Our technology is the final result of a continuous research focused to the working processes optimization. In our Bari-Modugno plant there are 2 Thompson friction machines and several CNC machine tools that allow us to obtain all the components of the final product through a sequence of predefined manufacturing steps.
Our challenge is the constant attention to the quality of the products, starting from raw material purchasing. In order to avoid any discontinuity of our production processes we have a furnace for the heat treatment of the tool joints and the different part of DTH hammers.
Therefore our technology is strongly supported by the human capabilities of Colli family, that boasts more than 45 working years in the drilling field.
