BIT CHARACTER
These types of bit have some common features, as follows:
1. Force balanced, resist impact to the blade during high-speed drilling, to make bit work stable.
2. Plus wear knot section, reduce collision in the high-speed rotational vibration.
3. Patented matrix formulation, extended bit life.
4. Optimal hydraulic design, easy to move out the drill cuttings and cooling.
5. Equipped with back reaming teeth.
6. The cutter is high performance to increase the ability of anti-impact and anti-abrasive.

• SOFT TO MEDIUM FORMATION DRILLING
Parabolic profile with medium to lower cutter density helps to obtain better
ROP in soft to medium formations with low compressive strength and small
abrasive layers.
• DURASET GAUGE
Super strong material promotes gauge wear resistance to provide long bit life.
• UNIQUE BACKRACK DESIGN
The cutter’s backrake has been unique design, reducing the bit torque
and increasing aggressiveness.
