Drill Bits for Drills in Mining

 

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
