A shallow carbide cross bit is a type of rock drilling bit featuring a low-profile, cross-shaped cutting structure with tungsten carbide inserts. It is specifically designed for soft to medium-hard rock formations, where faster penetration rates and reduced resistance are required.
- Design: The shallow cross design has a lower-profile cutting face which reduces resistance, allowing for higher drilling speeds with optimized carbide tip angles that improve cutting efficiency while maintaining hole straightness. The bit has air or water-flushing holes remove debris, preventing clogging and reducing overheating.
- Applications:
- Mining & Quarrying: Used for drilling in soft to medium-hard rock, such as limestone and shale; applied in surface drilling and short blasthole drilling operations.
- Geotechnical & Exploration Drilling: Suitable for soil investigation and rock sampling in less abrasive formations and is used in shallow core drilling applications.
- Construction & Tunneling: Used in rock bolting and ground support drilling in tunnel and infrastructure projects and is effective in foundation drilling for shallow-depth applications.
- Water Well & Hydrogeological Drilling: Ideal for drilling through consolidated soil and soft rock layers in groundwater exploration and is used for shallow well and borehole drilling in sedimentary formations.
- Road & Railway Construction: Applied in slope stabilization and anchoring in road and rail infrastructure and ensures quick and efficient drilling for temporary support structures.
- Materials: The bit body is made from heat-treated alloy steel to withstand impact forces and resist wear. The cutting inserts are tungsten carbide tips ensure durability and extended bit life.
- Configurations: 1-1/2″ to 2″ bit diameter with H-Thread.
