The Roughneck R200 2-inch rock hammer from HammerHead Trenchless is engineered specifically for horizontal directional drilling applications. It is designed to expand the capabilities of small utility drills, allowing 7,000- to 10,000-pound-class directional drills to effectively drill through solid rock as well as other difficult soil conditions. The unit drills a 3.125-inch pilot hole. Electronic controls allow the operator to adjust the airflow with the touch of a button from open to closed and anywhere in between, allowing them to manage the power of the hammer on the fly. 800-331-6653; www.hammerheadtrenchless.com.
