Compare the Three Grinding WheelsRequest a Specification & QuoteSuper F2 is FUJI’s affordable, practical series for routine industrial grinding. Super Z provides a zirconia option for more demanding work. These three selections are part of the wider FUJI range.
Compact everyday steel grinding
Featured size: 100 × 6mm. Selected aluminum oxide abrasive for weld cleanup, deburring, edge preparation and maintenance. A compact option where maneuverability matters and the grinder and guard have sufficient clearance.
View 4-inch Super F2 specifications →Larger work areas & sustained stock removal
Featured size: 180 × 7mm. Aluminum oxide for steel fabrication, shipyard work and larger welds. Compare available thicknesses and grades with your equipment and required finish.
View 7-inch Super F2 specifications →Casting cleanup & heavy grinding
Featured size: 180 × 6mm, zirconia HAZ20S. An option for demanding foundry work and heavy stock removal. Evaluate removal rate, wheel wear and cost per casting under your production conditions.

| Selection | Typical task | Selection priority |
|---|---|---|
| 100mm Super F2 | Local weld grinding and maintenance | Compact handling and equipment fit |
| 180mm Super F2 | Larger steel surfaces and welds | Work area, grinder power and wheel consumption |
| 180mm Super Z | Casting cleanup and heavy grinding | Removal rate and cost per finished casting |
Diameter alone does not establish compatibility. Confirm bore, thickness, wheel type, mounting and rated speed for the exact specification supplied.
Use Super F2 as a starting point for carbon steel and general steel weld cleanup, burr removal and edge preparation. Choose the compact 100mm setup for localized work, or a compatible 180mm setup for larger accessible surfaces and sustained removal.
For steel repairs and fabrication, compare Super F2 specifications. For demanding casting cleanup, evaluate Super Z against your current wheel. Compare time per task, material removed, wheel consumption and handling rather than purchase price alone.
A FUJI high-frequency grinder may be considered where its approved wheel dimensions and speed match the selected abrasive.
Selected white and brown aluminum oxide abrasives, phenolic resin and alkali-free fiberglass reinforcement form the basis of the Super F2 range. Application-matched formulations balance useful grain retention and release.
In FUJI’s process descriptions, “Hot Press” refers here to warm-press forming, typically at 40–80°C depending on materials, size and product. Controlled warmth helps manage binder distribution during forming; subsequent curing is a separate stage.
Performance depends on the complete formulation, reinforcement, forming and curing process. Compare grinding time, material removed and wheel wear under matched working conditions. Warm pressing alone does not establish a safe operating speed.

In the linked comparison, G-Ratio means the mass of workpiece removed divided by wheel mass consumed (g/g). It measures material removal relative to wheel wear; it is not the same as grinding speed.
With more than 70 years of abrasive experience, FUJI combines Japanese quality management, manufacturing process control and practical application knowledge. Super F2 offers an affordable starting point; other FUJI series serve different materials and production requirements.
The following FUJI video documents a 100 × 6mm Super F2 sample withstanding 30,000 RPM during a laboratory test. This result applies to the demonstrated sample and test conditions; it must not be generalized to other sizes or series.
30,000 RPM is a test speed, not a working speed. Follow the maximum operating speed marked on the wheel. The video is not a substitute for the specification and documentation of the wheel you purchase.
Keep these checks with your purchasing specification and operating instructions:
Abrasive grains, resin bond and fiberglass reinforcement work together in a reinforced grinding wheel. The formulation and structure must suit the intended task.
Grinding wheel selection guide · Speed and RPM reference
Calculator guidance: conversions are mathematical references only. They do not certify compatibility or override the wheel label or grinder instructions. Enter positive values and use the actual rated peripheral speed. The RPM result is rounded down.
To ensure precision in your technical specifications, use the following standardized formula for peripheral velocity conversion:
For factory procurement, maintenance teams and Japanese-affiliated manufacturers in Southeast Asia, start with the production task and existing equipment. FUJI can assess standard supply, evaluation requirements and application-specific grit, hardness or formulation requests.

Super F2 is an affordable aluminum oxide option for everyday steel fabrication and maintenance. Compare Super Z zirconia wheels for demanding casting cleanup and heavy stock removal. Assess grinding time and wheel consumption on your actual workpiece.
No. The 125mm × 6mm general steel option and the aluminum-specific wheel use different application-focused formulations. Tell us the workpiece material when requesting a specification.
24 and 36 describe grit size; S and P describe bond hardness grade. 24 is coarser than 36, and S is harder than P. Selection also depends on material, grinder power and contact area. These designations do not by themselves guarantee longer life or lower vibration.
Only when the selected wheel and grinder are compatible. Check approved diameter, thickness, bore, flanges, guard and maximum RPM. A high-frequency drive does not remove these requirements.
No. The video concerns a FUJI Super F2 100 × 6mm test sample. It is not an operating-speed recommendation, a rating for other models or a guarantee for every production wheel. Always follow the maximum speed marked on the actual wheel.
