The FUJI 115mm (4.5") Grinding Wheel defines efficiency in professional metalworking. Engineered to tackle the strict demands of industrial applications, these premium Fuji grinding discs integrate carefully selected 24S/36S abrasive grains.
What sets this wheel apart is our proprietary Japanese Thermal Pressure Technology. Unlike conventional cold-pressed alternatives, this manufacturing breakthrough forges a wheel structure with superior density, providing exceptional self-sharpening traits and consistent material removal rates from the first spark to the last.
Measuring 115mm (4.5 inches)—the most popular size in European and American markets—it balances high power with portability, fully compatible with all standard angle grinders.

Shipbuilding involves working with thick steel plates and harsh marine environments. Fuji’s 115mm grinding wheels tackle these challenges with ease:
In fabrication shops where accuracy and speed are paramount, Fuji’s wheels streamline critical processes:
From bridges to high-rise buildings, our wheels prove invaluable for on-site structural steel work. The 115mm diameter offers optimal maneuverability for contour work on I-beams and rebar smoothing.
Resinoid-bonded wheels (like the Super F2) are organic and age over time. Note on Standards: While the Japanese Industrial Standard (JIS) does not mandate a strict expiration date, FUJI prioritizes maximum safety.
FUJI Official Recommendation:
Always check the metal ring (blotter) for the Manufacturing Date.
Other Safety Protocols:
See what professional users on the Japanese Rakuten Platform are saying about the Super F2 series durability and balance.
A: Thermal pressure applies heat during the molding process, creating a much denser bond. Cold-pressed discs often wear irregularly, while our thermal wheels provide consistent grain retention and 30% longer life.
A: Yes. The abrasive formulation is free from iron, sulfur, and chlorine, making them safe for Stainless Steel without causing rust or corrosion.
A: Always wear PPE (goggles, gloves, dust mask), never exceed the recommended RPM (72m/s), and ensure the angle grinder guard is properly installed.
A: This size balances maneuverability and material removal capacity. It matches the most common industrial angle grinders, making it suitable for both detailed contour work and heavy surface grinding.
A: Thanks to the high-density structure, Fuji wheels typically outlast standard generic wheels by 20-30%, reducing the frequency of wheel changes and lowering total project costs.

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.
