Which type of drill is designed to accommodate large workpieces by maneuvering an overarm in place?

The radial drill is specifically designed to accommodate large workpieces, making it suitable for tasks where size and maneuverability are critical. Its distinctive feature is the overarm that can be adjusted in both vertical and horizontal directions. This flexibility allows the operator to position the drill bit exactly where it's needed on a large component, enhancing precision and efficiency in drilling operations. Additionally, the radial arm can swing around the column, enabling access to various areas of the workpiece without the need to reposition the entire setup, which is particularly advantageous when working with heavy or cumbersome materials. This versatility is a key reason why radial drills are preferred in applications involving large workpieces compared to the other types of drills mentioned.
