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.

The thread button bit, also known as a tap drill bit or a threading bit, is an essential component in the process of thread cutting. Its design incorporates a button-shaped projection at its end, which not only aids in the initial piercing of the material but also contributes to the accuracy and stability during the threading operation. The 'button' serves as a cutting edge, shearing off material as it rotates, gradually forming the required thread pattern.
