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 HARD FORMATION DRILLING
Medium short parabolic profile and medium cutter density helps
to obtain better ROP in soft to medium hard formations with
lower compressive strength and small hard layers.
• DURASET GAUGE
Gauge cutter promotes gauge wear resistance to provide the long
bit life.
• IMPROVED HYDRAULICS
Deep shank maximizes junkslot area for better bit cleaning.
Taperedblades allow larger face volume for improved hydraulics and ROP.
• POLISHED CUTTERS
Highly polished cutter surfaces reduce shear forces, improving cuttings
removel, ROP and drilling efficiency
