Hengshui Jrain Frp drilling through limestone is challenging.

The 20th century saw further advancements in drill bit technology. The introduction of tungsten carbide and diamond-tipped drill bits revolutionized the industry by providing much longer wear life and allowing for drilling in harder materials such as steel and concrete. Additionally, the development of rotary drilling rigs and hydraulic hammers made it possible to drill deeper and more precise holes than ever before.

The advent of high-strength, low-alloy (HSLA) steels brought about a significant leap in performance. These alloys offered improved resistance to corrosion, higher yield strength, and better toughness, allowing drill rods to withstand the rigors of deep drilling without failing. Furthermore, heat treatment processes were refined to give the steel additional hardness while retaining its flexibility, ensuring that the rods could bend without breaking as they navigated through twists and turns in the mine shaft.
