A fluid channeling device () is for a down-hole drill assembly () having a central axis () and advanceable into a hole in a downward direction (D) along the axis (). The assembly () includes a drill member () with an inner surface () bounding a central bore () and an outer surface (). The channeling system includes at least one passage () provided within the drill member () so as to extend generally between the drill member inner () and outer surfaces (). A generally annular channeling member () is disposeable about a portion of the drill member () and has at least one inlet port (), at least one discharge port (), and a passage () extending between the inlet () and discharge ports (). The inlet port () is fluidly connectable with the drill member passage () to fluidly couple the central bore () with the discharge port (). The discharge port () is configured to direct fluid generally externally of the drill assembly () and generally in an upward direction (U) along the axis ().
