FUJI Gold Raicho 180 × 2.6 × 22.23mm is a 7-inch resin-bonded cutting disc for steel fabrication and compatible angle grinders.
For carbon steel and stainless steel applications, confirm the supplied material marking. Request a sample for your workpiece and grinder.
FUJI Gold Raicho 180 × 2.6 × 22.23mm is a 7-inch resin-bonded cut-off wheel for compatible handheld angle grinders. Its balanced 2.6mm construction combines wear resistance, rigidity and sharp cutting action for rough cutting in metal fabrication, construction and shipyard maintenance.
This specification is intended for users who value a balance of cutting action and wheel consumption when processing steel tubes, bars and sections. The 2.6mm kerf is wider than that of a thin cutting disc; select it according to the workpiece and machine rather than assuming that thicker always means faster.
Gold Raicho uses selected corundum abrasive, Sumitomo phenolic resin and two layers of alkali-free fiberglass mesh, manufactured using a Japanese warm-press process. The abrasive, bond and reinforcement are combined to support sharp cutting action and wheel rigidity for industrial rough cutting.
The 2.6mm section provides a practical medium-thickness option for straight rough cuts. Maintain alignment throughout the cut; rigidity is not permission to twist the wheel.
Gold Raicho is designed for demanding metal cutting where both cutting action and wear resistance matter. Validate performance on your own material and section.
Fiberglass reinforcement on both sides supports the wheel structure. Correct mounting, a suitable cutting guard and compliance with the marked speed limit remain essential.
Use for steel fabrication and maintenance cuts with approved 7-inch equipment. Match the abrasive specification to carbon steel or stainless steel before ordering.
Manufactured to comply with JIS R 6214:2006 — Resinoid cutting-off wheels (レジノイド切断といし).
| Product | FUJI Gold Raicho resin-bonded cutting disc |
| Diameter | 180mm / 7-inch class |
| Thickness | 2.6mm |
| Bore | 22.23mm |
| Reinforcement | Two-side fiberglass reinforcement |
| Operation | Dry cutting with a compatible angle grinder; no side grinding |
| Workpiece materials | Carbon steel and stainless steel, subject to the supplied wheel material marking |
| Maximum operating speed | Use the RPM and peripheral-speed limits printed on the supplied wheel. Do not transfer a speed rating from another diameter or product. |
For aluminum, cast iron or another material not confirmed by the wheel marking, ask FUJI to select the appropriate abrasive specification.
| Thinner discs, for example 1.6mm | Narrower kerf and less material removal; useful when thin sections and low cutting resistance are priorities. Choose an approved size and specification. |
| This 2.6mm disc | A medium-thickness option emphasizing rigidity and wear reserve for general steel cutting, with a wider kerf than a thinner disc. |
| Thicker cutting discs, for example 3.2mm | Typically remove more material per cut. Thickness alone does not establish life, speed, safety or permission for grinding. |
These are general selection considerations, not measured comparisons between FUJI models. For approximately 1mm stainless sheet, discuss a thinner approved cutting wheel when edge quality and material loss are priorities.
Use a grinder approved for 180mm cutting wheels, with a matching 22.23mm mounting arrangement, correct flanges and cutting guard. Check the machine manual and wheel label together. Never fit it to a smaller grinder by removing the guard.
The medium-thickness construction balances rigidity, wear reserve and cutting action for general steel fabrication. It makes a wider kerf than a thinner disc. Actual cutting speed and life depend on the material, section, grinder power and technique.
It is intended for steel pipe, bar and profile cutting within the approved machine cutting capacity. Check wall thickness, access and workholding before selecting it. Larger sections may require a dedicated cut-off machine.
For thin stainless sheet where a narrow kerf and low material loss are priorities, consider an appropriately rated thinner cutting disc. Confirm the material marking and required finish before ordering.
No. Fiberglass reinforcement and greater thickness do not authorize side grinding or lateral pressure. Use a wheel specifically approved for grinding for weld removal or surface work.
Trial the wheels on the same material and section. Record accepted cuts per wheel, time per cut, wheel changes and edge quality. Compare cost per accepted cut rather than claiming a fixed life multiplier.
Use Gold Raicho with the FUJI HD-180 7-inch angle grinder in its approved cutting configuration. Confirm the correct cutting guard, flanges, bore and speed before mounting.
For weld removal and everyday steel surface grinding, switch to the FUJI Super F2 180mm grinding wheel, an economical option balancing grinding efficiency and operating comfort. Change to the approved grinding setup; never use Gold Raicho for side grinding.

MonotaRO customer reviews of the Super Raicho series provide additional buyer context. They cover multiple specifications and should not be treated as a rating or performance test of this 180 × 2.6mm wheel.
Send your material grade, pipe wall or section dimensions, grinder model and speed, quantity and delivery destination. Specify 180 × 2.6 × 22.23mm so the correct wheel can be confirmed.
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.
