Steel body pdc bit 17 1-2” S1665 /S423
Description
Features
Deep blade and long parabolic configuration
design,ensures optimal bottom hole flow pattern and anti-balling.
Optimize the cutting structure and places high quality cutters at different points, increases wear resistance and offensive of the bit .
Anti-whirl design improves ROP and enhances drilling stability.
Deepened Blade
Unique deep blade design ,lessens the torque, increases the footage capability and rate of penetration of the bit.
Gauge
Unique gauge with high quality PDC cutters, helps several-fold increasing wear resistance and stability of the bit.
High Density Cutters
High density PDC cutting structure design, ensures efficient reaming and dilling while extending the application and performance range of casing running operation.
Shock-proof Insert
Shock-proof insert lessens the vibrations while rilling, restores
smooth dilling, significantly increases the steady and life of the bit
