FAQ:

1. What is rock drilling?

Rock drilling tools include those used for oil and natural gas exploration, mining, construction, and all other industrial operations that need to excavate or drill through natural rocks, concrete, and masonry.


2. What is the weakest rock in the world?

In regions with glaciers or deserts, fine-grained, wind-blown material forms loess. Although silt makes up the majority of the material, there may also be trace amounts of sand and clay. Quartz is the predominant mineral found there, with trace amounts of feldspar, calcite, dolomite, and clay.


3. What is DTH bit?

Down-the-hole (DTH) hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a splined drive for rotating the bit in the ground.
