FUJI railway rail cut-off wheels for compatible rail saws and petrol-powered rail cutting machines.
Calculated RPM at 100 m/s: approximately 6,262 RPM (305 mm) or 5,380 RPM (355 mm). Always follow the maximum RPM marked on the wheel.
For rail replacement, track maintenance and installation. Match the wheel diameter, bore and speed to your machine.
The FUJI Type A railway rail cut-off wheel is designed for rail steel cutting during track maintenance, rail replacement and installation. Choose 305 mm (12 inch) or 355 mm (14 inch) to match your rail cutting machine. Both sizes feature three layers of fiberglass mesh reinforcement, a 4.5 mm thickness and a 100 m/s (6,000 m/min) maximum peripheral speed.
For railway contractors and maintenance teams, wheel selection should start with the rail material, machine model, diameter, bore and marked operating-speed limit. This is a dedicated rail cutting product; our GC masonry cut-off wheel for concrete, brick and stone is a separate solution.
Three layers of fiberglass mesh reinforce the resin-bonded abrasive structure for high-speed rail cutting. This reinforcement supports structural integrity and is a key safety feature of the wheel. It does not eliminate breakage risk or replace correct mounting, guarding and operation.
The high-speed rating supports efficient abrasive cutting on a compatible rail saw. Actual cutting time and wheel consumption depend on rail grade and section, machine power, feed and operating conditions. Compare time per completed cut and cuts per wheel in representative trials rather than assuming a fixed productivity gain.
100 m/s is the maximum peripheral-speed rating, not an instruction to run every saw at the same RPM. The required RPM depends on wheel diameter. The larger 355 mm wheel reaches the same peripheral speed at fewer revolutions than the 305 mm wheel.
| Dimensions (mm) | Thickness | Arbor (Hole) | Spec / Grade | Max Peripheral Speed | Calculated RPM at 100 m/s | Package Qty |
|---|---|---|---|---|---|---|
| 305 mm (12") | 4.5 mm | 25.4 mm | A24R BF | 100 m/s (6,000 m/min) |
Approx. 6,262 RPM | 25 pcs |
| 355 mm (14") | 4.5 mm | 25.4 / 22 mm | A24R BF | 100 m/s (6,000 m/min) |
Approx. 5,380 RPM | 25 pcs |
Conversion: 100 m/s = 6,000 m/min. RPM = 6,000 ÷ (π × diameter in metres). The RPM figures are mathematical conversions; follow the maximum RPM marked on the actual wheel. Confirm the bore size and packaging of the selected variant before ordering.
Use a compatible petrol cutting machine or stationary cut-off machine approved for this abrasive wheel and rail cutting application. Check its permitted wheel diameter, bore, flange arrangement, guard and maximum spindle speed. For a particular brand or model, request a compatibility check rather than assuming all petrol cutters accept the same wheel.
Secure the rail and use the machine’s specified rail clamp or guide. Where a stationary cutting setup is proposed, confirm approval for both the machine and the rail operation. Browse FUJI cutting machines for other cutting applications; the collection is not a blanket compatibility endorsement for this rail wheel.
Follow the project’s requirements for cut alignment, rail-end inspection and subsequent joining. Control cutting heat and inspect the rail end according to the project requirements.
Inspect the wheel before use and follow the wheel and machine instructions for mounting, guarding, workpiece support and protective equipment. Never exceed the marked wheel speed. Use the cut-off wheel for cutting only; avoid side grinding, twisting or forcing it in the kerf. Stop if abnormal vibration, binding or damage occurs.
305 mm (12 inch) and 355 mm (14 inch), both with a listed thickness of 4.5 mm. Choose the size approved for your rail cutting machine.
Three fiberglass mesh layers reinforce the wheel structure for high-speed cutting. Correct machine selection and operation remain essential for safe use.
Approximately 6,262 RPM for 305 mm and 5,380 RPM for 355 mm. These are conversion figures; the actual wheel marking determines the allowed RPM.
This product is for railway rail steel. For construction materials, see the FUJI GC masonry cutting wheel and check the relevant machine requirements.
No universal fit is implied. Confirm the machine model, permitted wheel size, bore, speed, flanges and rail attachment before purchase.

For professional export markets, always verify the Peripheral Speed (m/s) compatibility. Fuji wheels are designed to exceed JIS Burst Speed factors, but operating at the recommended R.P.M. ensures the longest tool life and cleanest cut.
Note: Mismatched grit or hardness can lead to excessive heat buildup, affecting the workpiece's structural integrity.
Global Maintenance Standard: To maintain the high safety factor of Fuji wheels, avoid exposure to excessive humidity and chemical solvents during storage. Proper care preserves the resinoid bond's strength, crucial for high-load industrial applications.
Fuji products are manufactured following strict Japanese standard process requirements. Every wheel is engineered to meet or exceed JIS (Japanese Industrial Standards), such as JIS R 6242 and B 4051. Our core engineering logic prioritizes maximum operator protection by maintaining safety factors and burst speed capabilities that often surpass the highest industry benchmarks.
| Standard Region | Safety Factor (Burst Multiplier) | Safety Logic & Benchmark |
|---|---|---|
| FUJI (High Precision) | > 2.0x | Engineered to exceed JIS requirements for maximum reliability. |
| Japan (JIS R 6242) | 2.0x | Extreme Safety: A wheel rated at 80m/s must withstand a 160m/s burst test. |
| Europe (EN 12413) | 1.73x | Risk Balanced: Provides high safety redundancy for most industrial apps. |
| USA (ANSI B7.1) | 1.5x | Efficiency Focused: Relies on machine guarding and operational procedures. |

When deploying Fuji high-performance tools in overseas markets, ensure that the regional power grid frequency and voltage match the tool specifications. To maintain the superior burst speed safety of Fuji wheels, store abrasives in a dry, temperate environment. Humidity can degrade the resin bond, potentially lowering the wheel’s resistance to centrifugal forces.
