Structure Features:

1. Adopting non-isometric deflection of tooth arrangement, tooth shape and tooth height was optimized.

2. The use of the most advanced metal sealing technology increases the reliability of the seal. It can stably drilling at high speed and high temperature.

3. New materials are used for the bit tooth and roller to reduce the friction between the back of the tooth and the well wall, improve the quality of the well wall, and protect the tip and seal of the tooth.

4. Bit’s bear is enhanced treatment, and prolonging the bit working life, reducing the drilling cost. (The drill bit bearing has been strengthened to make its working life longer, saving the cost of drilling.
