A boring machine provides a pair of motor-driven drills mounted to a template so that the drill chucks are aligned in parallel, side-by-side arrangement in a housing beneath the template. A guide mechanism, including a front plate with a pair of guide holes, is also mounted beneath the template, with a pair of spring loaded guide rods extending from the front plate to the housing. A pair of stops are positioned between the front plate and the housing providing a limit to travel of the front plate.
