1. Hard-facing
2. Better cutting capability
3. Oil drilling
4. Good erosion-resistant.
Advantage
1.Suit for drilling medium hard to hard formations.
2.Evolute asymmetrical blade cutter design and balanced bit load so that bit whirl is prevented .
3.Composite gage protection and low torque design improve rate of penetration .
4.CFD hydraulic balance design results in better bit cleaning and cutting removal .
5.Combined utilization of high performance PDC compacts significantly prolongs bit life .
6.Improved bit durability and directional responsiveness.

Applications:
|
||||||||||
|
•
|
Used in many fields such as : Oil well, gas well, water well, etc.
|
|||||||||
|
•
|
Formation: Suit for drilling medium, medium-soft and midium-hard formations.
|
|||||||||
|
•
|
Well type: Suit for helical well, inclined well, lateral well.
|
|||||||||
|
Performance:
|
||||||||||
|
•
|
Low torque spiral design and software designed tooth reduce the cutting edge wear & increase life
(no repair life up to 8300M/pc).
|
|||||||||
|
•
|
The unique parabolic crown-shaped design and tooth balance design keeps smooth drilling under high speed.
(Speeds up to 30~40m/h.)
|
|||||||||
|
•
|
Raw materials: Alloy steel with a special treatment, achieve better mechanical properties
(Rp0, 2: 1200MPa; Rm: 1100 MPa)
|
|||||||||
|
•
|
Steel body with hardening tungsten carbide surface(WC),make the drill bit both high strength and very strong abrasion resistance.
|
|||||||||
|
•
|
Dedicated PDC cutter can improve the life and shield the risk of complex formation drill not passed.
|
|||||||||
|
•
|
The scientific drilling dynamic equilibrium design and hydraulic balance design make the drilling process more smooth.
|
|||||||||
|
•
|
Authoritative API standard and ISO certification, quality and service will be better ensured.
