DTH (down-the-hole) rock drilling tools are a type of rock drilling equipment that is designed to be used in very hard rock formations. These tools are typically used in mining and construction applications, and they are able to drill through rocks that are much harder than the rocks that can be drilled with traditional drills.
They are essential for many industrial and construction applications. If you need to drill through hard rocks, then DTH equipment is definitely something you should consider investing in.
