While large utility drills can be efficient on many intermediate projects, pilot bores at longer distances and in challenging ground conditions require larger-diameter drill pipe to deliver higher volumes of drilling fluid. Larger pipe requires greater torque to make and break connections, which means stepping up to a larger drill.
