Introduction of PDC drill bit:
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.
Raw materials: Alloy steel with a special treatment, achieve better mechanical properties (Rp0, 2: 1200MPa; Rm: 1100 MPa)
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. )
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.
