Each type has its own unique design and is used for specific drilling applications. Straight extension rods are used for drilling straight holes, tapered extension rods are used for drilling holes with a conical shape, and threaded extension rods are used for attaching different types of drill bits to the extension rod.

The hex shank design offers several advantages over traditional round shanks. Firstly, the hex shank's non-circular profile allows for better torque transfer, minimizing the chances of the bit slipping in high-torque applications. This is particularly beneficial when working with harder materials or when drilling deep holes. Secondly, the hex shank is compatible with quick-change tool systems, enabling faster bit changes without needing a chuck key, thereby saving time and increasing productivity.
