First-time buyers price the rig and stop there. But the rig is only about half of a working HDD setup. This guide breaks down all seven components (rig, locator, mud system, drill pipe, tooling, trailer, ancillary), what each costs used, and three example builds with honest all-in totals, plus what you can safely defer.

What size directional drill do you need? It is a buying question disguised as a technical one. This guide maps job type to size class (mini, utility-mid, mid-heavy, heavy) with verified pullback ranges and example used models, explains the specs that matter, flags the rock exception, and shows how to avoid the costly over- and under-buying traps.

If you are about to spend eighty to two hundred thousand dollars on a used directional drill, the next two hours of your life matter more than any number on the sticker. This is the inspection sequence we use to accept machines into WorldHDD inventory.
