(TCI) Detailed Product Description

We sell 3 1/2(88.9mm) to 17 1/2"(445mm) tricone rock bit with good quality and service.

1. Journal bearing. hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver plated. the load capacity and seizure resistance of the bearing is greatly improved.

2. O-ring seal is made of the more wear resistance high saturated Buna-N with the section and precisely designed sealing flange in the cone sealing area increased the reliability of the seal.

3. The bit bearing is ball which can be applied to high rotary speed drilling.

4. All rubber compensator is used which can provides the bearing system with good assurance of lubrication.

5. New type of grease that can sustain high temperature up to 250C is utilized.

6. High wear resistance and excellent cutting ability of the insert bit are given full play by using carbide compacts of high strength and high toughness in combination with optimized compact numbers and rows, the exposure height and special shaped compacts.

 PDC bit, diamond bit, PDC core bit, PDC bits

1. Circular arc brown, standard PDC cutters are distributed on the blades.
2. Cutters distributed optimized with balance design so that the stability and gain efficiency of drilling largely improved.
3. Column diamond is used in inner and outer gauge as protection, besides that extra PDC cutters are used to enhance gauge protection. Flow room age is optimal designed so that bit can be clean and cooled sufficiently.
4. This series of bits are suitable for medium to medium-hard formation.
