Extension rods are manufactured from high-quality hollow drill steels. They are available in two primary shapes: round and hexagonal. The central hollow hole, known as the flushing hole, is essential for transmitting water or air during the drilling process. The integrated threads allow for secure connection to couplings, shanks, or drill bits.
