Center drill bits typically come in two main types - the No. 0 and No. 1 sizes, with the No. 0 being smaller and more suited for starting holes for tapping threads, while the No. 1 is larger and ideal for creating centers for lathe work. They have a distinctive conical shape, with a 60-degree included angle that allows them to create a V-shaped indentation, guiding the larger drill bit or lathe cutting tool into perfect alignment.

The drill bit, often made of tungsten carbide or steel, is the cutting edge of the tool. It comes in different designs such as button bits, DTH (Down-The-Hole) bits, and PDC (Polycrystalline Diamond Compact) bits, each suited for specific rock types and drilling conditions. Button bits, for instance, are widely used in surface drilling due to their durability and ability to handle softer rocks. On the other hand, PDC bits are ideal for drilling through extremely hard rocks due to their exceptional wear resistance.

  • The advent of high-strength, low-alloy (HSLA) steels brought about a significant leap in performance. These alloys offered improved resistance to corrosion, higher yield strength, and better toughness, allowing drill rods to withstand the rigors of deep drilling without failing. Furthermore, heat treatment processes were refined to give the steel additional hardness while retaining its flexibility, ensuring that the rods could bend without breaking as they navigated through twists and turns in the mine shaft.
