Grinding only; never use for cutting.
100mm × 2 or 3mm | T27 | 15mm Japan / 16mm overseas bore
Grits: 36, 46, 60, 80, 100, 120 | RPM: 72m/s
10 wheels/box; 20 boxes / 200 wheels/carton.
FUJI Super Flex is an economical 100mm (4-inch) T27 depressed-centre flexible grinding wheel for ordinary steel and castings. A selected blend of brown and white fused alumina provides practical grinding performance while keeping everyday abrasive costs under control. Both abrasive components are aluminum oxide.
Available in 2mm and 3mm thicknesses, its thin, patterned structure supports heat dissipation and a comfortable grinding action. It is designed to balance material removal, surface finish and operating cost. For grinding only; never use it to cut metal.
A single 100mm diameter with two thickness options. Choose it for everyday steel and casting grinding, weld blending and surface preparation where handling, heat control and finish matter.
For substantial stock removal or demanding rough grinding, compare a suitable thicker grinding wheel such as a matching Super F2 specification. Select by the workpiece and removal task rather than assuming one wheel is best for every operation.
Super Flex is not a dedicated stainless-steel wheel and is not suitable for aluminum. Choose a product specifically matched to those materials instead.
| Series / form | FUJI Super Flex / T27 depressed-centre flexible grinding wheel |
|---|---|
| Diameter / thickness | 100mm (4-inch) only / 2mm or 3mm |
| Factory-supplied bore | 15mm for Japan; 16mm for overseas markets |
| Abrasive | Selected blend of brown and white fused alumina (aluminum oxide) |
| Available grits | 36, 46, 60, 80, 100, 120; confirm the required thickness and grit combination when ordering |
| Maximum peripheral speed | 72m/s (approximately 4,300m/min); follow the wheel's marked maximum RPM |
| Materials / operation | Ordinary steel and castings / grinding only, not cutting |
| Packaging / availability | 10 wheels per box; 20 boxes / 200 wheels per carton. In stock; confirm the required specification and quantity. |
The 15mm and 16mm bores are factory-supplied options. Never enlarge or modify the bore yourself. The figures in m/min and m/s describe peripheral speed, not revolutions per minute. Match the grinder speed to the maximum RPM marked on the actual wheel.
Choose the grit according to the amount of material to remove and the required finish. Confirm thickness, bore, mounting accessories and grinder compatibility for the ordered wheel. Do not infer cutting suitability from the thin 2mm or 3mm profile.
Ordinary steel and castings. It is an economical steel-and-iron grinding wheel, not a dedicated stainless-steel product, and it is not suitable for aluminum.
No. Both 2mm and 3mm Super Flex wheels are for grinding only. Use a purpose-designed cutting disc for cutting metal.
Start with 36 or 46 for coarser grinding. Consider 60, 80, 100 or 120 when the task calls for a finer finish. Confirm the available grit and thickness combination with FUJI.
No. Order the factory-supplied 16mm version for compatible overseas equipment. Do not drill, enlarge or otherwise modify the bore.
No. Super Flex is designed for comfortable, low-noise grinding, but noise depends on the whole operation. Apply the required hearing protection and workplace exposure controls; no fixed decibel reduction is claimed.
With more than 70 years of abrasive-manufacturing experience, FUJI develops grinding solutions around material, application and operating requirements. Super Flex provides a practical, economical option for everyday steel and casting grinding.
Tell us your workpiece material, grinding task, preferred thickness, grit, bore and quantity. Include your current wheel and any problems with finish, heat or wear so FUJI can help select a suitable specification.
Contact FUJIChoosing 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.
