Cutting Structure
Enhancing the wear-resistance of teeth with high-density premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit. Reinforcing the compressive mechanical properties of inserts by using premium tungsten carbide insert with new formula and new techniques for insert bit.
Gauge Structure
Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capabilities and seal protection.
Bearing Structure
High precision journal bearing with two thrust faces. Balls lock cone.
Hardfaced 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 HNBT O-ring, best seal compression and radial seal structure can enhance the seal performance. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
Product Application
It can absorb high WOB in the conventional drilling. It is applicable for various formations by matching cutting structure with different teeth shape, teeth density and teeth exposure height.
