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.

Steel Tooth Tricone Rock Bits

IADC CODE---Formation

IADC 114. 115.116.117 Soft formation

The 114-117 bits are used to drill low-compressive strength,soft formations. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hard facing is used to control tooth wear.On the softest bi types this hard facing completely covers the bit teeth

IADC Medium formation

Medium formation with high-compressive strength and high drillability. Such as sandstone, anhydrite, salt, shale, limestone.

IADC Medium soft formation

Formations with low compressive strength, such as shale, anhydrite, sand and so on for soft formation

IADC216.217 Medium hard formation

The 216-217 bit are always used to Soft to medium formations with

low-compressive strength, such as shale, anhydrite, sand and so on for soft formation.
