Equipped with a large-capacity lithium battery pack (8.0Ah-12.0Ah per unit, supporting dual-battery alternation), completely eliminating the cable drag of traditional wired drilling machines, making it suitable for power-free scenarios such as railway main lines, tunnels, and bridges; the body is made of high-strength lightweight alloy material, with a total weight controlled at 8-12kg, allowing for single-person transport and operation. Compared to pneumatic drilling machines, it is 40% lighter, significantly reducing the labor intensity of outdoor operations. 2. High-efficiency drilling capability, adaptable to multiple rail specifications. Built-in high-power brushless motor (800W-1500W), combined with carbide/diamond coated drill bits, it can drill holes from 12mm to 32mm (compatible with mainstream railway rail specifications), handling different rail types such as 43kg/m, 50kg/m, 60kg/m, and 75kg/m. A single drilling operation takes only 15-45 seconds (adjusted according to hole diameter and rail material), increasing efficiency by more than 20 times compared to manual drilling, meeting the core requirements of railway maintenance for "rapid repair and efficient construction." 3. Precise Positioning + Stable Output, Reducing Rework Rate Equipped with a laser positioning device and graduated scale, the drilling positioning accuracy reaches ±0.1mm, avoiding rail scrapping caused by hole position deviation; the machine body integrates a shock absorption and buffer mechanism, controlling the amplitude within 0.5mm during drilling to prevent rail cracks caused by vibration; the built-in torque feedback system automatically adjusts the speed when the drill bit encounters hard points or jams, avoiding motor overload damage, and achieving a drilling success rate of over 99.5%. II. Technical Highlights: Professional Configuration Solidifies Railway Operation Advantages

1. Drilling and Cooling System, Adapted to the High Hardness Characteristics of Rails
Drill Bit Technology: Uses cobalt-containing cemented carbide or PCD diamond-coated drill bits, with a hardness of HRC60 or higher, excellent wear resistance, and a single drill bit can continuously drill 50-100 holes (depending on the rail material); supports a quick drill change structure, allowing drill bit replacement in 30 seconds. Cooling Design: Features a built-in high-pressure air cooling + spray cooling dual system. The air cooling system rapidly dissipates heat to protect the motor, while the spray system sprays special cooling oil (or water-based coolant) to reduce drill bit temperature and wear, while preventing annealing and softening at the rail drilling site. 2. Lithium Battery and Safety Protection for Complex Railway Working Conditions Battery Performance: Utilizes lithium iron phosphate batteries with a cycle life exceeding 2000 cycles, supporting operation in extreme environments from -25℃ to 60℃, suitable for railway operations in cold and hot regions; dual-battery operation supports 80-120 drilling operations, and fast-charging technology (100% charge in 60 minutes) ensures continuous operation. Safety Protection: Equipped with four mechanisms: overload protection, over-temperature protection, anti-jamming protection, and leakage protection; IP55 protection rating, dustproof, waterproof, and splashproof, suitable for dusty and rainy working environments along railway lines; equipped with a safety lock trigger to prevent accidents caused by misoperation. 3. Humanized and Intelligent Design for Enhanced Operation Convenience
Operation Optimization: The two-way grip with anti-slip soft rubber design is ergonomic, reducing fatigue during prolonged use. Wireless remote control (on some high-end models) allows for remote control of drilling start and stop, avoiding close contact between operators and the drilling area.
Intelligent Monitoring: The LCD screen displays real-time parameters such as remaining battery power, drilling speed, coolant level, and work count. Some models support Bluetooth connectivity, allowing users to record drilling location, quantity, and time via a mobile app for easy maintenance and traceability.
III. Typical Application Scenarios: Focusing on Railway Full-Scenario Maintenance
Railway Mainline Maintenance and Emergency Repair: Applicable to rail drilling operations on conventional and high-speed railways (such as rail joint connections, turnout installation, and fastener fixing hole drilling). The cordless design enables rapid response to sudden faults and repairs, avoiding construction delays caused by cable deployment. 2. Urban Rail Transit Construction: Used for rail laying and maintenance in subways, light rail, and suburban railways. Its compact body is suitable for operation in confined spaces such as tunnels and elevated sections. Its low-noise design (≤85dB) meets urban construction environmental protection requirements.
3. Turnout Installation and Modification: Turnout areas require dense drilling of bolt holes and positioning holes. Precise positioning ensures perfect fit between holes and turnout components, while efficient drilling shortens the turnout installation period.
4. Railway Bridge and Tunnel Operations: Power access is difficult in bridges and tunnels. Lithium-ion battery drive eliminates the need for external power. Vibration-resistant design prevents drilling vibrations from affecting the stability of the bridge structure. Dustproof and waterproof performance is suitable for the humid and dusty environment inside tunnels.
5. Railway Emergency Rescue: Responding to sudden failures such as rail breakage and fastener damage, rapid drilling allows for rail splicing or temporary reinforcement, buying time for rescue and reducing railway downtime losses. IV. Purchasing Guide: Select Railway-Specific Drilling Equipment According to Your Needs

1. Priority of Core Parameters

Drilling Specifications: Select according to the type of rail being drilled (standard selection: 12mm-32mm hole diameter; larger hole diameters can be customized for special scenarios);

Motor Power: 1200W-1500W for heavy-load scenarios (75kg/m rails, large-diameter drilling); 800W-1200W for standard scenarios;

Battery Configuration: Prioritize dual batteries with a capacity of 8.0Ah or higher, supporting fast charging and low-temperature adaptability (operable at -25℃);

Accuracy and Durability: Select models with positioning accuracy within ±0.1mm, drill bit wear resistance rating of HRC60 or higher, and machine body protection of IP55 or higher. 2. Brand and Scenarios Compatibility Professional Recommendations: CRCC Heavy Industry (leading manufacturer of railway-specific equipment), Bosch (industrial-grade heavy-duty series), Makita (professional rail transit tools), CRRC Times Electric (compatible with high-speed rail standards). These brands' products comply with railway industry standards, and after-sales support includes on-site calibration and repair. Niche Brand Selection: Focus on battery warranty (preferably 2 years or more), drill bit compatibility, and whether they provide railway industry certifications (such as CRCC certification). V. Usage and Maintenance Techniques: Extending Equipment Lifespan and Ensuring Operational Safety

1. Correct Usage Guidelines

Before Operation: Check the rail surface for oil stains and rust (clean if necessary), calibrate the concentricity of the laser positioning device and drill bit; select the appropriate drill bit according to the rail material (carbide drill bits for ordinary rails, diamond-coated drill bits for high-manganese steel rails);

During Operation: Keep the machine body perpendicular to the rail, turn on the cooling system before starting drilling; avoid prolonged continuous operation (it is recommended to stop and allow the machine to cool down for 5 minutes after drilling 10 holes); if the drill gets stuck, immediately release the trigger, turn off the power, and clean the drill bit and hole; do not force restart.

Safety Precautions: Wear safety goggles, cut-resistant gloves, and hearing protection equipment while operating; drilling at rail joints or cracked areas is strictly prohibited. 2. Daily Maintenance Points
Drill Bit Maintenance: Clean residual iron filings from the drill bit promptly after drilling and apply anti-rust oil; replace the drill bit promptly when it is severely worn (drilling speed significantly reduced, hole wall rough) to avoid motor overload due to drill bit dulling;
Battery Maintenance: Store in a dry, ventilated environment, avoiding contact with metal objects; if not used for an extended period (more than 1 month), fully charge before storage, and recharge every 3 months;
Machine Body and Cooling System: Clean the machine body's heat dissipation vents and cooling system nozzles weekly, and check the coolant level (replenish with dedicated coolant if insufficient); check the motor carbon brush wear monthly (replace when wear exceeds 1/2);
Regular Calibration: Calibrate the positioning accuracy and torque sensor every 3 months, and conduct a comprehensive inspection annually (motor power, battery capacity, drilling accuracy) to ensure the equipment meets operating standards.
