Product Description
Application
1,Suit for drilling medium to medium-hard 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
6,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.
