Next, the drilling equipment must be properly set up and calibrated. This involves ensuring that the drill bit is positioned at the correct angle and depth, and that the drilling parameters (such as rotation speed and feed rate) are optimized for the specific limestone being drilled. It is also important to use a lubricant or cooling fluid to reduce friction and prevent overheating of the drill bit It is also important to use a lubricant or cooling fluid to reduce friction and prevent overheating of the drill bit It is also important to use a lubricant or cooling fluid to reduce friction and prevent overheating of the drill bit It is also important to use a lubricant or cooling fluid to reduce friction and prevent overheating of the drill bitdrilling through limestone.

The choice of drill rod steel is crucial due to the harsh conditions it encounters. It needs to be strong enough to resist bending and breaking under immense pressure, while also being resilient against wear and tear caused by friction and abrasive materials. Typically, drill rod steel is composed of high-carbon alloy steels, often containing elements like manganese, chromium, and nickel to enhance strength, toughness, and resistance to corrosion.
