Product Description-----high quality PDC drill bit :
1. Cutting structure is force balanced and bit blade is asymmetrically designed so that the load on bit is balanced that
resulting better stability of the bit.
2. Main cutter are high performance PDC cutters 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 system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and
cooling effects of the bit to effectively prevent bit from balling.

More Information of PDC bit
PDC bit used in many fileds such as:Oil well,gas well,coal,water well,etc.
• Deep blade and long parabolic configuration, ensure optimal botton
hole flow pattern and anti-balling.
• Anti-whirl design improves ROP and enhance the drilling stability .
• Arc blade and spiral gauge enhance the cutting cag-ability and the
drilling stabilization.
• Medial cutter density is suitable for soft to medium soft formations.
