The Science Behind Button Bits: How Tungsten Carbide Tips Maximize Drilling Efficiency
When it comes to rock drilling, few components play a more critical role than Button Bits. These small yet powerful tools are the first point of contact with the rock—and their design, material, and shape directly influence your drilling speed, tool life, and cost-efficiency. At the heart of every high-performance Button Bit lies tungsten carbide—a material known for its exceptional hardness and wear resistance. But what makes these tiny tips so effective? Let’s dive into the science behind it. What Are Button Bits? Button Bits are drill bits used in mining, tunneling, and construction. They are typically made of steel bodies fitted with multiple tungsten carbide inserts (or "buttons") at the tip. These buttons come in various shapes—domed, ballistic, or semi-ballistic—each suited for specific rock types and drilling conditions. Why Tungsten Carbide? Tungsten carbide is a composite material made from tungsten and carbon, sintered together at extremely high temperat...
