The global demand for high-performance rock drilling equipment, specifically AirLegDrills, has seen a significant surge in recent years. As industrialization expands in emerging markets and infrastructure projects become more complex, the role of pneumatic drilling technology remains irreplaceable. Air-leg rock drills, such as the widely recognized YT27 and YT28 models, are pivotal in underground mining, tunneling, and quarrying operations across the globe.
Currently, the market is characterized by a drive toward efficiency and durability. In regions like South America (Peru, Chile), Africa (South Africa, Ghana), and Southeast Asia (Indonesia, Vietnam), the mining industry relies heavily on air-leg drills for their portability and powerful impact energy. These tools are essential for drilling medium-hard to hard rock (f=8-18), where hydraulic rigs might be too bulky or cost-prohibitive for the specific geology.
The modern era of rock drilling is dominated by advancements in metallurgy. Tungsten Carbide Button Bits and high-strength alloy steel rods are now standard. Factories are utilizing vacuum heat treatment processes to ensure that shank adapters and drill rods can withstand the extreme stress of high-frequency impacts without premature failure.
While the air-leg drill is manually operated, the manufacturing of its components (like the HC110 shank adapter or PDC core bits) has shifted to AI-driven CNC machining. This ensures micron-level precision, leading to better thread compatibility and reduced energy loss during power transmission.
With labor safety coming to the forefront globally, manufacturers are focusing on vibration damping and improved leg-telescoping mechanisms to reduce operator fatigue. This "human-centric" design is a major selling point in the current global procurement landscape.
We have more than 40 years of drilling tool manufacturing experience. All this expertise is built into all our rock drilling tools - for your benefit.
We look for outstanding performance in all our products and services. Ultimately, that means excellent hole quality and low-cost drilling for you.
We are one of the professional rock drilling tool manufacturers in China. Our state-of-the-art products will also give you a leading edge.
We offer tophammer and DTH equipment for every application: underground mining, tunneling, surface mining, and quarries.
When searching for a China AirLegDrill pricelist, global buyers are looking for more than just low costs—they are looking for value. As a leading manufacturer in Shandong, we provide several distinct advantages that set us apart in the international market:
By leveraging China's robust industrial supply chain, we procure high-grade raw materials at competitive rates. This allows us to offer YT27 jack hammers and DTH hammers at prices significantly lower than European or American counterparts without compromising on the f=8-18 rock hardness performance.
Our facility houses over 500 types of rock drilling tools. Whether you need 10 units for a local project or 1,000 units for a national mining contract, our lead times remain consistent and reliable.
Global procurement often requires localized adaptations. We can customize thread types (R22, R25, R32, T38) and bit designs based on the specific geological reports provided by our clients.

Understanding where and how our tools are used is crucial for providing the right "Quotes & Pricelist." Our products are engineered for versatility across various terrains:
The YT24/YT28 Air-Leg Drills are the workhorses of narrow-vein mining. Their ability to drill horizontal or inclined holes makes them perfect for blast-hole preparation in gold and copper mines.
In railway and highway tunneling, our self-drilling anchor systems and tapered drill rods provide the stability needed for rock bolting and ground support in unstable soil conditions.
For granite and marble extraction, the precision of our diamond multi-wire saws and YN27J internal combustion drills ensures minimal waste and clean cuts, maximizing the value of the extracted stone.
SHANDONG KAT DRILLING TOOLS is one of the most professional manufacturers of Rock drilling Tools in China. In terms of overall strength, it takes the lead among enterprises of the same industry in China. The company mainly produces over 500 kinds of products such as rock drilling tools, mining tools and drilling tools.
Our commitment to quality is backed by rigorous ISO certifications and a legacy of over four decades. We don't just sell tools; we provide solutions that enhance the efficiency of your drilling operations, ensuring a lower cost per meter drilled.
The YT27 Pneumatic Air Leg Rock Drill, featured prominently in our 2024 pricelist, represents the pinnacle of manual pneumatic technology. With a weight of approximately 27kg, it strikes a perfect balance between power and portability. It is designed for drilling downward or inclined blast holes in medium-hard rock.
Technical Superiority: The air-water linkage system ensures that the drill only operates when the flushing water is flowing, preventing dry drilling which can lead to dust inhalation and premature bit wear. Our China factory uses high-frequency quenching for the piston and pawl parts, ensuring a service life that exceeds 500 drilling hours under standard conditions.
A drilling system is only as strong as its weakest link. This is why our HC110 Shank Adapters are manufactured using premium 20CrNi2Mo or 35CrNiMoV alloy steel. The role of the shank adapter is to transmit impact energy from the piston to the drill rod. Any misalignment or material weakness leads to energy loss. By choosing our precision-engineered adapters, users report up to a 15% increase in drilling penetration rates.
Our St58 and R32 button bits utilize YK05 grade tungsten carbide tips. These tips are press-fitted into the bit body using a cold-insertion technique that prevents thermal stress. Whether it's a spherical, ballistic, or conical button shape, our bits are designed to fracture rock more efficiently, requiring less torque from the drill motor. This reduces the wear on your expensive air leg drill and extends the life of your tapered drill rods.
Modern procurement officers in the mining sector are no longer just looking at the "Sticker Price." They are calculating the TCO (Total Cost of Ownership). This includes the cost of the tool, the lifespan of the wear parts (like shank adapters and couplings), and the fuel/energy efficiency of the operation. Our Pricelist is structured to provide bulk-buying incentives that lower the TCO significantly for large-scale operations.
The industry is moving toward "Mist Lubrication" systems which reduce oil mist in the air, making underground environments safer for workers. Additionally, the development of the YN27J internal combustion rock drill has revolutionized remote operations where air compressors are impossible to transport. It is a self-contained unit that performs drilling, breaking, and tamping without external power sources.
As a leading China AirLegDrill factory, we are committed to these trends, investing 5% of our annual revenue back into R&D. Our mission is to keep your projects on schedule and under budget with the world's most reliable rock drilling tools.
