FAQ:
1. What is DTH hammer?
Down-the-hole drilling (DTH) essentially involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation and air. These active elements combine to be efficient at crushing rock.
2. What is the hardest rock to drill?
Diamond is the hardest (readily available) naturally occurring substance in the world, and so finds itself an invaluable material in the process of drilling through extremely strong rocks such as granite and basalt.
3. Should I use water when drilling rocks?
Using water keeps both the drill bits and the rock cool while drilling. This will help to extend the life of diamond-tipped bits. It will also prevent the rock that you're drilling holes in from cracking due to heat expansion.
