Down-the-Hole Drill Machines are mainly used for perforation working during stone quarrying. For drilling the holes of introducing the diamond wire.

KEENTOOL Serious Down-The-Hole Drilling Machines are made up essentially of an electric motor connected to a rotating system.

The Down-The-Hole Drill Machine is generally able to move along two steel bars that act as a guide; The movement of Down-The-Hole Drill Machine is created by an oil-pressure system that guarantees the necessary thrust for the advancement of the head during the perforation.

The whole structure is positioned on site and anchored to the rock by a series of chains and hooks. Down-The-Hole Drill Machines work by destroying the nucleus. Another type of drilling machine is the so-called down-the-hole hammer; It is a rotary percussion machine that operates at the bottom of the hole while advancing.

Down-The-Hole Drill Machines commonly used for drilling use a pneumatic system: The energy thrust is transmitted by compressed air. In fact Down-The-Hole Drill Machines need air compressors. The pneumatic hammers penetrate the rock mass by means of a drill rod that is nothing more than a shaped steel rod. The pneumatic system is supported or sometimes substituted by the hydraulic system in which hydraulic oil instead of air is used to transmit the energy.
