DTH Button Bits and Hammers for Rock Drilling - 90-508mm Diameter Range with 0.8-2.4 MPa Pressure
Professional down-the-hole drilling tools designed for efficient rock drilling in various geological conditions.
Our DTH drill bits are categorized into three main types based on design and application:
Ideal for drilling hard rock layers and highly corrosive rock formations under high wind pressure conditions.
Optimized for soft to medium hard rocks with medium to low wind pressure, delivering faster drilling speeds.
Versatile design suitable for all rock layers, particularly effective in medium hard rocks with excellent drilling straightness and efficient slag removal.
Combination design providing increased speed over conventional domed buttons while maintaining higher longevity than aggressive ballistic carbide designs.
Tough shape engineered for hard, abrasive rock and deep-hole drilling applications. Suitable for nearly all rock drilling operations.
Ideal for less-abrasive sedimentary deposits where drilling speed is critical. Not recommended for badly broken ground or extremely hard rock formations.
