Far Eastern Drilling are API (API-7-1 & API Spec Q1) factory
specializes in drill bits, such as Tricone Bit,PDC Bit,Hybrid
Bit,HDD Hole Opener,Foundation Roller Cone Bits and related
drilling tools,application fields includes for oil well
drilling, gas well drilling, geothermal well drilling, mining,
geological survey, hydrographic survey, water well drilling, HDD
pipelines installation projects, foundation rock piling
projects. We can offer both TCI and Steel (Milled) Tooth in a
variety of sizes and all most of IADC codes in stock.According to
cutting material,tirocne bit can be divided into TCI bit and Steel
Tooth Bit .TCI is short for Tungsten Carbide Insert, tungsten
carbide is regular hard material in rock drilling field, another
material is diamond.Inserts means Tungsten Carbide teeth that's
fitting on cones of rotary drilling roller cone bits.API TCI
tricone drill bit IADC637 have type of Rubber /Elastomer sealed
bearing and Metal sealed bearing. We suggest that we had better
choose metal face sealed bearing bits for deep rock wells with hard
formations.For very deep well drilling, we recommend Metal-face
sealed bearing tricone bits in drilling depth exceeds 1000 meters,
For hard rock and long distance trenchless pilot hole drilling that
length exceeds 300 meters we also recommend metal-face sealed
bearing tricone bits.For water well drilling, shallow well drilling
or shorter distance trenchless pilot hole drilling projects,
elastomer(rubber) sealed bearing tricone bits has better cost
performance. Bit Description:IADC:637-TCI journal sealed
bearing bit with gauge protection for medium hard formation with
high compressive strength.Compressive Strength:100-150
MPA14,500-23,000PSIGround Description:Hard,well-compacted rocks
such as hard silica limestone,quarzite streaks,pyrite ores,hematite
ores,magnetite ores,chromium ores,phosphorite ores,and
