Brawny Rock Bits

1)Bits size range :3-3/5"-26"
2)Best quality and low price
3)Longer drilling intervals
4) API &IADC

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 Structure	The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
Bearing Structure	Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the cone which reduces the probability of cone Cdropping to minimum.
Main Type Available	Size: 2 3/8",3",3 5/8:",3 7/8",4",4 1/2",4 5/8",4 3/4",6",6 1/2",7 1/2",8 1/2",9 1/2",9 5/8",9 7/8",12 1/4",15",15 1/2",17 1/2", etc. IADC Code:5-- Series,6-- Series

HJT437

437

It 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.

0.35~0.90

280~60

HJT447G

447

It 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.

HJT517J

517

It 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
