Apparatus for drilling horizontal holes includes a frame for holding a drill, and the frame is supported by a single wheel adjacent to the drill and dual wheels at the opposite end of the frame from the drill. A cable system is utilized for moving the drill inwardly toward the work and outwardly away from the work by a single operator. A single operator can also move the frame as required at the work site. Multiple drills may also be secured to the frame, so that a plurality of holes may be drilled substantially simultaneously.
