drilling through limestone is challenging.

The development of hard rock drilling bits has been a story of innovation and technological advancement. From the early days of simple pickaxes to the sophisticated tungsten carbide and polycrystalline diamond (PDC) bits used today, the evolution mirrors the progress of human engineering. The introduction of these advanced drilling bits has significantly increased drilling efficiency, reduced operational costs, and enhanced overall productivity.

A hard rock drill bit is essentially a piece of engineering brilliance, combining robust materials with intricate designs to create a tool that can efficiently fracture and remove hard, abrasive rocks. They are primarily classified into two categories fixed-cutter bits (also known as PDC or Polycrystalline Diamond Compact bits) and roller-cone bits. Each type has its unique advantages and is selected based on the specific drilling conditions and rock types encountered.
