1)Features:

1. Cutting structure is force balanced and bit blade is asymmetricallydesigned so that the load on bit is balanced that resulting better stablity ofthe bit.

2. Main cutter is high performance PDC cutter to insure service life of thebit while improving ROP.

3. Cutter exposure is optimized to insure the bit can achieve higher ROP issoft to medium formations.

4. Shock absorbers are designed to make the bit capable of drilling throughformations with hard strigers.

5. Hydraulic systems of the bit is optimized using dynamic flow patternsimulation technology enhance cleaning and cooling effects of the bit toeffectively prevent bit from balling.
