The coolant pressure and flow rate recommendation above represents a good approximation to obtain optimum tool life and chip evacuation at AMEC recommended speeds and feeds. For a more specific approximation of coolant requirements, consult the formulization below or the AMEC Engineering Department.
Although the above pressure and flow recommendations produce attractive tool life and chip evacuation, the T-A® Drilling System will still function quite adequately if lower coolant capabilities exist. Call our Engineering Department for specific recommendations.
