Matrix Body PDC
Which is a matrix body PDC bit using arc-type double rows design with eight spiral blades and long parabolic profile with high wear design,effectivey improve the pdc bit impact resistant and abrasive resistant,thereby improving the rate of speed.Balanced by hydraulics esign,with each blade cutting the amount of displacement is proportional to te volume of cuttings transport to match the drill cuttings transport capacity optimization.Submarine shaped likehigh brasin protection and debris flow path design enables streamlned channel formation,which prevents balling trend caused by the swirl and eddy.Dynamic flow simulating technology is uesd for hydraulic design to ensure optimum bottom hole flow patters and anti-balling.
Suitable for high compressive strength,high abrasive hard and tight formations,such as Limestone,Calcareous Shale,Siliceous Sandstone,Siltstone.
TCI 437 Soft formation TCI Tricone bits
The 437 tci bits are used to drill low compressive strength very soft formation tci bits maximize
the use of both conical and chisel tungsten carbide inserts of large diameters and high projection.
This cutting structure design combined with maximum cone offset ,results in high bit penetration
rates.the deep intermesh of cutter rows prevents bit bailing in sticky formations.
TCI 517 medium formation TCI Tricone bits
The 517 features aggressive chisel tungsten carbide inserts on the heel rows and inner rows this
design 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.
TCI 617
TCI tricone bits 617 features robust chisel tungsten carbide inserts on the heel row and conical
on the inner rows .this design provides a fast drilling rate and added cutting structure durability in
medium to medium hard formations . the HSN rubber o-rin provides adequate sealing for bearing durability .
TCI 637 can be used to drill hard and abrasive formations
wear –resistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge.
maximum numbers of hemispherical-shaped inserts are used in all rows to provide cutter durability and long life.
Steel Body PDC
Use high-quality steel to make the base material of PDC bit, the surface of the blade weld high-performance
wear-resistant materials, the use of computer software for the overall design of three-dimensional PDC BIT,
double asymmetric teeth straight blade, medium parabolic crown, long Gage shape structure.
Cutting structure using force balance design, unique PDC cutter layout and positioning of the PDC bit to
keep a sharp cutting edge in drilling, effectively improve the offensive PDC BIT and drilling speed.
The application of fluid dynamics analysis and numerical simulation of hydraulic flow field analysis
technology to design, help to improve chip speed drill and anti-balling capacity.
Suitable for high compressive strength, with abrasive medium hard to hard formations, such as shale,
limestone, anhydrite, sandstone and so on.

Steel tooth bits series:
Soft formation tooth bits:
The soft formations tooth bits are used to drill low compressive strength, soft formations. Long projection
tooth lengths are used on high offset cones to provide the greatest penetrations rates possible. Wear
resistance hard facing is used to control tooth wear. On the softest bit types this hard facing completely
covers the bit teeth.
Medium hard formations tooth bits:
The medium hard formation tooth bits are used to drill high compressive strength, medium hard formations.
Shoot projection teeth with reduced crest length are used in this series of bit designs.
Durable hard facing is applied to reduce tooth wear.
