Ejector Drilling

Ejector drilling is a limited alternative to BTA deep hole drilling, using a dual tube system, and both internal and external coolant . High pressure coolant is introduced between the inner and outer drill tubes, and exhausted through an adapter mounted to the front of the machining spindle . Ejector drilling is typically used to retrofit lathes and machining centers, but is limited in efficiency, depth-to-diameter drilling ratios, and chip and fluid removal.
