The 4" FUJI Super Flex Grinding Wheel is a budget-friendly, flexible abrasive solution designed for precision grinding and finishing. Engineered with high-grade aluminum oxide abrasives, this wheel balances cost-efficiency with exceptional performance.
Unlike rigid wheels, the Super Flex series offers a "softer touch," reducing vibration and noise while maintaining aggressive cutting power. It is ideal for metalworking, automotive bodywork, and industrial maintenance where finish quality and operator comfort are paramount.
Understanding the difference between Flexible Grinding Wheels (2-3mm) and Standard Wheels (6-7mm) is crucial for choosing the right tool for the job. Here is the breakdown:
Properties: Rigid, hard as stone, does not deform under pressure.
Pros: High material removal rate. Like a "bulldozer," it removes thick welds fast.
Cons: High vibration, high heat (risk of burning workpiece), rough finish.
Best Use: Heavy grinding, chamfering, rough casting cleanup.
Properties: Semi-flexible, bends slightly under pressure to absorb vibration.
Pros: Cool cutting (dissipates heat), smooth finish, low vibration (less fatigue).
Cons: Not for extremely aggressive heavy stock removal.
Best Use: Curved surfaces, Stainless Steel (prevents discoloration), weld blending, and surface prep.
The Super Flex series is designed for 100mm (4-inch) angle grinders.
| Item | Dimensions (mm) | Abrasive | Grit Size | Max Speed |
|---|---|---|---|---|
| Super Flex 3mm | 100 x 3 x 15 | AWA (White Alumina) | 36, 46 | 72 m/s |
| Super Flex 2mm | 100 x 2 x 15 | AWA (White Alumina) | 60, 80, 100, 120 | 72 m/s |
*Note: The 15mm bore diameter can be modified to 16mm for export markets upon request.
Fuji Grinding Wheel is a leading manufacturer with over 70 years of history in Japanese abrasive engineering. We specialize in high-performance solutions for shipbuilding, automotive, and heavy industries. Our mission is to enhance productivity while ensuring user safety.
While it is reinforced with mesh fabric, it is designed for medium-duty tasks and finishing. For extremely fast heavy stock removal, we recommend our 6mm rigid wheels, but for precision finishing, the Super Flex is superior.
Yes! While optimized for steel and iron, the unique grain structure of the Super Flex helps prevent clogging when working on aluminum.
Tests show it operates at around 85dB, which is about 30% quieter than standard grinding wheels, reducing ear fatigue.

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.
