Used for horizontal bore jobs. Allied Hole Hog underground piercing and pipe pushing/pulling missle tools are the most efficient, least expensive method for underground pipe or service placement in construction and installation work. Pneumatic Hole Hog missiles open clean, compacted, self contained tunnels for pipe, cable, conduit or wiring at the lowest cost per foot. Hole Hog moles eliminate the need to break pavement or disturb landscaping from trenching or open cuts. There's no reason to disrupt traffic by tearing up and restoring asphalt or concrete or to have callbacks for settling backfilled trenches. That's because Hole Hogs break through the ground while horizontal boring under roads, driveways sidewalks, parking lots, runways, foundations, or virtually any obstacle. Also known as a pneumatic gopher or missile or Trench less pipe install tool or boring missel or boring missile
