Fiberglass, or glass-reinforced plastic, is a composite material made from fine fibers of glass embedded in a polymer matrix, typically epoxy or polyester resin. When mixed with sand, it forms a composite that enhances the strength and stability of the pipe. The sand acts as a reinforcing agent, augmenting the pipe's structural integrity, making it ideal for high-pressure applications and environments with abrasive substances.

One of the most significant advantages of using an extension drill rod is its ability to reach deep, narrow, or awkwardly positioned drill points. In construction sites where beams, joists, or metal frameworks require precise hole placement, the rod's elongated design facilitates accurate drilling without compromising safety or accuracy. Additionally, it proves invaluable in situations where obstacles prevent a drill from aligning directly with the work surface, such as when fitting screws into pre-existing structures or working within confined interior spaces.
