A full-faced cross bit is a specialized rock drilling tool designed for percussive and rotary drilling applications, particularly in hard and abrasive rock formations. The bit features a cross-shaped, full-face cutting structure with tungsten carbide inserts, ensuring enhanced durability and drilling efficiency.
- Design: Full-faced cutting structure is a symmetrical cross shape covering the entire face of the bit for efficient rock penetration and provides balanced cutting action, reducing hole deviation and ensuring straight boreholes. Flat carbide tips are designed for extreme hardness and wear resistance in highly abrasive rock. Chisel-shaped carbide tips improve penetration rate and cutting efficiency. The bit includes air or water-flushing holes to efficiently remove rock cuttings and minimize overheating.
- Applications:
- Mining & Quarrying: Used in underground and surface mining for blasthole drilling; ideal for drilling in hard rock formations such as granite, basalt, and quartzite.
- Tunneling & Infrastructure Projects: Commonly used in rock bolting and anchor hole drilling; suitable for excavation and ground stabilization in tunnel construction.
- Geotechnical & Exploration Drilling: Provides accurate borehole formation in geological surveys and soil testing; ensures stable core sampling in mineral exploration.
- Water Well & Hydrogeological Drilling: Used in drilling hard rock layers for groundwater extraction; ensures straight and consistent boreholes for well casing installations.
- Foundation & Road Construction: Applied in slope stabilization, foundation support, and roadbed reinforcement; used in drilling for ground anchors and structural reinforcements.
- Materials: The bit body is made from high-strength, heat-treated alloy steel to withstand impact and stress. Tungsten carbide inserts provide superior wear resistance and maintain sharpness over extended drilling operations.
- Configurations: 1-1/4″ to 2″ bit diameter with R25 or R32 thread type.
