Summary:A drill string comprising a bit portion, a distal extension portion, a proximal extension portion, and a connecting portion. The bit portion is operatively connected to the distal extension portion and the connecting portion operatively connects the distal extension portion to the proximal extension portion to define supply path and a return path. The supply path extends through the distal proximal extension portion, the connecting portion, the distal extension portion, and the bit portion to a cutter region associated with the bit portion. The return path extends from the cutter region through the bit portion, the distal extension portion, the connector portion, and the proximal extension portion.
