TCI Tricone Bits 415
Soft Formation TCI Tricone Bits
1)The 415 tci bits are used to drill low compressive strength, very soft formations.

2)TCI bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection.

3)This cutting structure design, combined with maximum cone offset, results in high bit penetration rates.

4)The deep intermesh of cutter rows prevents bit balling in sticky formations .

TCI Tricone Bits 535
Medium Formation TCI Tricone Bits
1)The 535 features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. 2)This design provides a fast drilling rate and added cutting structure durability in medium-to-medium hard formations.

3)The HSN rubber O-ring provides adequate sealing for bearing durability.

Non-Sealed Roller Bearing Bit
Cutting StructureThe durability of premium tungsten carbide inserts is

improved with new formulas and new techniques for insert bit.

Bearing StructureNon-sealed roller bearing. Drilling fluid can enter the bearing

directly for cooling; Balls lock the cone which reduces th

e probability of cone Cdropping to minimum.

HJT437It is used for low compressive

strength and exceeding soft formation

of high drillability, such as, shale, clay,

sandstone, soft limestone, halite, gypsum etc

Its structure is Large-diameter side

top row of teeth within the spoon-shaped,

and wedge-shaped outer row of teeth. Its teeth

are different height and the margin is not

different distance, also it increases

a row of trimming teeth between the

back conical teeth and outer row of teeth.

0.35~0.90280~60
HJT447GIt is used for low compressive

strength and exceeding soft formation

of high drillability, such as, shale,

clay, sandstone, soft limestone, halite, gypsum etc

Its structure is Large-diameter

side top row of teeth within

the spoon-shaped, and wedge-shaped

outer row of teeth. Its

teeth are different height and the

margin is not different distance,

also it increases a row of trimming

teeth between the back conical teeth

and outer row of teeth.

0.35~1.00240~60
HJT517JIt is used for low compressive

strength and soft formation of high

drillability, such as, shale, clay,

sandstone, soft limestone, halite, gypsum etc

Its structure is Large-diameter

side top row of teeth within the

spoon-shaped, and wedge-shaped

outer row of teeth.

Its teeth are different height and the

margin is not different distance, also

it increases a row of trimming teeth between

the back conical teeth and outer row of teeth.
