1.70HRC soldering surface
2. Good impact-abrasion resistance
3. Optimized Hydraulics
4. Lowest Vibration design
PDC drill bit is mainly used to drill Oil well, gas well, water well, etc.
We design and produce specifie PDC bit with good performance for each soft, medium and hard formation.
Clay stone/lignite/siltstone/sands: We design 3-5 blades with low density cutter placement, large slot. Low cost, high speed.
Mudstone: We have experience to design suitalbe blades shape and cutter direction to get high drill speed and stalbe drill.

Thank you for your time to view our website. I am the organizer of PDC Bit project with 6years experience in designing, manufacturing and field operation. It is great honor to introduce our PDC bit to you and have change to cooperate hand in hand.
Hospital Wolfni friend are waiting for your factory site view. The best wish for you! ! !
Gravel/limestone/shale/clay stone/tuff: Round crown and reasonable cutter direction. Drill smoothly in good speed.
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.
