KAT DRILLING
1 / 5
Extension rods are manufactured from high-quality hollow drill steels. Available in two primary shapes: Round type and Hexagonal type. The central hollow hole, commonly known as a flushing hole, is designed for the efficient transmission of water or air during drilling operations.
The threads are engineered for seamless connection with couplings, shanks, or drill bits. Standard thread options include R22, R25, R28, R32, R38, T38, T45, T51, ST58, and T60. Available lengths range from 600mm to 6400mm.
