Product Description
140mm Convex Face Tungsten Carbide DTH Button Bits
DTH Drill Bit Types
- Flat Type: Ideal for hard rock layers and highly corrosive formations under high wind pressure conditions
- Convex Type: Optimized for soft to medium hard rocks with medium to low wind pressure, delivering faster drilling speeds
- Concave Type: Versatile design suitable for all rock layers, particularly effective in medium hard rocks with excellent drilling straightness and efficient slag removal
Carbide Button Designs
Semi-Ballistic: Advanced combination design offering increased drilling speed compared to conventional domed buttons while maintaining higher longevity than aggressive ballistic designs.
Dome: Durable shape engineered for hard, abrasive rock formations and deep-hole drilling applications. Suitable for nearly all rock drilling conditions.
Ballistic: Optimized for less-abrasive sedimentary deposits where drilling speed is critical. Not recommended for severely broken ground or extremely hard rock formations.
