1)Features:

1.Cutting structure is force balanced and bit blade is asymmetrically designed so that the load on bit is balanced that resulting better stablity of the bit.

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

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

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

5 .Hydraulic systems of the bit is optimized using dynamic flow pattern simulation technology enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.
