The low profile and bit body
| The optimized cutting structure |
 Adopts the low parabolic profile and short gauge design. The length of the bit body can meet the requirements of rotary steerable tools for the best performance. The design can improve the steerability and stability of the PDC bit. |  Adopts the ECL cutter placement and the patented mechanics analysis software to adjust and optimize the dimensional placement of cutters, improve the steerability and bit life. |
| Gauge design | Optimized hydraulics |
 Adopts the active gauge design to reinforce the lateral aggression and gauge effect. It can adjust the lateral agressive effect according to the different well trace. |  According to the different rotary steerable tools'different requirements to TFA , combining the different drilling condition to optimize the hydraulics of bit through computational bottom hole fluid simulation analysis and the patented hydraulics analysis software. |
| Additional design | |
 According to the different formation and drilling condition, relevantly add the wear knot, damping cutter and secondary cutters to improve the bit performance and increase bit life. | |
