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.
Choose the proper rocks drilling bits is very important before starting project. For very deep well drilling, we recommend Metal-face sealed bearing tricone bits in drilling depth exceeds 1000 meters, for hard rock and long distancetrenchless pilot hole drilling that length exceeds 300 meters we also recommend metal-face sealed bearing tricone bits. Rocks hardness could be soft, medium and hard or very hard, hardness of one type of rocks may be also a little different, for example, limestone, sandstone, shale has soft limestone, medium limestone and hard limestone, medium sandstone and hard sandstone, etc. In drilling project, Far Eastern have 15 years and more than 30 countries services experience to supply the drill bits and advanced drilling soulutions for many different applications. The application including oil field,natural gas,geological exploration,driectional boring,water well drilling ,The various drill bits can be customized as per different rock formation becasue we have our own API & ISO certified factory of tricone drill bits. We can give our engineer's solution when you can supply specific conditions, such as hardness of rocks,types of drilling rig,rotary speed,weight on bit and torque.
