A carbide-tipped cross bit is a type of rock drilling bit characterized by a cross-shaped cutting structure with tungsten carbide inserts. It is primarily used for percussive drilling in hard and abrasive rock formations. These bits are highly durable and designed for straight hole drilling, making them a common choice in mining, tunneling, and construction.
- Design: Cross-shaped cutting structure provides a balanced cutting action and improved hole straightness and reduces bit deviation in fractured or jointed rock formations. Chisel-Edged Carbide is used for efficient cutting in hard rock. Wedge-Shaped Carbide is designed for improved penetration in medium-hard formations. Integrated air or water-flushing system for effective cuttings removal and reduced bit wear. Compatible with drill rods and shank adapters (e.g., R25, R28, R32) for easy integration with drilling systems.
- Applications: Carbide cross bits are ideal for drilling in tough conditions where high impact resistance and hole precision are required.
- Mining & Quarrying: Used for blasthole drilling in underground and open-pit mining; Effective in hard rock formations such as granite, basalt, and quartzite.
- Tunneling & Construction: Used in rock bolting, ground stabilization, and excavation projects. Ensures precise hole drilling in foundation works and infrastructure projects.
- Geotechnical & Exploration Drilling: Provides stable hole formation in soil testing and rock sampling applications. Used in drilling for geological surveys and mineral exploration.
- Hydrogeological & Water Well Drilling: Suitable for drilling through hard rock layers to access groundwater. Ensures straight and efficient borehole formation for well construction.
- Road & Railway Construction: Utilized in slope stabilization, rock anchoring, and drilling for foundation support.
- Materials: Bit Body is made of heat-treated alloy steel to withstand high impact and stress. Cutting Edges are tungsten carbide inserts brazed onto the cross-shaped head for enhanced wear resistance.
- Configurations: Bit Diameter: 1-1/2″ to 5″, Thread Type: D Thread, H Thread, R25 to R38, T38 to T51.
