The drill motor, or hammer, is the powerhouse of the rock drill. It generates the force needed to drive the bit into the rock. In percussive drilling, this force combines rotary motion with a pulsating action, enhancing the drilling efficiency In percussive drilling, this force combines rotary motion with a pulsating action, enhancing the drilling efficiency In percussive drilling, this force combines rotary motion with a pulsating action, enhancing the drilling efficiency In percussive drilling, this force combines rotary motion with a pulsating action, enhancing the drilling efficiencyrock drill parts.

The primary advantage of using an extension rod lies in its ability to extend the drilling depth without compromising on the torque and power transmission. This is particularly crucial in deep excavation projects, tunneling, and large-scale construction works where reaching substantial depths is a necessity. The extension rods allow drillers to penetrate further into the earth's crust, facilitating the extraction of minerals, installation of anchoring systems, or creation of underground infrastructure.
