The hardness of limestone can vary greatly, from relatively soft to extremely hard, depending on factors such as its mineral content and degree of compaction. Soft limestones can be easily drilled using standard drilling equipment, but harder varieties often necessitate more robust machinery and specialized bits. Carbide-tipped drill bits, for instance, are commonly employed due to their durability and ability to withstand the abrasive nature of limestone.

Performance metrics such as impact energy, rotation speed, and feed force are critical determinants of a drill’s efficacy. High-impact energy ensures that the tool can break through hard rock effectively, while a variable rotation speed allows operators to adapt to different drilling conditions. The feed force determines how much pressure the drill can apply to the rock face, affecting penetration rates and drill bit longevity.
