Product Description

Wholesale API oil tricone rock drill bits in stock with discounted price from China factory
Far Eastern Drilling can offer TCI tricone bits and steel teeth tricone bits in a variety of sizes (from 3” to 26”) and most of IADC Codes.
IADC: 237 is Steel tooth journal sealed bearing bit with gauge protection for medium to medium hard formations with high compressive strength.The compressive strength is 20-40MPA and 3000-6000PSI/20 - 40 MPA/3,000 - 6,000 PSI.
IADC237 triocne bits will be used for sandstones with streaks of quartz, hard limestone or chert, crystalline dolomites, hematite ores, and hard shales.

Find the siutable rock drilling bits is the first step befor drilling project.
We will share some details about how to choose right tricone bits?
A.There are 2 types of triocne bits based on teeth type.
1) Steel ttooth tricone bits (IADC1**,IADC2**,IADC3**)
2) TCI tricone bits (IADC4**,IADC5**,IADC6**,IADC7**,IADC8**)
B.There are 4 types of tricone bits based on bearing type.
1) Journal bearing (IADC**6,IADC**7)
2) Roller bearing (IADC**4,IADC**5)
3) Open bearing (IADC**1)
4) Air bearing (IADC**2,IADC**3)
C Some details:
1) Soft formation better choose steel tricone bit,e.g mud.
2) Hard formation better choose TCI tricone bit,e.g limestone.
3) Roller bearing, journal bearing are mostly used in water well drilling projects.
4) Open bearings, air bearing, roller bearing are mostly used in mining projects.
5) Chosse the tricone bit as per compressive strength

PSI	IADC code	Formation
0~4000	IADC1**	clays and sandstones, salts
4000~8000	IADC2**	marl limestones，gypsum, and hard coals.
8000~15000	IADC3**	sandstones with quartz binder, hard sandstones, hard quartz shales, magma, and metamorphic rocks.
15000~25000	IADC4**	shales, dolomites, sandstones, clays, salts, and limestones.
25000~40000	IADC5, IADC6	sandstones with quartz binder, dolomites, quartzite shales, magma and metamorphic coarse-grained rocks
More than 40000	IADC7, IADC8	hard silica limestones, quartzite streaks, pyrite ores, hematite ores, magnetite ores, chromium ores, phosphorite ores, and granites
