Radial drilling machine

The radial drilling machine is intended for drilling on medium to large and heavy workpieces. It has a heavy round column mounted on a large base. The column supports a radial arm, which can be raised or lowered to enable the table to accommodate workpieces of different heights. The arm, which has the drill head on it, can be swung around to any position. The drill head can be made to slide on the radial arm. The machine is named so because of this reason. 

The radial drilling machine may be Plain, Semi universal or Universal type. In a Semi universal type, the drill head can be tilted right or left to drill angular holes. In a universal type, the drill head can be tilted left or right and front or back to drill holes in a compound angle.
