Everdigm Durawing

When using a Durawing system, of the Korean Everdigm, you will drive the casing with a DTH-hammer all the way to the desired depth, after which you withdraw the concentric elements and drill further. The advantages of this technological approach, as opposed to the more common eccentric system, is that there is no blocking caused by stones or gravel. Agiva can deliver a system with various diameters and different currently in use shank types.


  • Its unique removal mechanism makes it the absolute most practical tool of all tools.
  • Easily replaceable parts.
  • Low operation costs.
  • Identical results when drilling horizontally.
  • Internal air circulation ensures that blockages are prevented
