Drill rods made of hardened steel are used for crafting tools for drilling projects. They are added to horizontal directional drilling projects as needed. Proper drill rod care and maintenance will extend the life of the material.

Of course, selection of the length of a drill rod is very important. The drill rod length may depend on the capabilities of the drilling equipment and other factors. In all, the factors of choosing the correct drill rods are steel grade, diameter and length.
