The FUJI Gold Raicho Cutting Disc 125*2.5mm is a premium cutting solution engineered for professionals who demand exceptional performance and longevity. Designed specifically for 5-inch (125mm) handheld angle grinders, this disc combines advanced Japanese abrasive technology with rigorous manufacturing standards.
Crafted with a unique sharp abrasive formula, the disc achieves an optimal balance between speed and durability. Its 2.5mm thin design ensures low-resistance cutting, while the proprietary bond extends service life to 1.5–3 times longer than conventional discs. This translates to fewer changes, increased productivity, and lower long-term costs.
Meeting strict Japanese Industrial Standards (JIS), it is the reliable choice for metal fabrication, automotive repair, and construction.

Industrial Applications
The FUJI Gold Raicho excels in environments where precision and reliability are non-negotiable:
✔Metal Processing Plants: Continuous cutting of steel bars and sheets. Reduces production interruptions.
✔Automotive Repair: Ideal for exhaust pipes and chassis trimming in tight spaces.
✔Construction: Cutting rebar and structural steel on-site. Lightweight for high-altitude work.
✔Shipyards: Processing marine-grade steel plates and pipes with high wear resistance.
✔Fabrication: Delivers precision, burr-free cuts on stainless steel for accurate assembly.
⚠️ Safety & Storage Guidelines
Shelf Life: Recommend to use within 3 years of manufacture. Store in a dry environment (< 60% humidity) to prevent moisture damage.
Dry Cutting Only: Do not use with water or coolants, as this degrades the resin bond.
PPE Required: Always wear safety goggles, gloves, and a face shield. Ensure the grinder guard is in place.
Frequently Asked Questions
Q1: How does the FUJI Gold Raicho Disc achieve a longer service life?It uses a proprietary Japanese sharp abrasive formula that maintains cutting ability longer than standard bonded abrasives, extending usable life by up to 3 times.
Q2: Is this disc suitable for stainless steel (INOX)?Yes. It is formulated to cut mild steel, stainless steel, and non-ferrous metals efficiently without causing heat discoloration (blue burns).
Q3: Can I use this disc with any 5-inch grinder?Absolutely. It fits all standard 5-inch angle grinders with a 22.23mm arbor (bore).

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.
Understanding Fuji Markings (e.g., WA 36 P BF)
Abrasive Type (WA/A/AZ): Determines the suitability for material hardness (e.g., WA for hardened steel, AZ for heavy-duty alloys).
Grit Size (16 - 120): Indicates the coarseness. Lower numbers for rapid removal; higher numbers for precision finishing.
Hardness Grade (L - S): Defines the bond strength. Correct selection prevents premature wheel wear or surface glazing.
Bonding Agent (BF): High-grade Resinoid bond reinforced for high-speed safety and impact resistance.
💡 Expert Selection Tip
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.

Efficiency Focused: Relies on machine guarding and operational procedures.
1.RPM Compliance: Never exceed the maximum R.P.M. specified on the wheel. Using the sides of the wheels for grinding is strictly prohibited, as it compromises the structural integrity of the abrasive bond.
2.Mandatory Idling: Allow the tool to idle for one minute before beginning work. If a new wheel has been mounted, an idle run of three minutes is required to ensure dynamic stability.
3.Workpiece Stability: All materials must be securely fastened. Improperly secured workpieces can lead to vibration, wheel binding, and unsafe kickback forces.
4.Arbor Hole Integrity: Do not modify or enlarge the metal center of the arbor hole. A proper fit is critical; a mismatched arbor causes eccentric rotation and dangerous vibration levels.
5.PPE Requirements: Industrial-grade face and eye protection are mandatory at all times. Ensure all protective gear meets local safety compliance standards.
6.Guard Protection: Protection guards are designed to contain fragments in the unlikely event of a wheel failure. Never operate tools or machinery with guards removed.

Professional Export & Maintenance Insight
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.
