FUJI Super W grinding wheels are developed for stainless steel fabrication, with 4-inch (100mm) and 7-inch (180mm) versions for localized work and larger grinding tasks.
FUJI Super W is a dedicated stainless steel grinding wheel series for practical, affordable fabrication work. The 100mm and 180mm depressed center wheels are designed for weld grinding, deburring and stock removal on stainless steel components.
Selected white fused alumina (WA) abrasive and Sumitomo phenolic resin are combined using FUJI's Japanese warm-press manufacturing process. The resulting uniform pore structure supports heat dissipation and a comfortable grinding feel, helping operators manage heat during stainless steel work.
Super W provides an affordable option for routine industrial use. Choose the diameter to match your grinder and the access required around the workpiece, then confirm the wheel grade and mounting dimensions for the application.
The WA abrasive is selected for the Super W stainless steel formulation. Grinding performance depends on the complete combination of abrasive, grain size, bond grade and wheel structure, rather than the abrasive name alone.
The phenolic resin forms the bond that retains the abrasive grains. FUJI combines the selected resin and abrasive through controlled production to support consistent grinding behavior across its standard products.
FUJI's warm-press process supports uniform pore distribution and heat dissipation. This helps reduce heat buildup and the risk of discoloration or burning during appropriate use. Pressure, contact time, wheel condition and workpiece thickness still affect the result; keep the wheel moving and avoid prolonged pressure in one location.
Super W is manufactured in FUJI's wholly owned factory under Japanese production and quality-control standards. FUJI controls its own manufacture rather than sourcing the product as an OEM relabelled wheel.
Availability: Made to order. Super W is not currently held in stock. Delivery lead time: 60 days. Contact FUJI to confirm order quantity, specification and delivery arrangements before placing an order.
| Dimensions: diameter × thickness × bore |
Type | Size | Listed maximum speed | Inner box / carton |
|---|---|---|---|---|
| 100 × 6 × 16 mm | WA24P BF | 4 inch | 13,700 RPM / 72m/s | 25 / 200 pieces |
| 180 × 6 × 22 mm | WA36P BF | 7 inch | 7,600 RPM / 72m/s | 25 / 50 pieces |
Construction: White alumina abrasive with reinforced resinoid bond. Confirm the exact grade and the maximum operating speed marked on the supplied wheel before use.
A factory-produced 16mm bore option for the 100mm wheel can be discussed for compatible export-market equipment. Specify the required bore when ordering; do not enlarge or modify a finished wheel. 
The 4-inch (100mm) and 7-inch (180mm) versions are the two most commonly used Super W sizes. Both are dedicated to stainless steel grinding; the choice depends on workpiece access, the amount of material to remove and the equipment available.
The 100mm Super W is a practical choice for compatible compact angle grinders. Its smaller diameter helps with handling around brackets, corners, narrow work areas and localized welds where a larger wheel may be difficult to position. Typical tasks include stainless steel weld cleanup, edge preparation, deburring and maintenance work.
The 180mm Super W suits compatible industrial grinders for substantial stainless steel welds, larger fabricated assemblies and repeated stock-removal work. It is a useful option for tank fabrication, industrial workshops and shipyard stainless steel work where the component offers enough access for a larger wheel. Select the grinder and grade to suit the workload rather than applying extra pressure to a smaller tool.
Neither diameter alone determines the finish, service life or removal rate. Compare the complete wheel specification on your workpiece and equipment.
Typical tasks include leveling welds, removing burrs, preparing edges and removing excess material before subsequent finishing. Applications include stainless steel tanks, frames, brackets and fabricated assemblies where controlled stock removal is required.
For a decorative or specified final surface finish, follow grinding with a suitable finishing process. Super W is a grinding wheel; it does not replace every polishing or finishing operation. Super W can also be considered for selected alloy-steel products in addition to stainless steel. For super alloy steel or heat-resistant alloy components, provide the exact material designation and grinding task so that FUJI can confirm the appropriate specification. Suitability is not assumed for every alloy.
Super W focuses on affordable stainless steel grinding with heat management. Flexible wheels, flap discs and premium zirconia wheels offer different choices for contact behavior, finishing or demanding stock removal. Select by task and required result rather than assuming one series is best for every operation.
Choose 100mm for compatible compact grinders and localized work, or 180mm for compatible larger grinders and accessible grinding areas. Confirm diameter, bore, guard, mounting arrangement and marked maximum RPM together.
The selected white alumina, phenolic resin and warm-pressed structure are designed to support heat dissipation. Appropriate pressure and movement remain important, particularly on thin sections and heat-sensitive workpieces.
No. Limits for iron, sulfur and chlorine concern the complete product formulation. If your project specifies contamination limits, request product-specific documentation. Keep abrasives used on stainless steel separate from those used on carbon steel.
Its main role is grinding and stock removal. Select a suitable subsequent finishing abrasive when the work requires a defined scratch pattern, decorative finish or polishing stage.
Provide wheel dimensions, required grade, packaging and quantity. For application-specific requirements, include the stainless steel grade, grinder model, current wheel, monthly consumption and the result you want to improve.
FUJI has specialized in grinding and cutting products since 1953. Its abrasive experience, Japanese quality-management approach and in-house manufacturing support practical product selection for industrial metalworking. 
Send your required Super W dimensions, packaging and quantity. Include the workpiece material and grinder details if you need help selecting a specification.
Contact FUJI for a QuoteChoosing 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.
