The tapered drill bit is a core rock-breaking component in drilling operations, connecting to the drill rod through a tapered interface for direct and efficient rock fragmentation. Known for its high drilling speed, strong wear resistance, and broad applicability, it is commonly available in chisel, cross, and button types. Among these, the button bit stands out for its exceptional performance across varied rock formations, excellent wear resistance, and smooth operation that reduces jamming risk. Crafted from high-grade carbide, it effectively transfers impact energy from the drill rig to the rock. Selecting the appropriate type based on specific rock conditions is essential to maximize drilling speed and optimize cost efficiency in mining and construction applications.

We utilize carefully selected domestic steel, heat-treated for optimal toughness, combined with premium-grade carbide buttons. This combination delivers exceptional hardness and wear resistance in challenging conditions.
Alloy bits are thermally inserted with precision. The inner bore features zinc-plating or is fitted with a copper bushing to ensure a secure fit, achieving more than 90% taper contact. This robust design withstands high-frequency impact, mitigating breakage and button loss.
Strategically designed dust vents and water ports ensure smooth slag removal and faster drilling progress. High dimensional precision guarantees a perfect fit with the drill rod, reducing the risk of dislodgement.
We recommend the optimal bit type based on specific rock formations, providing cost-effective designs tailored directly to operation requirements to help maximize project efficiency.
Crafted with high-grade carbide, this spherical button bit delivers exceptional wear resistance and low rotation resistance, making it the ideal solution for highly abrasive and corrosive hard rock formations.
Engineered for superior penetration and balanced durability, it achieves fast drilling progress in medium-hard rock with moderate corrosiveness. The design combines efficient cutting with reliable wear resistance.
Designed for maximum penetration force and high drilling speed, the conical button bit excels in non-corrosive formations. Its geometry makes it particularly suitable for small-diameter applications.
Specialized for rapid advancement in soft rock conditions, the ballistic button bit delivers smooth progress in non-corrosive ground, minimizing resistance while maintaining consistent performance.
Round steel is selected and cut to specific sizes to form the initial blank.
The blank is heated and forged under high pressure to create the basic shape and dense internal structure.
The forged blank undergoes initial turning to achieve basic dimensional accuracy for further processing.
The bit body undergoes controlled heating and cooling to enhance hardness, toughness, and wear resistance.
Precise holes for alloy buttons are drilled, and dimensions verified to ensure a proper fit.
Key features are machined: flushing holes are drilled, splines milled, and slag discharge slots created.
Hardened alloy buttons are securely embedded into the pre-drilled holes using thermal or press-fit methods.
The product is precision-turned and surface-treated for corrosion resistance and a professional finish.
Finished bits are packaged securely to ensure protection during storage and shipment.
