drilling efficiency of the bit.

Incoterm: FOB or CIF or CFR, by plane or ship, port of destination/discharge.
The more information provided, the more exact quotation will be offered.
2. What is the quality control for your products?
Answer: All of our production are in lines of API rules and ISO9001:2015 strictly, from signing contract , to raw materials, to each production processes, to product finish, to after-sale service, each processes and sections are in accordant with standard.
3. About lead time,payment terms, delivery ?
Answer: We always have regular models available in stock, prompt delivery is one of our advantages. Mass production depends on quantity of order.
We accept all regular payment terms including L/C, T/T, etc.
We are near from Beijing airport and Tianjin(Xingang) seaport, transportation from our factory to Beijing or Tianjin only takes one day, fast and very economical inland charges.
4. What is the history of Far Eastern ?
Answer: The drilling bits business was started at year 2003 only for China domestic requirement, the name Far Eastern was started from year 2009, now Far Eastern has exported to more than 35 countries and areas.
5. Do you have Referenced Letters /Recommendation Letters from old customers?
Answer: Yes, we have many referenced letters/recommendation letters issued by old customers who would like to share our stories.
