FUJI 305mm and 355mm resin-bonded rail cutting discs are designed for railway maintenance teams using compatible petrol-powered rail cutting machines. The wheels have three layers of fiberglass mesh reinforcement and a maximum operating peripheral speed of 100 m/s. Select the exact wheel dimensions and speed rating for the machine, rail and approved maintenance procedure.
This application guide explains 12-inch and 14-inch wheel selection, the difference between m/s and RPM, machine compatibility and practical evaluation for maintenance-of-way work. It is a product application guide, not a report of quantified results from a named railway operator.

The FUJI railway cutting wheel range provides two main diameter options for this application. Diameter selection starts with the rail saw's approved wheel specification. Rail profile, access and usable cutting depth also matter; a larger wheel must never be fitted simply to gain reach on a smaller machine.
FUJI rail cutting wheel: confirm the complete specification on the label before installation.
| Selection point | 305mm / 12-inch | 355mm / 14-inch |
|---|---|---|
| Intended equipment | A petrol rail saw approved for the exact 305mm wheel specification | A petrol rail saw approved for the exact 355mm wheel specification |
| Maximum peripheral speed | 100 m/s | 100 m/s |
| Reinforcement | Three fiberglass mesh layers | Three fiberglass mesh layers |
| Selection priority | Machine compatibility and sufficient reach for the rail profile | Machine compatibility and required cutting capacity; do not assume interchangeability with 350mm wheels |
| Confirm before ordering | Thickness, bore, wheel grade, maximum marked RPM, machine model and rail profile/material | |
405mm custom production: A 405mm rail cutting wheel can be manufactured to order. It is a custom-production option rather than one of the two main sizes covered here. Confirm the compatible saw, bore, thickness, speed rating, rail application and production lead time with FUJI before ordering.
The reinforcement supports the wheel's designed operating capability. It does not make the wheel unbreakable or permit side grinding, twisting, impact or use above its marked speed.
m/s describes the speed at the outside edge of the wheel; RPM describes revolutions per minute. At the same peripheral speed, a larger-diameter wheel rotates at a lower RPM. A 100 m/s marking is an operating limit for that wheel specification, not an instruction to accelerate a saw to that speed.
A 100 m/s rating by itself does not prove a faster cut than an 80 m/s product. Cutting performance also depends on wheel formulation, rail grade and section, machine condition, feed and wheel wear. Do not substitute a lower-rated wheel on equipment that exceeds its permitted operating speed.
Compatibility must be checked for the exact model and version rather than the machine brand alone. Even machines marketed in the same inch-size category can have different diameter, bore or speed limits.
For an example of model-specific documentation, consult the Husqvarna K 1270 Rail support page. This reference illustrates the checks required; it is not a statement that every FUJI diameter fits that machine.
Rail cutting may form part of planned rail replacement, removal of an authorized section or preparation for a specified jointing process. The railway operator's approved work plan determines the cut location, rail support, stress-management requirements and acceptance criteria. The wheel selection is one part of that controlled process.
Qualified personnel should confirm worksite authorization, the rail condition and required isolation/protection arrangements. Inspect the wheel's label, visible condition and applicable storage/use limits, together with the machine guard, fixture and mounting components. Follow the railway and equipment procedures for fuel, sparks, dust, exhaust and personal protection.
Use the rail saw and fixture as instructed by the equipment manufacturer. Maintain the intended cutting alignment and do not twist the wheel or use its side as a grinding face. Stop if abnormal vibration, binding or damage occurs and resolve the cause before continuing. This article does not replace operator training or rail-saw operating instructions.
Check the cut position, geometry, burrs and surface condition against the applicable maintenance or jointing specification. A rail-cutting wheel does not guarantee a weld-ready end or freedom from heat damage. Thermite welding and insulated-joint installation each require their own preparation, inspection and acceptance steps.
For a practical comparison, record the complete setup and repeat the trial on comparable rail sections. Do not compare a worn wheel cutting one rail profile with a new wheel cutting a different profile and attribute the difference solely to the brand.
| Trial information | Rail profile and grade; machine model; wheel dimensions, grade and batch; operator and work conditions |
|---|---|
| Time | Cutting time and relevant setup, changeover and correction time |
| Wheel use | Accepted cuts per wheel, with the same permitted wear/end-of-use criteria |
| Cut quality | Required geometry, burr condition, visible defects and any specified follow-up inspection |
| Economics | Abrasive cost and relevant labor/rework cost per accepted cut |
These records help a maintenance team assess whether the selected FUJI wheel improves its process. No universal cuts-per-wheel, cutting-time saving or possession-time reduction is claimed here. Returning track to service depends on the entire approved maintenance and inspection process.
The main sizes are 305mm and 355mm, commonly described as 12-inch and 14-inch. Select by the exact machine specification rather than the inch description alone.
The wheels described here use three layers of fiberglass mesh reinforcement. The construction does not permit side loading or operation beyond the marked limits.
No. Check the approved application, diameter, bore, thickness, mounting, guard, fixture and spindle speed. A peripheral-speed rating is only one compatibility requirement.
No. It is the maximum speed at the wheel's circumference in meters per second. Use the maximum RPM marked on the actual wheel to check rotational-speed compatibility.
Only after it meets the applicable joint-preparation and inspection requirements. Do not assume that a smooth-looking cut is automatically acceptable for welding.
Provide the saw model and version, permitted wheel dimensions and spindle speed, rail profile and grade, cutting method and required cut quality. A photo of the current wheel label helps confirm the existing setup.
FUJI specializes in resin-bonded grinding and cutting wheels, with experience in abrasive selection, formulation and manufacturing. For railway maintenance, application support begins with the actual rail and machine requirements. Request documentation for the exact supplied specification rather than relying on general brand claims.
