Extension Rod – Reliable Drill Rod for Efficient Rock Drilling

Extension rods are a critical type of drill rod used to extend drilling depth while maintaining stable energy transmission from the drilling machine to the drill bit. In rock drilling applications, extension rods are widely used in surface mining, quarrying, and construction projects where consistent hole alignment and drilling efficiency are required.

As professional rock drill rods, extension rods are designed to withstand repeated impact and torsional loads, ensuring reliable performance in hard and abrasive rock conditions.
