12 1/4 inch IADC537 Tricone Bit
High quality tungsten carbide inserts with the latest technology are adopted to improve the comprehensive mechanical properties of the bit.
Multiple gauge protection with gauge trimmers on the heel of cone,tungsten carbides insert and hard facing on the shirttail increases holding capability and bearing life.
High precision journal bearing with two thrust faces. Balls lock the cone. Hard faced head bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver plated. Abrasion resistance and seizure resistance of the bearing are improved.
Seal and Lubrication
Premium HNBR O-ring,optimal seal compression and curved seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
It can bear high WOB in the conventional drilling. It is suitable for various of formations by matching cutting structure with different tooth shape,tooth density and tooth exposure height.
