For horizontal drilling processes, the 2000 series AutoDrill shown is perfect. 

The self contained feed control (sometimes called Hydro Feed or Hydro-Brake) is excellent at creating a cleaner hole breakthrough process. It also improves the hole roundness in thin sections and provides control when hole boring smaller holes. By using a feed control, AutoDrill is also able to manage the Horsepower required on some larger hole processes or when two-speed operation is desired.
