Audited Supplier Drifting and tunnelling tools include rods, shank adapters, couplings and bits.
We have mainly 9 threads: R22,R25, SR25,R28,SR28,R32,SR32,SR35, and R35.
Diameter: 38-127mm,They can be used with button bits, cross bits and reaming products.
Button bits, also known as button drill bits, are an important type of drill bit commonly used in various drilling operations. They are widely applied in fields such as mining, construction, and tunneling.
The main features and advantages of KAT button bits include:
*Excellent wear resistance: Typically made from high-quality materials like tungsten carbide, they can withstand the rigors of drilling through hard rocks and abrasive materials, ensuring a long service life.
*Efficient drilling performance: Designed to provide high penetration rates, which helps to increase productivity in drilling operations.
*Versatility: Can be used in a wide range of rock types and drilling conditions, making them suitable for different applications.
*Different shapes and designs: Available in various shapes, such as spherical, ballistic, and conical, to meet specific drilling requirements. For example, spherical button bits are suitable for most rock types, while conical ones might be preferred in certain situations.
*Threaded connection: Many button bits have a threaded design for easy attachment and detachment from the drilling equipment.
In summary, button bits are essential tools in the drilling industry, offering durability, efficiency, and adaptability for drilling through different materials and in various working environments. Their performance and characteristics make them a popular choice for many drilling projects.
