1,Application:
1,Suit for drillingmedium to medium-hard formations.
2,Evoluteasymmetrical blade cutter design and balanced bit load so that bit whirl isprevented .
3,Composite gageprotection and low torque design improve rate of penetration .
4,CFD hydraulicbalance design results in better bit cleaning and cutting removal .
5,Combinedutilization of high performance PDC compacts significantly prolongs bitlife
Higher nozzle countsand/or fixed ports to best serve cleaning,cooling and cuttings evacuationrequirements with available hydraulic flows.Allows for higher flow rates withminimal increase in pump pressure.
Feature:Diamonds areimpregnated in the matrix behind the PDC cutters
Benefit:Increasedfootage drilled in abrasive applications
