2022 High quality Api Tci Bit - API TCI button bit IADC537 9 7/8″(250mm) for hard rock well drilling – FAR EASTERN
2022 High quality Api Tci Bit - API TCI button bit IADC537 9 7/8″(250mm) for hard rock well drilling – FAR EASTERN Detail:
Product Description
Tender of API TCI drilling bits in the stock from China factory
We try our best to improve the quality of drill bits.
1)Gauge Protection
Special inserts are strategically arranged on head to effectively reduce head wear in abrasive formation and directional and horizontal wells and extend bit life.
2)Cooling system
The nozzles is very important part in the life of a bit, bit hydraulics are controlled through these nozzles,it is also heat treatment for more strength and stability.
3)Extremely high quality tungsten carbide
High effectively cutting ability and strong anti-breaking ability, which can increase ROP and improve service life of bit effectively

9 7/8″ is 250mm in diameter, the thread connection is 6 5/8 reg pin according to API specification.
IADC537 means that tricone roller bit is suitable for drilling medium hardness rocks like limestone, shale, gypsum, etc. The bearing is elastomer sealed to increase working life.
Tungsten carbide inserts(TCI) is very hard alloy to drilling hard rocks, the heel of cones and arm-back are full inserted with Tungsten Carbide teeth.
It is a common size in mining field, to drill blast hole. In mining drilling, first number for IADC code are usually 6,7,8,and the third number are usually 2 and 5.
According to IADC specifications for tricone bit,”2″ means standard open bearing roller bit,and “5″ means sealed roller bearing bit with gauge protection.
In some countries, 9 7/8″(250.8mm) is often used to drill water well and geothermal well. Drill rig is circulated by mud fluid,instead of compressing air.
Therefore, for different applications, we should choose the right tricone roller bits.
