When wielding a 75mm drill bit, one must exercise caution and respect its power. It's imperative to use a steady hand or secure the workpiece to prevent accidents. The right choice of drilling speed is crucial; too fast and you risk overheating the bit, too slow and you might compromise the hole’s integrity. The proper application of lubricant can also mean the difference between a clean hole and a catastrophic slip, especially when dealing with tougher materials.

Another challenge is the presence of natural fractures and cavities within the limestone. These can lead to instability during drilling, potentially causing borehole collapse or drilling deviation. To address this, engineers use techniques like underreaming or casing to reinforce the hole and maintain stability. Additionally, detailed geological surveys are conducted before drilling to identify and map these features, allowing for strategic planning Additionally, detailed geological surveys are conducted before drilling to identify and map these features, allowing for strategic planning Additionally, detailed geological surveys are conducted before drilling to identify and map these features, allowing for strategic planning Additionally, detailed geological surveys are conducted before drilling to identify and map these features, allowing for strategic planningdrilling through limestone.
