Product Description
Product Overview
High quality DTH drill bits and impactors designed for demanding applications in hard rock mining, quarrying, and tunneling operations.
DTH Drill Bit Types
Flat Type
Specifically engineered for drilling hard rock layers and highly corrosive rock 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
Combination design providing increased speed over conventional domed buttons while maintaining higher longevity than aggressive ballistic carbide designs.
Dome
Durable shape engineered for hard, abrasive rock and deep-hole drilling applications. Suitable for nearly all rock drilling operations.
Ballistic
Ideal for less-abrasive sedimentary deposits where drilling speed is critical. Not recommended for badly broken ground or extremely hard rock formations.
