Drill rods, usually constructed from high-strength steel, transmit the mechanical energy from the drill rig to the drill bit. They are designed to withstand the intense forces exerted during drilling and are available in various lengths to accommodate deep-hole drilling. The quality and condition of drill rods significantly impact drilling efficiency and overall project costs The quality and condition of drill rods significantly impact drilling efficiency and overall project costs

The process of using a thread drill bit is relatively simple. First, the material to be drilled must be clamped securely in place. Then, the thread drill bit is inserted into a drill press or hand drill and rotated at high speed. As the bit cuts into the material, it creates a helical groove that forms the threads. Once the desired depth and pitch of the threads have been achieved, the bit is removed and the threads are finished by tapping, which involves driving a tap into the threads to clean them up and ensure they are uniform Once the desired depth and pitch of the threads have been achieved, the bit is removed and the threads are finished by tapping, which involves driving a tap into the threads to clean them up and ensure they are uniform

As technology progressed, coal mine tools underwent a transformation. The introduction of pneumatic machines in the 19th century revolutionized coal extraction. Devices like the pneumatic pick, powered by compressed air, significantly increased the speed and efficiency of coal cutting. This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavations This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavations
