What Does Rotary Rod Machine Mean?
A rotary rod machine is a drilling machine – used in horizontal directional drilling – that uses a bit attached to a rod to drill through the earth. Unlike in auger, the rotary rod machine is not equipped with hex couplings and a flighted drive to move the spoil from horizontal drilling that to the machine.
Instead, rotary rod machine uses drilling fluid to flush the spoil to the surface where it is removed by specialized mud-recycling systems, screens, and filters.
