Product Description
203mm Spline DTH Drill Button Bit Overview
DTH Drill Bit Types
DTH Drill Bits are categorized into three main types based on their design and application:
- Flat Type: Designed for drilling hard rock layers and highly corrosive rock formations under high air pressure conditions
- Convex Type: Optimized for soft to medium hard rocks with medium to low air pressure, delivering fast drilling speeds
- Concave Type: Suitable for all rock layers, particularly effective in medium hard rocks with excellent drilling straightness and efficient slag removal
Carbide Button Designs
SEMI-BALLISTIC
A hybrid design that combines the speed advantages of conventional domed buttons with the enhanced longevity of ballistic carbide configurations.
DOME
Robust shape engineered for hard, abrasive rock conditions 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 severely broken ground or extremely hard rock formations.
