Hengshui Jrain Frp drilling through limestone is challenging.

The design of rock drill extension rods is meticulous, with attention paid to factors such as tensile strength, fatigue resistance, and wear resistance. They are often heat-treated and precisely machined to ensure smooth threading, reducing the chances of damage during assembly and disassembly. The robust construction not only enhances the lifespan of the drill but also minimizes downtime due to repairs or replacements.
