Horizontal Directional Drilling (HDD) continues to be the most popular method of installing electrical cable, fiber optics, utility conduits and irrigation lines in industrial, commercial
and residential applications. This technology eliminates the need for open trenching to install utility lines and surface obstructions can be avoided with minimal environmental
disturbance and limited interruptions to traffic or services. Mills Machine has been manufacturing horizontal drilling bits, holeopeners and horizontal
road boring bits for over twenty years.
