FUJI Super F2 (Super F-II) is an affordable metal grinding wheel series for angle grinders, with sizes ranging from 4 to 7 inches. It combines practical material removal with economical abrasive consumption for steel fabrication, weld grinding and suitable casting-cleanup tasks.
Selected abrasives, phenolic resin and fiberglass reinforcement are formed through FUJI's warm-press manufacturing process. This guide explains how construction, wheel selection and operating conditions affect grinding performance and cost.
A compact grinder can be convenient for access and repeated positioning, while a larger compatible tool may suit broader surfaces. Choose the diameter around the tool and task, then confirm wheel thickness, bore, grade and marked maximum RPM. Never fit a larger wheel than the grinder permits.
See the 4-inch Super F2 grinding wheel for that specific option, or review the Super F2 steel and cast-iron grinding range for other requirements.
Super F2 uses selected brown fused alumina, white fused alumina and other abrasives as appropriate to the specification, with high-grade phenolic resin and alkali-free fiberglass mesh. Brown and white fused alumina are both aluminum-oxide abrasives.
Performance depends on the complete formulation and construction. Mesh-layer count alone does not establish grinding speed, cooling performance or safety.
Controlled warmth and pressure during forming help consolidate the abrasive mix, resin and reinforcement into the required shape. Material preparation and process control support consistent wheel quality.
Learn more about FUJI's pressing process for resin grinding wheels. Grinding results should be evaluated on the intended workpiece using the selected wheel specification.
FUJI's manufacturing facility is ISO 9001 certified, and Super F2 products are manufactured to meet JIS R 6213 requirements for fabric-reinforced depressed-centre wheels. ISO 9001 concerns the factory quality-management system; JIS R 6213 addresses the applicable product requirements.
Request current factory certification and product documentation covering the specification being ordered. Compliance with a standard is distinct from a separate product-certification mark.
A tested 4-inch Super F2 wheel withstood 30,000 RPM in FUJI factory burst-safety testing. This result applies to the tested specification under controlled conditions; it is not the operating-speed rating for the series.
Never use the test speed as an operating limit. Follow the maximum RPM marked on the actual wheel and the grinder instructions. This test does not guarantee that a damaged, incorrectly mounted or misused wheel cannot break. Request the corresponding test record when evaluating this result.

| Selection point | What to confirm |
|---|---|
| Workpiece | Material grade, weld type or casting condition, and stock to remove. |
| Grinder | Permitted diameter, mounting arrangement, guard and maximum speed. |
| Wheel specification | Diameter, thickness, bore, abrasive, grit and bond grade. |
| Finish and supply | Required surface finish, quantity by specification, packaging and destination. |
For ordinary steel fabrication, evaluate a suitable specification on representative welds or surfaces. For castings, consider the material and surface condition. Do not assume a general-purpose wheel is approved for stainless steel or aluminum; request a material-specific recommendation and check contamination requirements.
An affordable purchase price matters, but grinding time, wheel consumption and rework also affect production cost. Compare wheels on the same material, grinder and task using a consistent acceptance standard.
Wheel cost per acceptable workpiece = total wheel cost consumed ÷ acceptable workpieces completed. Add labor, wheel changes and rework when comparing total process cost.
Use the grinding face and working angle specified for the exact wheel and grinder. Secure the workpiece, fit the correct guard and wear appropriate protective equipment. These grinding wheels must not be used as cutting-off wheels.
Specify each required size and grade separately. Send FUJI the workpiece material, grinding task, existing wheel, grinder model and quantity. Application-specific formulation and packaging requirements can be discussed before ordering.
Choose a size approved for your grinder and suitable for access and the grinding task. The series spans 4 to 7 inches; verify thickness, bore, grade and marked speed for the individual wheel.
It combines affordable wheel cost with practical grinding performance. Compare consumption, completion time and finish quality on your own application.
No. The reported result concerns the tested 4-inch specification. It must not be transferred to larger wheels or used as a working-speed limit.
No. Use these products for their designated grinding operations and select an appropriate cutting-off wheel for cutting.
Provide the material, task, grinder model, current wheel specification, required quantity and the problem to improve, such as slow removal, rapid wear or excessive heat.
Established in 1953, FUJI brings more than 70 years of abrasive-manufacturing experience to industrial grinding. Super F2 serves workshops and industrial users seeking a practical balance of removal performance, consistent quality and cost.
Share your material, grinder, preferred size and quantity, along with the wheel you currently use. FUJI can discuss a suitable specification, quotation and sample evaluation.
