An all-steel cross bit is a durable and cost-effective rock drilling tool designed for percussive drilling in soft to medium-hard formations. Unlike carbide-tipped cross bits, all-steel cross bits are manufactured entirely from high-strength steel, making them suitable for applications where extreme wear resistance is not required.
- Design: The cross configuration provides a balanced cutting action for straight hole drilling and ensures even wear distribution and prolongs bit life. Machined steel edges provide effective rock-breaking capability in softer formations and can be resharpened multiple times, reducing operational costs. They are equipped with air or water-flushing holes to clear cuttings and prevent overheating.
- Applications: All-steel cross bits are ideal for low-cost, moderate-performance drilling where carbide bits are not necessary.
- Mining & Quarrying: Used for drilling in soft to medium-hard rock, such as limestone and sandstone; suitable for short blasthole drilling in surface and underground operations.
- Geotechnical & Exploration Drilling: Applied in soil investigation and shallow-depth drilling where high wear resistance is not needed; effective in preliminary drilling for mineral exploration.
- Construction & Tunneling: Used in ground stabilization and rock bolting for tunnels and infrastructure projects; ideal for foundation drilling in softer geological conditions.
- Water Well & Hydrogeological Drilling: Suitable for shallow borehole drilling in sedimentary formations; commonly used for drilling through soil and weak rock layers in well construction.
- Road & Railway Construction: Used for slope stabilization and anchoring in infrastructure projects; provides an affordable option for temporary support drilling.
- Materials: The bit body is made from heat-treated alloy steel to withstand impact forces and resist wear. Cutting Inserts are tungsten carbide tips ensure durability and extended bit life.
- Configurations: 1″ to 4″ with H-Thread, D-Thread or E-Thread
