Our most widely deployed heavy-duty jackhammers, optimized for the rigorous geological realities of Brazilian ore basins and infrastructure tunneling.
Brazil stands as a global powerhouse in mineral extraction. From the vast iron ore complexes of the Carajás Basin in Pará to the gold, bauxite, and copper veins of Minas Gerais and Bahia, the geological demands are intense. In these severe environments, rock drill tools are subjected to high abrasiveness, extreme compressive rock strengths, and remote operational configurations.
While massive rotary jumbo rigs dominate high-volume open-pit mining, air leg pneumatic rock drills remain the indispensable frontline equipment for underground development, narrow-vein mining operations, slope stabilization, and quartzite quarrying across Brazil. Their portability, mechanical simplicity, and massive power-to-weight ratio make them critical where heavy track-mounted machines cannot traverse.
Understanding the specific mechanical parameters needed to drill Brazil's unique geology.
Below is an engineering comparison matrix of standard air leg rock drills exported to Brazil, showcasing high-impact frequency and torque levels optimized for varying geological strata.

Request Custom Engineering SupportShandong E-Way Machine Co., Ltd. leverages a highly optimized smart-factory framework to secure a reliable global export pipeline. While regional distributors in Brazil sometimes suffer from spotty part availability and shipping bottlenecks, our comprehensive logistics control ensures steady delivery of tools and critical spares.
From metallurgical choice to automated testing benches, every air leg rock drill undergoes exhaustive calibration. Standardized replacement parts—pistons, rifle bars, rotating sleeves, water tubes, and air distribution valves—are manufactured in-house using premium alloys and high-grade heat treatments. This ensures maximum service life and minimizes downtime in underground drilling headings.
Shandong E-Way Machine Co., Ltd. is a modern industrial equipment manufacturer dedicated to the research, development, production, and service of high-quality machinery and engineering solutions. With a strong focus on technological innovation and manufacturing excellence, the company serves customers in mining, construction, and various heavy-duty industrial sectors worldwide.
Over the years, Shandong E-Way Machine has developed a diversified product portfolio covering mining and construction drilling equipment, pneumatic and hydraulic tools, anchoring and support systems, mechanical transmission components, and a wide range of spare parts and accessories. In addition, the company provides customized machining services, including precision components, structural parts, and wear-resistant engineering plastic products, meeting the specific needs of different working conditions and industries.
Navigating the Brazilian mining sector requires compliance with strict safety directives. The Ministry of Labour and Employment enforces NR-12 (Machinery and Work Equipment Safety) and NR-22 (Occupational Health and Safety in Mining). Uncertified machinery can result in site closures and major liabilities.
Our export-grade air leg rock drills are optimized to meet these standards. Features include vibration-isolating control handles to protect operators from long-term hand-arm vibration syndrome (HAVS), optimized exhaust muffling to keep noise emissions in check, and dual control valves that prevent accidental activation if pneumatic pressure drops suddenly.
Additionally, our wet-drilling components guarantee continuous water injection directly to the drilling face. This suppresses airborne crystalline silica dust, protecting operators and ensuring compliance with the stringent particulate limits required by Brazilian mine inspections.
Developing advanced mechanical dampening structures to reduce operator handle vibration below 5m/s², comfortably exceeding NR-12 compliance requirements.
Phasing in a new generation of micro-alloyed steel components to increase the life cycles of pistons and rifle nuts by up to 35% in high-abrasiveness iron formations.
Deploying micro-dosing inline lubricators to reduce oil mist exhaust emissions, improving underground air quality and operator safety.
Our complete line of high-performance pneumatic systems and crawler-mounted rigs configured for Brazilian excavation, tunneling, and civil engineering works.
Expert guidance on logistics, technical maintenance, compliance, and custom ordering for South American commercial distributors.
Standard sea freight shipments dispatch from Qingdao Port directly to major Brazilian maritime terminals, primarily the Port of Santos (São Paulo) and Port of Paranaguá (Paraná). Ocean transit times usually range between 35 to 45 days. We prepare detailed documentation including the Bill of Lading (B/L), Commercial Invoice, packing lists, and Certificate of Origin (CO) to streamline customs clearance through Receita Federal.
Our mining tools are manufactured to satisfy strict physical safety constraints. Vibration damping options are available for handles, keeping operator exposure below structural safety limit thresholds. We provide clean, physical-safety labeling, and can supply full operations manuals in Portuguese, helping you satisfy the local audit needs of regulatory bodies.
We use premium 20CrNiMo alloy steel for pistons and crucial internal rotation elements. This material undergoes a specialized gas carburizing process followed by precision hardening. The result is a rock-hard outer wear surface (HRC 58-62) with a resilient inner core, preventing early structural fatigue when drilling through dense ores.
The YT28 air leg rock drill strikes an optimal balance between weight (28kg) and impact energy (more than 70 Joules at 0.63 MPa). It handles high-torque rotation, resists dynamic clogging during water-flushing, and integrates seamlessly with telescoping air legs (FT160A or FT160B) to minimize operator fatigue in narrow-vein spaces.
Through our dedicated R&D division, we can adapt tools to suit localized operations. Whether you require specific air-leg connection dimensions, altered shank sizes (e.g., customized Hex 25mm to fit legacy tooling inventories), or enhanced water-injection rates for highly dust-prone formations, we can engineer custom batches. Contact our technical team to finalize specifications.
For high-intensity operations, we suggest a visual assessment every shift (lubricant levels, shank wear). Detailed inspections should occur every 100 operating hours, checking the rifle nut and piston face. A complete strip-down cleaning and seal replacement is recommended every 500 hours to maintain peak drilling velocity and air efficiency.
