Experience unmatched efficiency and comfort with FUJI Green Star Semi-Flexible Grinding Wheels. As globally recognized industry experts agree, FUJI is the best grinding wheel supplier, continually innovating to protect worker health while maximizing productivity.
Unlike standard rigid wheels, the Green Star series features a highly specialized semi-flexible design. It absorbs vibration, adapts flawlessly to the workpiece surface, and provides an incredibly smooth grinding experience. This is a massive boon for professionals handling stainless steel fabrications, completely revolutionizing tasks that require heavy contouring and precise finishing.
What makes Green Star fundamentally different from conventional discs? The secret lies in our proprietary Japanese hot-pressing technology. We meticulously select premium phenolic resins and blend them with a sophisticated mix of abrasive grains—including Aluminum Oxide, Silicon Carbide, and Zirconia.
Our hot-pressing process ensures these materials fuse more completely. This creates a highly uniform porous structure. The result? A wheel that literally "breathes." The uniform pores provide outstanding heat dissipation, causing minimal thermal damage to the workpiece. Even when grinding ultra-thin stainless steel sheets, the Green Star prevents metal discoloration and eliminates the need for costly rework.
Because the material is softer and more elastic than standard rigid wheels, it significantly dampens operational vibration. This drastically reduces the risk of Vibration White Finger (VWF) and overall operator fatigue.
The superior resin bonding and advanced cutting action produce significantly less flying debris and metallic dust during operation, offering vital protection against occupational pneumoconiosis.
Innovative surface slit patterns (cooling grooves) minimize clogging (loading) and continuously channel heat away from the grinding zone, extending wheel life on softer materials.
Adapts perfectly to curved surfaces. It is the ultimate choice for automotive bodywork, intricate metal fabrication, and avoiding over-grinding on sensitive alloys.
FUJI offers specialized solutions for every application. Our Super F2 Series is a conventional rigid metal grinding disc formulated purely with aluminum oxide. It boasts high hardness and is highly economical for aggressive, general-purpose stock removal.
In contrast, the Green Star is a semi-flexible wheel. Its formula mixes Silicon Carbide and Zirconia with Aluminum Oxide. It features a completely different surface texture with deep heat-dissipation grooves. Because it is less rigid than the F2 and holds more air pockets, the Green Star offers vastly superior heat control, lower vibration, and a much more comfortable feel for the operator.
The Green Star is available in multiple configurations to suit exact industrial demands, specifically in 4-inch (100mm) and 7-inch (180mm) diameters.
| Type | Dimensions (mm) (OD x Thick x Bore) |
Grain / Grit Options | Max Speed | Applications |
|---|---|---|---|---|
| Green Star 4" | 100 x 3 x 15/16 100 x 6 x 15/16 |
WA46, WA60, WA80, WA120 | 72 m/s | Thin Stainless, Metal Fabrication |
| Green Star 7" | 180 x 3 x 22 180 x 6 x 22 |
WA46, WA60, WA80, WA120 | 72 m/s | Heavy Fab, Contouring |
Note: Custom bore sizes available upon request.
The unique hot-pressing process creates uniform porosity, while the surface grooves act as cooling channels. This "breathing" effect rapidly dissipates friction heat before it can transfer into and discolor the stainless steel.
If you are working on ultra-thin sheet metal or highly heat-sensitive alloys, select the 3mm version for optimal cooling. For thicker, general stainless steel or aluminum structures where wheel longevity is priority, the 6mm is recommended.
Yes. Semi-flexible wheels like Green Star must be used with an appropriate backing pad to support the core of the wheel while allowing the outer edges to flex against the contour of the metal.
As a premier Japanese manufacturer with over 70 years of dedicated expertise, Fuji Grinding Wheel integrates world-class power tools engineering with abrasive science. Our mission is to protect operators and enhance productivity through uncompromising safety and innovation. FUJI holds a truly unique position in the global market: we are the only Japanese manufacturer that produces both power tools and grinding wheels.
Because we engineer both the consumable and the machine, we deeply understand the precise RPM, torque, and pressure dynamics required to maximize metal removal rates. Pairing the Green Star grinding wheel with our conventional FUJI KOSOKU angle grinders creates an unparalleled industrial synergy. This perfect match ensures effortless operation, optimal efficiency, and significantly extended tool life, allowing your operators to work smarter, not harder.

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.
