Portable Rail Drilling Machine (Petrol‑Driven Field Rail Drill)
This portable rail drilling machine is lightweight field‑use drilling equipment for making steel rail bolt holes. Powered by a reliable Honda gasoline engine, it works completely off‑grid with no external power source required. Equipped with an independent manual cooling water tank, it greatly extends carbide drill‑bit service life. Widely applied for rail joint fish‑plate holes and signal bonding holes during new track construction, routine maintenance and emergency repair. Quick‑lock clamping fixture supports single‑person stable operation for multiple standard rail types.

Product Description
Product Advantages
●Portable Off‑grid Performance
Compact lightweight gasoline‑driven structure, no generator or power cable needed. Easy to carry and transfer, perfectly fit remote track sections without power supply.
●Independent Water‑cooling Configuration
Matched manual pressure cooling water tank continuously cools drill bits during operation, effectively reducing high‑temperature abrasion and prolonging carbide drill‑bit service life.
●Quick‑Lock Rail Clamping Fixture
Fast‑adjust clamping mechanism firmly locks on rail web, prevents position offset while drilling, guarantees vertical and precise hole location.
●Wide Application Compatibility
Supports hollow bits and twist bits. Suitable for fish‑plate connection holes, signal bonding holes on main‑line rails, turnouts and metro tracks.
●Convenient On‑site Maintenance
Modular structural design. Wearing parts such as drill bits and sealing assemblies can be replaced directly on the track without complex disassembly.
FAQ
Frequently Asked Questions
Q1: Does this portable rail drill require an external power supply?
A1: No. It adopts a Honda gasoline engine for fully off‑grid operation, which is ideal for remote field track sections with no power infrastructure.
Q2: What kinds of rails can this portable drilling machine adapt to?
A2: It works for standard 43 kg/m, 50 kg/m, 60 kg/m and 75 kg/m steel rails of railway and metro lines.
Q3: What is the function of the supporting water tank?
A3: The manual‑pressure water tank provides cooling liquid for drill bits. It lowers high‑temperature wear and extends carbide drill‑bit service life.
Q4: What drill‑bit sizes does this machine support?
A4: It is compatible with Φ12 mm‑Φ32 mm hollow drill bits and twist drill bits for rail bolt holes and signal holes.
Q5: Can you provide supporting spare parts?
A5: Yes. We supply carbide drill bits, water‑tank accessories, engine spare parts together with the complete operation manual. OEM service is available.
