Products covered all IADC codes 
Specialized in single bits, tri-cone bits and PDC bit

1. Material: tungsten carbide

2. Various types for different formations

3. Cutting structure: The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit

4. Gauge structure: Multiple gauge protection with trimmers on the heel of cone, tungsten carbide inserts and hard facing on the shirttail increases gauge holding capability and bearing life

5. Seal and Lubrication: Premium O-ring, optimal seal compression and curved seal structure can enhance the seal performance. The compensator system and advanced grease can greatly increase the lubricating reliability.

6. Bearing Structure: High precision bearing with two thrust faces. Ball looks the cone. Hard faced head bearing surface inlaid with friction-reducing alloy and the silver-plated. Abrasion insistence and the silver-plated. Abrasion insistence and seizure resistance of the bearing are improved.

7. Product application: It can receive high WOB in the conventional drilling. It is suitable for various formations by cutting structure with different tooth shape, tooth density and tooth exposure height.

8. All IADC code available in our company
