Horizontal Drilling 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, hole openers, and horizontal road boring bits since 1979. We also officer two types of Horizontal Road Boring bits, Free Bore and Casing Push type. Both of these designs feature steel tooth or tungsten carbide button roller cone bit segments with sealed bearings in new, retip, or rerun condition. This catalog section features Claw, Blade, or Roller Horizontal Holeopeners and Back Reamers.
