Down-the-hole (DTH) hammer drilling is a method of rock drilling that uses a pneumatic hammer to pulverize the rock at the bottom of the hole. This technique allows for faster and more efficient drilling in various types of rock formations, making it a popular choice for mining, construction, and.

Down-the-hole (DTH) hammer drilling is often used to drill large, deep holes in hard rock formations or concrete. It is, as the name tries to explain, a hammer drill which is positioned down there in the hole. It is as effective as handheld hammer drilling machines which are widely spread.

Down-the-hole drilling is to drive the hammer behind the drill bit by compressed air by means of the drill pipe. The piston strikes a little bit straight, while the hammer external cylinder provides direct as well as steady guidance of the drill a little bit. This makes the effect of power not lost.

Downhole hammer drilling was developed in 1951, it is a method that is carried out when a hammer hits directly in the mouth of the bottom of the hole, in this way, the loss of energy transmitted by the percussion of the piston is avoided. Through the linkage, since from 15 to 20 meters, the top.
