The high compressive strengths, hardness and abrasiveness characteristic of quarry rock, pose a high demand for a drilling tool, both in terms of rates of penetration as well as wear resistance.


Drillco’s new quarry hammer produces a very high power output. This hammer is simple and light, but at the same time it is a robust tool to provide high durability as well as very high penetration rates.
