8 1/2 inch pilot PDC drill bits 490mm hole opener
Introduction of PDC drill bits:
♦ Steel body with hardening tungsten carbide surface(WC),make the drill bit both
high strength and very strong abrasionresistance.
♦ 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.
