The S250 air leg rock drill stands as a global benchmark for rugged reliability in demanding worksites. Engineered for high-speed drilling in hard and medium rock, it delivers 2200 blows per minute even at moderate air pressure, ensuring fast penetration and consistent productivity. Its three configurations—jackleg, stoper, and sinker—adapt seamlessly to mining, tunneling, railway, and water conservancy projects. Whether drilling horizontal, inclined, or vertical blast holes, this pneumatic powerhouse handles confined spaces and complex orientations with ease.
Crafted from premium alloy steel, the S250 boasts exceptional durability that minimizes downtime and maintenance costs. Its forged components and removable bushing protect the drill head from wear, while the integrated air leg with 762mm extension provides stable thrust for precise operations. Designed with operators in mind, it features ergonomic controls, vibration-dampening handles, and optional muffler to reduce noise. The simplified structure with fewer parts makes servicing straightforward, even in remote job sites.
With a balanced power-to-weight ratio, the S250 combines robust performance with manageable handling—weighing 39kg with its air leg. It consumes 4.4 m³/min of air and accommodates 22mm hex drill steel, compatible with common button bits for versatile use. Wet drilling capability suppresses dust, enhancing worksite safety. Backed by ISO 9001 and CE certifications, each unit undergoes strict testing before shipment, offering a one-year warranty for peace of mind. It’s the trusted choice for contractors seeking long-lasting, cost-effective drilling solutions.
Downtime can significantly impact quarry profitability. The S250 is designed for easy maintenance, allowing quick access to key components and reducing service time.
As a result, quarry operators can sustain high daily output while minimizing interruptions to drilling schedules.
Developed by our professional rock drilling machinery factory with over 15 years of industry expertise, the S250 is a hydraulic surface rock drill engineered specifically for demanding quarry and open-pit mining environments. Unlike conventional air-leg rock drills that rely on compressed air, this machine integrates a high-torque hydraulic system to deliver consistent power across various rock formations—from limestone to granite with a uniaxial compressive strength of up to 250 MPa. Its core components, including the carbide-tipped drill bit and shock-absorbing mechanism, are precision-manufactured in our in-house forging and heat treatment workshops, ensuring durability even in 24/7 operation cycles.
