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.

  • The rod drilling machine works by clamping the rod in place and then using a drill bit to remove material from the rod's surface. The machine can be adjusted to drill holes of various sizes and depths, making it a versatile tool for a wide range of applications.
