What is Downhole Drilling Assemblies? Definition from

The downhole drilling assembly is actually a collection of equipment which forms the active drilling part of a Horizontal Directional Drilling machine. Due to the high stress environment involving torque provided by the drill string, the weight of the equipment pushing against the tunnel face and the presence of drilling fluid, the downhole assembly must be very robust.
