Description of Down the hole drilling|rotary|diamond hammer

Withdown the hole hammer drilling, the drill principIce Machine le consists of a combination of percussion and rotation. Unlike the top hammer, here the hammer drill is located directly in the borehole. These devices, known as 'down-the-hole hammers', are connected to the rotating drill pipes.
