|---|---|---|---|---|
| Star Flex | 100 x 3 x 15 | #36, #46, #60, #80, #120 | 72 m/s (4,300 m/min) | Steel, Cast Iron, Stainless |
| Star Flex | 125 x 3 x 22 | #36, #46, #60, #80, #120 | 72 m/s (4,300 m/min) | Steel, Cast Iron, Stainless |
*Note: The 15mm bore diameter can be customized to 16mm for export markets upon request.
Why switch to Star Flex? Compared to standard depressed center wheels, Star Flex offers:
Fuji Grinding Wheel is a leading manufacturer and supplier of industrial grinding solutions. With over 70 years of expertise, advanced manufacturing technology, and a commitment to excellence, we provide precision-engineered abrasive solutions for metalworking, construction, and automotive industries globally.
The patterned slits allow air to flow between the wheel and the workpiece, which cools the grinding zone. They also provide a channel for debris to escape, preventing the wheel from clogging.
Yes, it is excellent for stainless steel. The cool cutting action prevents "blue burn" (heat discoloration) often caused by rigid wheels.
Use #36 or #46 for initial stock removal and weld grinding. Use #80 or #120 for blending, finishing, and preparing surfaces for painting.

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.
