2)Application:
Suitable for soft to medium hard formations.
Feature:Improved support and retention
Advantage:Manage the magnitude cutter loading and bit torque.
Benefit:Improved bit durability and directional responsiveness
1,Suit for drilling medium soft to medium homogeneous formations.
2,Evolute asymmetrical blade cutter design and balanced bit load so that bit whirl is prevented .
3,Composite gage protection and low torque design improve rate of penetration .
4,CFD hydraulic balance design results in better bit cleaning and cutting removal .
5,Combined utilization of high performance PDC compacts significantly prolongs bit life .
3.Advantage:Higher nozzle counts and/or fixed ports to best serve cleaning,cooling and cuttings evacuation requirements with available hydraulic flows.Allows for higher flow rates with minimal increase in pump pressure.
Feature:Diamonds are impregnated in the matrix behind the PDC cutters
Benefit:Increased footage drilled in abrasive applications
