Button bits are specialized drilling tools used for high-performance rock penetration in mining, construction, and geotechnical applications. These bits are designed to withstand extreme impact and abrasion while delivering efficient drilling in hard rock formations.
- Design: Spherical Buttons: Used for hard rock drilling, offering high impact resistance. Ballistic Buttons: Designed for faster penetration in medium-hard rock formations. Conical or Parabolic Buttons: A balance between penetration rate and durability, suitable for mixed formations. Flushing System: Equipped with air or water-flushing holes to remove cuttings and reduce bit wear. Threaded Connection: Designed with standard thread types (e.g., T38, T45, T51) for compatibility with drill rods and shank adapters.
- Applications:
- Mining & Quarrying: Used in surface and underground drilling operations for blasthole drilling; Efficient in hard rock formations, including granite and basalt.
- Tunneling & Construction: Applied in rock bolting, foundation drilling, and excavation projects; Essential for infrastructure projects requiring deep rock penetration.
- Geotechnical & Exploration Drilling: Used in core drilling and soil stabilization projects; Provides accurate and stable borehole formations in tough ground conditions.
- Oil & Gas Drilling: Utilized in pre-drilling operations before deep drilling with tricone or PDC bits; Helps in drilling hard cap rock layers in petroleum exploration.
- Hydrogeological & Water Well Drilling: Efficient in drilling through consolidated rock formations to access groundwater sources.
- Materials:Body: Made of high-strength, heat-treated alloy steel to withstand high impact forces. Cutting Tips: Tungsten carbide buttons are brazed or press-fitted into the bit to provide superior hardness and wear resistance.
- Configurations:Bit diameters: 1-1/4″ to 8″, Thread Types: H Thread, R25 to R51, T38 to T51.
