The unique special designed impact surface of the working tool, is impeccably flat (to a degree not visible with naked eye) allowing the piston to hit the working tool on the full surface, transferring the maximum energy transmission to the rock.
Epiroc working tools are manufactured from a special alloy with a very high grade of purity. High purity minimizes the risk of tool breakage by reducing weak spots, which could cause cracks.
An optimum hardness ratio between the working tool impact surface and the piston is of key importance.
Epiroc working tool quality starts from the selection of the best raw material available, followed by an advanced machining process and state-of-the-art heat treatment, allowing all working tools to have exactly the same properties.
