KAT DRILLING
1 / 5
Extension rods are manufactured from high-quality hollow drill steels. They are available in two primary configurations: round type and hexagonal type. The central hollow hole, known as the flushing hole, is essential for transmitting water or air during the drilling process. These rods feature precision threads designed for connecting couplings, shanks, or drill bits.
