Earth boring up to 20 inches is a method for digging poles.

Earth boring is used to dig holes for poles up to 20 inches in diameter because it creates a clean, cylindrical bore with stable sidewalls that fit the pole snugly and allow proper embedment. It’s efficient for this size, minimizing surface disruption and work compared with manual digging. Water jets can loosen soil but don’t reliably produce the precise, deep, large-diameter holes needed for standard pole installations. Blasting is unsafe and impractical for routine pole work, and hand tools are simply too slow and labor-intensive for a 20-inch hole.
