The drill bits produced by YS STEEL manufacturers feature anti-impact teeth, anti-crack bodies, smooth slag discharge, and high drilling speed. They cover mainstream thread specifications such as R32, R38, T38, T45, and T51, with a hole diameter range of 41-115mm. The tooth arrangement and water hole structure can be customized according to the geological conditions.
This model of Drill bit is the core rock-breaking component of the top-hammer rock drilling system, which receives the impact and torque transmitted from the drill pipe to complete the rock fragmentation.
1. For open-pit mining blasting holes, it is suitable for hard rock formations such as granite, ensuring excavation efficiency and reducing the frequency of drill bit replacement.
2. For underground mine tunnel excavation and blast hole construction, it is compatible with the narrow working conditions in the underground environment.
3. For stone material mining blasting holes, it handles strong abrasive rocks.
4. For road and railway tunnel excavation, and blasting hole construction in water conservancy and hydropower geotechnical projects.
It is targeted at original equipment manufacturers of rock drilling equipment, large-scale batch purchases by mining projects, on-site spare parts replenishment, and cross-border rock drilling tool wholesalers. It provides services to global mining enterprises, engineering contractors, and rock drilling tool traders.
Balanced hardness and toughness, less likely to chip when impacting hard rocks, effectively increasing the total drilling volume.
High strength, wear-resistant, does not crack or chip during long-term operation, longer service life.
The teeth are closely attached, resistant to vibration and anti-loosening, eliminating the premature failure of the drill bit.
Accurate engagement, low transmission loss, stable drilling, and reduced wear on the thread.

・ SoutheastAsia Openpit HardRock Mining Project (2025): 106 tons of T38 / T45 button bits were supplied to mining operators in Malaysia and Indonesia for granite openpit blasthole drilling. Stable drilling footage and low buttonchipping rate secured a longterm bulk supply framework.
・ MiddleEast Tunnel & Quarry Project (2025): 89 tons of R38 / T51 threaded bits were delivered to engineering contractors in Saudi Arabia and Oman for tunnel tunneling and quarry drilling. Reliable performance in complex abrasive rock with stable leadtime drives growing repeatorder volume.
・ African MiningTool Trading Project (2024): 72 tons of multsize tungstencarbide bits were provided for tool traders in Zambia as costeffective alternatives to imported drilling tools, lowering overall mining drilling cost and triggering followon purchase orders.
