Features extension rods

An extension rod is made of high quality steel, its properties include:
• A superior tolerance for any bend of the rod 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.

Round or Hexagonal Extension Rods

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. Rocbo offers these extension rods in different threads.
