Abstract
Implementations of the present invention include a drill rod guide configured to align a first drill rod and a second drill rod. The drill rod guide includes a cylindrical section and a tapered or frusta-conical section. The cylindrical section is sized and configured to concentrically surround a first drill rod. The tapered or frusta-conical section is sized and configured to guide a second drill rod into the cylindrical section and into alignment with the first drill rod. The drill rod guide may include first and second guide members that form symmetrical halves of the drill rod guide. The first and second guide members may be connected to first and second jaws of the clamp. The guide may include a window configured to allow a user to visually confirm that the first and second drill rods are aligned.
