The FUJI Neo Flex Grinding Wheel (Super Flex Series) represents a significant evolution in abrasive technology for metal fabrication. Engineered for professionals who demand high-quality surface finishes, these 4-inch (100mm) wheels feature a unique 2mm to 3mm flexible resinoid bond.
Unlike traditional rigid grinding wheels that can gouge materials or cause "blue burn" marks, the Neo Flex conforms gently to the surface contours. This elasticity makes it the ultimate choice for curved surfaces, fine finishing, and pattern blending on stainless steel, carbon steel, and aluminum.
Why switch from standard rigid wheels? See the difference in industrial performance:
| Feature | Rigid Grinding Wheel | FUJI Neo Flex |
|---|---|---|
| Flexibility | None (Rigid) | High (Elastic) |
| Finish Quality | Rough, deep scratches | Smooth, paint-ready finish |
| Vibration | High | Low (-30%) |
| Risk of Gouging | High | Minimal |
Unlike conventional cold-pressed grinding discs that degrade quickly, the FUJI Neo Flex and Super Flex series are manufactured using our proprietary Japanese hot-pressing technology.
This advanced thermal curing process creates a denser, far more durable resin bond. The result? A grinding wheel that can operate safely at extreme industrial speeds (up to 72 m/s or 4,300 m/min) while lasting significantly longer. By requiring fewer wheel changeovers, the Neo Flex reduces industrial waste, making it a highly eco-friendly and cost-effective choice for high-volume foundries and shipyards.
The Neo Flex series is meticulously tailored for use on Stainless Steel, Carbon Steel, Cast Iron, and Non-Ferrous Metals.
| Dimensions (mm) | Series Type | Available Grit | Hardness/Bond | Max Speed | Pack Qty |
|---|---|---|---|---|---|
| 100 x 2 x 15 | Super Flex | AC 46, 60, 80, 120 | BF (Resinoid) | 72 m/s (4,300 m/min) | 200 pcs |
| 100 x 3 x 15 | Neo Flex | AC 36, 46, 60, 80 | BF (Resinoid) | 72 m/s (4,300 m/min) | 200 pcs |
*Custom Bore Sizes: The standard 15mm bore fits most Asian grinders. 16mm bore options are available for export markets upon request.
To unlock the ultimate finishing results and maximize operational efficiency, we highly recommend pairing these flexible wheels with our original FUJI Kosoku Angle Grinders.
Because we manufacture both the power tool and the abrasive consumable, the torque output and RPM of our Kosoku grinders are perfectly calibrated to complement the elastic bond of the Neo Flex. This precise synergy prevents the motor from stalling under heavy loads and extends the lifespan of the grinding disc far beyond competitor combinations.
While Neo Flex wheels offer superior safety compared to rigid wheels, always adhere to strict industrial protocols:
Both are flexible, but the Neo Flex (3mm) provides a slightly thicker cushion for finer finishing on specialized materials, while the Super Flex (2mm) offers an economical, aggressive cut for general steel and cast iron.
Yes, the AC grain structure works well on aluminum. However, for continuous, heavy aluminum fabrication, we recommend our specialized Non-Clogging Aluminum Wheels to completely prevent wheel loading.
Absolutely. Thanks to our hot-press manufacturing, they are rated for extreme industrial speeds up to 72m/s, making them fully compatible with standard electric, pneumatic, and high-frequency grinders.
Use Grit 36 or 46 for aggressive stock removal and grinding down heavy welds. Switch to Grit 80 or 120 for fine finishing, blending scratch marks, and surface preparation before final polishing or painting.

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.
