Extension rods
|
For extension of drill rods and drilling depths of more than 10 mtr. When the length of a single drill rods is not long enough, an extension rod can be used. An extension rod is attached to a drill rod usually through a coupling. In this way, drilling is possible to great depths. Features extension rods The extension rods are made of high quality steel. Properties are a superior tolerance of any rod bending and the best protection against steel exhaustion. The parts of the rod which are under great pressure, namely the surface of the shank- and the thread ends are hardened. The flushing channel has a special anti-corrosion layer to prevent corrosion from within. These are features which minimize risk of breaking the extension rod and to guarantee the optimal lifetime. Extension rods are round or hexagonal. Round rods consist of less steel and are therefore lighter and slightly cheaper. However, the most commonly used rods are hexagonal. These rods are more fixed and therefore the drilling results are often straight and the drilled material is better disposed. Increasing the drilling, a longer life and lower costs per drilled meter.
