Tricone Bit
K-Cuttering Structure for hard plastic formation
K-Cuttering Structure for hard plastic formationUnique designing parameters and lengthening insert crest enlarge rock-breaking volume at the bottom hole and increase bottom hole coverage and increase ROP of the bit in hard plastic formation.
Y- Conical-spherical inserts
If bit is equipped with conical-spherical inserts as main cutting elements, then the bit is suitable for drilling in hard and brittle formations.
Nozzles
Nozzles can effectively avoid the bit balling, eliminate the bottom of the fluid retention area, speed up the cuttings upwards, and improve the bit penetration rate. It is suitable for soft to medium-soft formation with low compressive strength and high drillability.
T- Trimming Cutter
T- Trimming CutterA row of teeth is added between the back bevel teeth and the outer row of teeth, which have double actions of trimming sidewall and protecting the cone body.
G-Gauge Protection
Strengthening of bit dorsal metacarpal inserted tooth, in the abrasive formation or directional well and horizontal well, can reduce the wear of the teeth dorsal, improve the performance of bit gauge protection, and prolong the service life of the bit.
Steel tooth bits
111/114/115/116/117
It is suitable for very soft formation with low compressive strength and high drillability, such as clay, mudstone, chalk and so on.
211/214/215/216/217
It is suitable for medium formation with high compressive strength, such as medium soft shale, anhydrite, medium soft limestone, medium soft sandstone and hard interlayer.
214/217/314/327
It is suitable for soft and medium- -soft strata with low compressive strength and high drilability, such as medium soft shale, medium soft limestone, medium soft sandstone and soft stratum with hard interlayer.

TCI bits
435/437
It is suitable for soft and medium- soft strata with low compressive strength and high drillability, such as clay, mudstone, chalk, gypsum, salt rock, soft shale, and soft limestone.
517/537
It is suitable for soft formation with low compressive strength, such as mudstone, gypsum, salt rock, soft shale, and soft limestone.
615/617
It is suitable for medium- hard formations with high compressive strength, such as hard shale, limestone, sandstone, and dolomite.
637
It is suitable for hard formation with high compressive strength, such as sandstone, limestone, dolomite and anhydrite, and marble.
Designed & developed according to the construction requirements and market demand, trenchless cone palm can be applied to various formations and drilling tools, achieving a full coverage of 8-1/2 to 12-1/4 inch. Adopting the steel ball locking sliding bearing and the bearing surface is welded with wear-resistant alloy, which has high wear-resistant performance and longer service life.
Single cone rotary drilling bit, which can be applied in various rock layers from strongly weathered rock to slightly weathered rock, and adapt to the formation compressive strength of 50MPa to 150MPa or above.
PDC Bits
Double rows
The maximum local cutters equivalent density, improve the offensive and abrasive resistance of the bit in hard and abrasive formation.
PDC updrill
Brazing high quality PDC cutters at specific angle, when resistance during trip-out and back reaming in easy shrinking interval, it can effectively remove the obstacles, protect the bit body from harm.
Limiting Cutter
Effectively control the front PDC cutter to drill into the depth, improve the stability and reduce its drift.
Shock- absorbing cutters
It makes the bit diling more smoothly,to prevent the PDC cutter damaged in advance.
Arc PDC cutters gauge
High quality arc PDC cutters gauge, reduce the abrasion of rock on the bit’s body, increase wear resistance and stability of the drill gauge.
