1 Advantage
Optimized short parabolic profile,suitable for drilling soft to medium soft homogeneous formations.
Evolute asymmetrical blade cutter placement design and balanced bit load so that bit whirl is pervented
Composite gage protection and low torque design imporve rate of penetration
CFD hydraulic blance design results in nbetter bit cleanding1 and cutting removal.
Combined utilization of high performance PDC compacts significantly prolongs bit life.
