    Our threaded drill bits undergo multiple heat treatments and are meticulously machined using advanced CNC machines. This enhances their lifespan and wear resistance, enabling them to perform exceptionally well in extreme rock formations. We utilize premium-grade steel and high-quality tungsten alloys in the manufacturing process, providing the necessary toughness and strength to withstand high impact and pressure environments. Our bits not only offer efficient drilling capabilities but also excel in chip evacuation, maximizing their lifespan and impact strength. With various shank shapes, head designs, and tooth structures, our threaded drill bits can be tailored to meet the specific requirements of different rock formations and drilling depths.

    The versatility of our threaded drill bits makes them widely applicable across various industries, including open-pit mining, underground mining, tunneling, anchoring projects, blast furnace tapping, tunnel construction, hydroelectric projects, quarrying, and various other construction projects.

    How does a threaded button bit work?

    When the hammer piston strikes shank adapters, the generated shockwave will transmit through coupling sleeves, drill rods and finally reach the drill bit. The drill bit delivers the axial impact energy and performs continuous rotation at the same time. The combined effects of impact, crushing and shearing will break the rocks. The flushing medium flowing through drill rod center passes through drill bits and reaches the bottom hole. The medium will then carry rock cuttings out of the drilling hole to prepare the hole bottom for the next percussion cycle.

    Features
    • High-speed impact capability for faster drilling and efficient rock breaking.
    • High-performance design for increased drilling distance, enhancing drilling efficiency and productivity.
    • Customizable optimization based on different rock formations to ensure efficient drilling operations.
    • High-strength alloy steel bodies with special heat treatment processes, ensuring fracture rates below 0.5% and ensuring drilling safety.
    • CNC machining and alloy tooth assembly processes, resulting in tooth loss rates below 0.5%, improving drilling stability and reliability.
    Main components of a threaded button bit

    A threaded button bit mainly consists of alloy steel bit body, connectors, face buttons, gauge buttons, flushing holes, flushing grooves, bit face and bit skirt.

    How to choose a drill bit face

    Different bit faces bring changes to carbide button layout, bottom-hole contact pattern, and flushing channels. Common bit face types include flat face, drop center, convex face and concave face.

    You can choose a bit face based on these factors:

    • Rock hardness and abrasiveness
    • Whether the rock formation is competent or fractured
    • Required hole straightness
    • Drilling direction
    • Cuttings-removal conditions
    • Impact power of the rock drill
    • Bit diameter
