  New Steel Tooth Tricones  Milled Tooth bits are available for all formations, and in all sizes. Tooth spacing and length vary depending on application.   NEW TCI Sealed Journal Bearing Tricones Floating bushings provide excellent durability and wear resistance. The bushing is made out of special mate- rial that is highly resistant to heat and surface damage. TCI bits maximize the use of both conical and chisel tungsten carbide inserts, for soft to hard formations.

Tungsten Carbide Tricone Rock Bits IADC CODE--- Formation

IADC 437  Soft Formation     The 437 tci bits are used to drill low compressive strength,very soft formations .TCI bits maximize the use of bothconical and chisel tungsten carbide inserts of large diameters and high projection.This cutting sstructure design,combined with maximum cone offset,results in high bit penetration rates .The deep intermesh of cutter rows prevents bit bailing in sticky formations.

IADC 517   Medium Formation     The 517features aggressive chisel tungsten carbide inserts on the heel rows and inner rows.This desing provides a fast drilling rate and added cutting structure durability in medium-to medium hard formations .The HSN rubber o-ring provides adequate sealing for bearing durability.

IADC 617  Medium-Hard Formation     The 617features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows.This design provides a fast drilling rate and added sutti8ng structure durability in medium to medium hard formations .The HSN rubber o-ring [rovodes adequate sea;omg fpr bearomg dirability.

IADC 637  Hard Formation     The 637bits can be used to drill hard and abrasive formations .Wearresistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge.Maximum numbers of bemisphericalshaped inserts are used in all rows to provide cutter durability and long life.

    Shown :   Sealed Bearing Tricone Drilling Bits   ----Cutting Structure  Steel Tooth: Premium tungsten carbide hard facing on the surface, it’s greatly enhance the wear resistance of the tooth. Tungsten Carbide Inserts: Various type high quality tungsten carbide inserts can be equipped on the bits, professional and scientific selection of the inserts as per the different application and drilling process so that to achieve high efficient drilling production. ----Gauge Structure  Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life. ----Bearing Structure  Journal bearing and roller bearing types are available to be chosen. Abrasion & seizure resistance, loading capacity, stability of the bearing are well improved, suitable for high speed rotary drilling. ----Seals and Lubrication  The advanced metal seals improve the reliability and stability of the bearing sealing. Pressure difference type compensating system assures a good greasing lubrication function.         The Advantages to Use Tricone BitsThan Other Kinds of Rock Bits   There is a tricone suitable for any rock formation Tricone bits are versatile and can handle changing formations Tri cones Are reasonably priced with long life and good rate of drilling         Siruite Company Info:             Urumqi siruite rock drilling tools company is located in Urumqi city,and branch-office in Hejian city of Hebei province.
