Rwanda has positioned itself as an emerging mining hub in East Africa. Under the supervision of the Rwanda Mines, Petroleum and Gas Board (RMB), the country is actively transitionary from artisanal hand-tools to semi-mechanized and fully mechanized operations. Major minerals such as Tantalum (Coltan), Tin (Cassiterite), Tungsten (Wolfram), and Gold drive the primary export economy, alongside large infrastructure undertakings such as the Bugesera International Airport and the expansion of the national road grid.
However, the geological nature of the Kibaran Mobile Belt in Rwanda features deep valleys, steep slopes, and complex metamorphic rocks consisting of granites, pegmatites, and quartz veins. Excavation in such tough rock formations requires robust and versatile equipment. Hand-held, air-leg pneumatic drills have emerged as the standard solution due to their portability on mountainous terrain and operational efficiency in narrow-vein underground extraction.

Our pneumatic air-leg rock drills use an optimized valving system that ensures high impact frequencies. By refining piston geometry and implementing precise tolerances, we achieve maximum blow energy transmission to the rock face, reducing energy losses by up to 15%.
Working in underground mines in Rwanda means exposure to acidic groundwater. We construct our pneumatic cylinders, frontheads, and chuck sleeves from advanced heat-treated alloy steel (20CrNiMo), featuring hard chrome plating for high resistance to wear and rust.
The telescopic air-legs (like FT160A or FT160B) provide stable thrust and balance, reducing operator fatigue. Single-switch control handles combine throttle, water flushing, and air-leg feed control for smooth operation and safety on steep mine slopes.
Our tools are engineered to replace legacy systems with higher efficiency, matching or exceeding international specs. Check out our standardized ranges:
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 you tophammer equipment and DTH equipment for every application, such as underground mining and tunneling, surface mining, well drilling, quarries, and road construction.
Operating as a primary supplier from Shandong, China, our manufacturing facilities integrate Factory 4.0 paradigms, including automated heat treatment furnaces, high-precision CNC grinding machinery, and robot-assisted welding platforms. This allows us to guarantee perfect dimensions and microstructural uniformity for every piston, cylinder, and valve chest.
For procurement managers in Kigali, Rutongo, Musha, and beyond, this translates into stable pricing, robust bulk supply capacity, and standardized quality. By utilizing direct shipping lines from Chinese major ports to East African sea hubs like Dar es Salaam and Mombasa, followed by prompt transit through the Northern and Central corridors to Rwanda, we minimize transit delays and keep your mining projects fully stocked with replacement spares.
All air-leg drills manufactured for the Rwandan market support optimized wet-drilling ports. This injects pressurized water through the center of the hex drill steel, suppressing silica dust at the point of origin, protecting workers from silicosis and conforming to local occupational safety rules.
With underground mining and tunneling taking place in sensitive environmental ecosystems near Lake Kivu and Nyungwe, our drills feature integrated polyurethane mufflers that reduce operating decibels without creating significant exhaust backpressure.
We provide full technical documentation, certifications, and compliance support required by the Rwanda Mines, Petroleum and Gas Board, ensuring smooth custom clearances and rapid deployment approvals across local mining concessions.
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 in the industry. The company mainly produces over 500 kinds of products, such as pneumatic rock drilling tools, mining tools, DTH bits, coupling systems, and hollow self-drilling anchors.
By operating our own advanced metallurgical labs, steel forging plants, and precision computerized machining facilities, we ensure that every drilling rod, bit, and air-leg hammer is optimized for performance. We support mining projects across Africa, providing fast shipping, direct technical assistance, and customized tooling solutions for hard-rock drilling challenges.

Achieving high productivity and keeping operating costs low in Rwandan gold and coltan mines requires careful attention to the setup, air supply, and lubrication of pneumatic drilling equipment. Below is a professional operational guide for mine managers and drill technicians.
Pneumatic air-leg rock drills are engineered to operate at an optimal working pressure of 0.5 to 0.63 MPa (5 to 6.3 Bar). If pressure drops below 5 Bar, drilling speed decreases significantly, leading to higher friction and premature bit wear. If pressure exceeds 6.5 Bar, it accelerates the wear of internal components (such as the rifle nut and piston face) and increases risk of drill rod fractures. Ensure your mobile screw compressors are calibrated correctly and that line pressure drops are minimized by using heavy-duty hoses with internal diameters of at least 25mm.
Operating a pneumatic drill without lubrication will ruin the piston and cylinder within hours. An inline lubricator (such as the FY200B oiler) must be connected within 3 to 4 meters of the drill. The oiler should be filled with high-grade, adhesive pneumatic rock drill oil with the correct viscosity based on operating temperatures:
The operator must maintain constant, firm thrust using the telescopic air-leg. Under-thrusting causes the drill to bounce, damaging the chuck and shank end, and transferring high vibration to the operator. Over-thrusting slows rotation speed, overloads the pneumatic motor, and increases drill steel bending stresses, which can cause premature failure of the R32/T38 threads.
