Downhole Tools
Nozzles
Nozzles control fluid flow from the pipe to the bore. Select nozzles that will supply
at least the amount of
fluid per minute needed for the flow and pressure you will be using. A nozzle that will supply more fluid per
minute is recommended. See your Ditch Witch dealer for nozzle recommendations.
Bits
Selection
These charts are meant as a guideline only. No one bit works well in all conditions. See your Ditch Witch

Selector at
