FUJI 305-455mm Chop Saw Cutting Discs are engineered in Japan for professionals who demand precision and durability on stationary cutting machines. Designed for heavy-duty applications, these discs feature a robust 2.8mm - 3.5mm thickness and are capable of withstanding bending up to 60 degrees without cracking, ensuring superior safety and stability.
Available in two specialized formulations—Hakusan (White) for precision/stainless work and Rafuton (Black) for heavy-duty carbon steel—FUJI discs are the trusted choice for shipyards, construction sites, and fabrication plants worldwide.
The Specialist for Stainless Steel & Alloys
Leverages self-sharpening White Aluminum Oxide (WA) abrasive. This formulation cuts cooler and cleaner, making it ideal for hard-to-cut materials.
The Workhorse for Carbon Steel
Employs an advanced Mixed Aluminum Oxide (A/WA) abrasive with a proprietary tough bond. Built for high-volume, aggressive cutting tasks.
Choose the right specification for your machine. Note that larger diameters (405-455mm) require compatible industrial machines.
| Series | Diameter | Thickness | Arbor | Grit Type | Max Speed | Pack Qty |
|---|---|---|---|---|---|---|
| Hakusan (Stainless) |
305 mm (12") | 2.8 mm | 25.4 mm | WA36N | 72 m/s | 25 |
| 355 mm (14") | 3.0 mm | 25.4 mm | WA36N | 72 m/s | 25 | |
| 405 mm (16") | 3.0 mm | 25.4 mm | WA36N | 63 m/s | 25 | |
| 455 mm (18") | 3.5 mm | 25.4 mm | WA30N | 63 m/s | 20 | |
| Rafuton (Carbon Steel) |
305 mm (12") | 2.8 mm | 25.4 mm | AWA36P | 72 m/s | 25 |
| 355 mm (14") | 3.0 mm | 25.4 mm | AWA36P | 72 m/s | 25 | |
| 405 mm (16") | 3.0 mm | 25.4 mm | AWA30P | 63 m/s | 25 | |
| 455 mm (18") | 3.5 mm | 25.4 mm | AWA30P | 63 m/s | 20 |
For optimal performance, especially with larger 405mm and 455mm discs, we recommend pairing them with high-rigidity Stationary Cutting Machines.
A: Choose the Hakusan Series. Its White Aluminum Oxide (WA) abrasive is specifically designed to cut stainless steel without causing overheating or rust-inducing contamination.
A: No. Never exceed the maximum diameter or RPM rating of your machine. 405mm discs require larger, industrial-grade machines like the FUJI FS-Series for safe operation.
A: Thicker discs offer greater lateral stability, ensuring the cut remains straight (doesn't wander) when cutting through thick solid bars or heavy beams.
Since 1953, FUJI Grinding Wheel has been a leader in Japanese abrasive technology. We supply the global market with premium cutting and grinding solutions for the shipbuilding, automotive, and heavy industries.

Choosing the correct abrasive wheel is critical for both operational efficiency and JIS-compliant safety. Fuji Grinding Wheels are engineered with precise technical markings to ensure the perfect match for your specific material and machine requirements.
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.
