Product Description
Far Eastern Drilling are API (API-7-1 & API Spec Q1) factory specializes in drill bits, such as PDC Bit,Tricone 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.
Polycrystalline diamond compact (PDC) bits deliver premium performance and durability for a wide range of standard drilling applications. According to body material,PDC bit can be divided into Steel body and Matrix body.These matrix- and steel-bodied bits incorporate the latest cutter technology, computational fluid dynamics (CFD), enhanced hydraulics, and various structure geometries to maximize ROP.
Matrix-body PDC bits are commonly preferred over steel-body bits for environments in which body erosion is likely to cause a bit to fail. For diamond-impregnated bits, only matrix-body construction can be used.
Matrix body PDC bits are primarily used for these applications:
Steel body PDC bits are primarily used for these applications:
Different from tricone bits, the PDC drill bits need lower WOB but higher RPM,so it always works with mud motor to get high rotating speed.
Quality of PDC drill bits mainly depends on quality of PDC cutters,we provide unique solution according to specific requirement and detailed geological information.









FAQ
1. How to get an exact quotation?
Answer: Please send us detailed information as below:
-Tricone bits(Diameter, IADC code)
-PDC bits(Matrix or Steel body, blades quantity, cutter size, etc)
-Hole opener(Diameter, size of pilot hole, hardness of rocks, thread connection of your drill pipe, etc.)
-Roller cutters(Diameter of cones, model number, etc.)
-Core barrel(Diameter, quantity of cutters, connection, etc.)
A simple way is sending us photos .
Besides above, if possible please provide more information as below:
Drilling depth in vertical well drilling, Drilling length in HDD, hardness of rocks, Capacity of drill rigs, application(oil/gas well drilling, or water well drilling, or HDD, or foundation).
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.

Matrix-body PDC bits are commonly preferred over steel-body bits for environments in which body erosion is likely to cause a bit to fail. For diamond-impregnated bits, only matrix-body construction can be used.
Matrix body PDC bits are primarily used for these applications:
- Soft to medium-hard formations
- High volume
- High sand
- Applications where the same bit will need to be used for several bit runs
Steel body PDC bits are primarily used for these applications:
- Drilling in shale formations
- Soft limestone sites
- Fast drilling in the stratum
- Natural gas drilling
- Deep wells
- Abrasive formations
Different from tricone bits, the PDC drill bits need lower WOB but higher RPM,so it always works with mud motor to get high rotating speed.
Quality of PDC drill bits mainly depends on quality of PDC cutters,we provide unique solution according to specific requirement and detailed geological information.
