FAQ:
1. What is top hammer?
In top hammer drilling, the activity is concentrated at the top of the drill string, above the hole, as a hammer transmits cyclical shock waves to the drill bit by applying a percussive force on the drill rods or tubes (With DTH drills, the hammer is placed down-the-hole at the bit)
2. 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.
3. What is percussion drilling method?
Percussion drilling is the manual drilling technique that was used in the first well drilled. In this drilling technique, a hammering bit is attached to a long cable that is then lowered into a wide open hole.
