HDD Drill Rod vary with the specifications of
the Drill Machine. Drill rod sizes range from
1.6” diameter X 6’ long to over 6” diameter X
30’ long.
The Drill Rod conveys the drill fluid
down hole and transfers the Thrust and
Rotation of the machine to the drill head or
backreamer underground.

Each length of rod is threaded
together by the machine and
tightened to a specific torque.

After the rod is coupled together, it is drilled
into the ground using thrust, rotation, and
fluid.

Back Reaming is the process of
opening and stabilizing the bore hole to
the appropriate size for installing the
pipe.

Back Reaming uses the reverse thrust,
rotational torque, and drill fluid flow of the
drill machine.

Pre-reaming
Pre-reaming is a technique used to incrementally
increase the diameter of the bore hole before
making the product pull.
Pre-reaming is used for all types of ground
conditions, product sizes, and bore lengths.
Pre-reaming is one of the simplest techniques to
insure success.
