A drilling machine for boring holes in a surface includes a main frame to which a drill gang assembly is rotatably and telescopingly mounted. The drill gang assembly includes a drill support frame supporting a plurality of drills in parallel spaced alignment. The drill gang assembly is mounted on a mast which may be rotated relative to the main frame about a vertical axis up to at least one hundred and eighty degrees. The drill gang assembly is also pivotally mounted relative to the mast to permit pivoting of the drill support frame and attached drills about a horizontal axis.
