PDC Bit

♦

We design and produce specified 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 suitable blades shape and cutter direction to get high drill speed and stable drill.

♦

Gravel/limestone/shale/clay stone/tuff: Round crown and reasonable cutter direction. Drill smoothly in good speed.

♦

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 smoother.

♦

Authoritative API standard and ISO certification, quality and service will be better ensured.
