tci bits,tricone bit,rotary bit - 12 1/4

1.Introduction

1 material: cabide

2 suitable for very soft with low compressive strength,such as clay, soft marl,unconsolidated standstone,etc.

3 Cutting structure: the durability of premium diamond insert is improved with new formulas and new techniques for insert bit.

4 Guage structure: Multiple guage protethion with trimmers on the heel of cine,tungsten carbide inserts and hard facing on the shirttal increases guage holding capability and bearing life.

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

6 Bearing structure: High precision bearing surface inlaid with friction-reducing alloy and the silver-plated.Abrasion insistance and the silver-plated.Abrasion insistance and seizure resistance of the bearing are improved.

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

From 1.8 inch (45mm) to 26 inches (660mm)Note: sizes and types that are not shown above can be customized according to specific drilling requirements

2.The main structure features:

This series inserted bits adopts non-isometry teeth placement in combination with optimized teeth height and shape.

Applying the world's latest sealing technology- metal face sealing ensures the bearing sealing is more efficient,and more suitable for drilling at high rotary speed and high temperature working condition.

New material is applied on the part of gage protection,and reducing the friction from back of leg to well wall,improving quality of the well wall, protecting the back of the leg and seal.

Bit;s bear is enhanced treatment, and prolonging the bit working life, reducing the drilling cost.
