FUJI Super Raicho Cut-Off Wheels are the standard for professional and industrial metalworking. Engineered with a thickness of 2.4mm to 2.8mm, these wheels prioritize structural integrity and safety over ultra-thin speed. They are the ideal choice for heavy-duty cutting where disc stability and long life are paramount.
Available in diameters from 110mm to 405mm, Super Raicho wheels feature a Double-Reinforced Fiberglass Structure, making them virtually shatter-proof under normal operating conditions. Whether cutting thick structural beams or heavy pipes, Super Raicho delivers consistent performance cut after cut.
Select the right size for your tool. Compatible with Angle Grinders (100-230mm) and Stationary Chop Saws (305-405mm).

Super Raicho wheels are built to withstand the toughest environments:
A: While 1mm wheels cut faster, a 2.6mm wheel like Super Raicho offers much higher stability (rigidity) and significantly longer life. It is safer for cutting heavy, thick materials where a thin wheel might break or flex.
A: Yes, it can cut stainless steel. However, for a cleaner cut with less heat discoloration on stainless steel, we recommend our Raicho Slim Gold series.
A: Generally, resin-bonded wheels should be used within 3 years of manufacture. Always check the metal ring (center hub) for the expiration date (if stamped) and store in a dry place.

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.
