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.

Another benefit of a long flexible drill bit extension is its length. These extensions can vary in length, but typically they are designed to reach depths that standard drill bits cannot. This is particularly useful when working on projects that require drilling through walls or reaching into tight spaces This is particularly useful when working on projects that require drilling through walls or reaching into tight spaceslong This is particularly useful when working on projects that require drilling through walls or reaching into tight spaces This is particularly useful when working on projects that require drilling through walls or reaching into tight spaceslonglong flexible drill bit extension. The added length of the extension allows you to drill deeper and further than you could with a regular drill bit.
