Open-pit mines require drills that work efficiently on bench surfaces where angles and drilling positions change frequently. The S250 pneumatic rock drill adapts easily due to its balanced air-leg structure and convenient angle adjustment.

From iron ore benches to coal strip mines, the S250 ensures consistent penetration and precise hole spacing, which directly improves blasting uniformity and fragmentation size — reducing secondary crushing costs.

This operational superiority stems from the S250's core engineering. The drill features a reinforced, yet lightweight, cylinder that delivers a higher impact frequency without a corresponding increase in air pressure demand. This means each strike is both powerful and efficient, maintaining a fast drilling rate even as bit wear progresses throughout the shift. The true advantage on a variable bench, however, lies in its patented swivel connector. This allows operators to seamlessly lock the drill at any angle from vertical to horizontal with a simple, one-handed adjustment. There's no need for cumbersome tools or time-consuming re-positioning, enabling crews to swiftly move from one blast hole to the next with unwavering positional accuracy.

Durability is built into every component to withstand the relentless abrasive dust and vibration of open-pit environments. The S250's internal mechanism is sealed against contaminants, dramatically extending service intervals and protecting critical parts from premature failure. This rugged design translates into lower lifetime operating costs and greater asset availability. For mine planners, the consistent performance of the S250 is a game-changer. By producing a uniform pattern of deep, clean holes, it ensures a well-controlled blast that yields optimally sized material. This efficiency ripples through the entire production chain, leading to faster loading times, less strain on primary crushers, and a significant boost in overall mineral throughput. The S250 doesn't just drill holes; it refines the entire excavation process.
