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 temperatures. The result is one of the hardest materials used in industrial applications—second only to diamond.

Here’s why it’s perfect for Button Bits:

• Extreme Hardness: Cuts through hard rock without deforming.
• High Wear Resistance: Maintains its shape and sharpness for longer.
• Thermal Stability: Performs under high temperatures generated during deep drilling.
• Fracture Toughness: Resists cracking even under repeated impact.
• 
  

How It Maximizes Drilling Efficiency

The tungsten carbide buttons deliver concentrated impact energy directly into the rock, fracturing it efficiently while minimizing energy loss. This results in:

• Faster penetration rates
• Reduced fuel and air consumption
• Fewer bit replacements
• Lower operational downtime

Whether you’re using Button Bits for Jackhammers or heavy-duty rigs, the advantage of tungsten carbide translates into better performance and lower cost per meter drilled.
