A radial drilling machine is an item of metalworking equipment that consists of a drilling head that is mounted on its side along a radial arm. The drill can be raised, lowered and rotated on the vertical arm in order to drill workpieces of various sizes and dimensions. The bit on a radial arm drill is often fitted with gears, so quick changes can be made to the rotating speed. Workpieces that are too large to fit into table-based drills are usually processed using a radial drilling machine.
- Drilling of heavy and large workpieces
- Used in all industrial sectors
- The ability to switch tools quickly allows for comprehensive machining tasks

The crucial parts of a radial drilling machine are the arm, the column and the drill bit. The drill can be can be moved relatively easy along the vertical axis, which is ideal for drilling irregularly shaped workpieces. Versatile, relatively safe and accurate, the radial arm drill is used for countersinking, boring holes and, occasionally, grinding small particles from masonry. While some radial drilling machines are set up for use on a floor, most are mounted onto tables or benches. The drill moves during production, rather than the workpiece. This means it is relatively quick and easy to process several workpieces of different shapes and sizes on the same radial arm drill.
