2022 High quality Api Tci Bit - API three cones bit IADC537 11 5/8″(295mm) for hard well – FAR EASTERN

Product Description

It is important for the quality of drilling bits during the job.We do our best to improve the bit .
1)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.
2)Metal sealed journal bearing extend cuttter
The bit can achieve longer service life and higher reliability.
3)Body and Welding
The steel body with high strength after heat treatment.
The three legs welded together with quality electrodes to ensure stability in structure.To further enhance the stability ,the bits go through heat treatment to relieve stresses after welding.

Product Specification

11 5/8″ is 295 mm in diameter, the thread connection is 6 5/8 reg pin according to API specification.
11 5/8″ is a popular diameter in Middle Asian and Eastern Euorpe oil well drilling fields, the countries includes Kazakhstan, Uzbekistan, Turkmenistan, Ukraine, Russia, it is rarely used in USA, South Africa and South-East Asia.
Both steel tooth tricone bits and TCI tricone bits are available for 11 5/8″, we have adequate stock for 11 5/8″ IADC127, 137, 217, 517, 537, they are regular models requested by drillers.
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, 10 5/8″(269mm) 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 suitable tricone roller bits.
