The FUJI NATTOKU High-Performance Grinding Wheel delivers industrial-grade precision with unmatched safety and durability. Engineered for the most demanding applications, it features an 80m/s max peripheral speed rating to prevent edge chipping even under extreme grinding conditions.
Its advanced vibration-dampening design significantly reduces operator fatigue and lowers the risk of vibration-related injuries (HAVS). With minimized heat generation, NATTOKU ensures precision on thin steel plates without warpage. Furthermore, its ultra-low dust emission technology prioritizes worker health by reducing pneumoconiosis risks.
Choose the right specification for your grinding needs. The NATTOKU series is optimized for depressed center grinding applications.
| Dimensions (mm) | Dimensions (inch) | Grit / Spec | Max Speed | Packaging |
|---|---|---|---|---|
| 100 x 6 x 15 | 4" x 1/4" x 5/8" | WA 36P | 4,300 m/min (72m/s) | 25/200 pcs |
| 125 x 6 x 22 | 5" x 1/4" x 7/8" | WA 36P | 4,300 m/min (72m/s) | 25/100 pcs |
| 150 x 6 x 22 | 6" x 1/4" x 7/8" | WA 36P | 4,300 m/min (72m/s) | 25/50 pcs |
| 180 x 6 x 22 | 7" x 1/4" x 7/8" | WA 36P | 4,300 m/min (72m/s) | 25/50 pcs |
* Note: The 15mm bore diameter can be modified to 16mm for export markets upon request.
The NATTOKU series is versatile, suitable for a wide range of materials and industries:
The unique bonding agent and grain structure minimizes particle separation, resulting in 70% less airborne dust.
Yes. The heat-reducing technology prevents the "blue burn" often seen on thin stainless steel plates.
All FUJI wheels are ISO 9001 certified and meet JIS (Japanese Industrial Standards) for safety.
FUJI GRINDING WHEEL is a leading manufacturer with 70 years of expertise. We provide professional abrasive solutions for industries worldwide.
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.
