In rock section of water well drilling application, TCI-Tungsten carbide insert tricone bits is required in drilling hard rocks. The diameter 17 1/2" is almost the biggest in water well drilling, usually small capacity drill rig can only drive 17 1/ 2" tricone drill bits to 100-150 meters depth with stabilizers for keeping well straight. With fast delivery time and warm after-sale service, China Far Eastern has serviced for mroe than 35 countries in past 10 year In drilling project, We have experience to supply the drill bits and advanced drilling soulutions for many different applications. The application including water well drilling oil field,natural gas,geological exploration,driectional boring ,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. It is also hlep us to find the siutable drill bits after you can tell us vertical well drilling or horizontal drilling ,oil well drilling. | Model | Steel tooth bit & TCI Bit |

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.
