KAT DRILLING
1 / 5
Extension rods are manufactured using high-quality hollow drill steels. These rods are available in two primary configurations: Round type and Hexagonal type. The central hollow passage, commonly referred to as a flushing hole, is essential for the transmission of water or air to facilitate debris removal during the drilling process. The integrated threads are designed for seamless connection with couplings, shanks, or drill bits.
