Product Description
Good quality High efficiency ~ water well drill bits
1. 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
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
