Wholesale API rotary steel tooth tricone drilling bit in stock based on the lowest price and excellent quality from China factory
Bit Description:
IADC: 217 - Steel tooth sealed roller bearing bit with gauge protection for medium to medium hard formations with high compressive strength.
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.
Far Eastern Drilling can offer mill tooth and TCI tricone drill bits in a variety of sizes (from 3 ” to 26”) and most of IADC Codes.
According to cutting material,three cones bit can be divided into TCI bit and Steel Tooth Bit
Steel tooth tricone bits have another name milled tooth tricone bit since the teeth are produced by milling machine, the cone surface is hard-faced by tungsten carbide.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.
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,mining ,water well drilling ,HDD, construction,and foundation.The various drill bits can be customized as per different rock formation becasue we have our own API & ISO certified factory of 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 or No-Dig drilling or foundation piling.

Dense teeth on cones of tricone bits means smaller teeth and harder rocks drilling capacity, shorter and smaller teeth makes milled teeth tricone drill bit can even drill soft or medium hardness rocks and the ROP is higher than TCI tricone bits. Surface of cones are enhanced by tungsten carbide hard-facing.
