Various embodiments include methods and apparatus structured to increase efficiencies of a drilling operation. A drilling apparatus can be structured to include a hammer drill to move a hammer to impart impact force to a bit box in conjunction with a rotary drive shaft. The hammer drill can be arranged as a mechanical drive hammer capable of being applied to both fluid drilling and air drilling. Additional apparatus, systems, and methods are disclosed.
