This gasoline engine-powered road building drill has been designed specifically for the purpose of drilling test cores from holes in roads, airport runways, bridges, etc.
The machine consists of two vertical support columns, which carry the drill head/engine assembly accurately with the help of a screwed spindle.
The 6HP gasoline engine with pulley mechanism works with minimum vibrations. The double precision bit advances with a screwed spindle, which provides a constant, accurate drill pressure, minimum core chipping and long bit life.
The complete assembly is supplied on a rigid metal base with leveling facility, and is suitable for coring applications in a vertical downwards motion only.
