ZLCONN Tricone Bit PDC

PDC bits used as HDD pilot bit is more and more common in these days. 

When comes to the soft and medium soft formation like sandstone, lime stone, the penetration speed can be multiple times faster than the conventional tricone bits. 

ZLCONN PDC Pilot bit are specially made for HDD Machine application. It chooses most efficient cutters and blade design to maximize the working life.

Steel is metallurgically opposite of matrix. It is capable of withstanding high impact loads, but is relatively soft and, without protective features, would quickly fail by abrasion and erosion. Quality steels are essentially homogeneous with structural limits that rarely surprise their users.

ZLCONN Tricone Bit PDC Product Features

  • Steel PDC bit with five blades of parabola crown profile and with middle cutter density.
  • With interchan geable screw nozzles.
  • Asymmetrical blades arrangement and special load-balanced cutter arrangement design improve bit stability and therefore higher ROP.
  • Non-plane interfaced diamond /carbide cutters absorb effectively high stress and minimize cutter fracturing and wearing.
  • Both tilted and cauterized nozzles design improves bit cleaning and prevents bit balling,thus to improve ROP.
  • Can be used on rotary or down hole motor drilling.
  • Suitable for soft to medium hard formation.
  • High HIS is recommended.
