FUJI ORE Flap Discs represent a significant evolution in industrial grinding and polishing. Engineered with Japanese precision, these discs bridge the gap between heavy stock removal and fine surface finishing.
Utilizing a specialized center-cut sandpaper construction, these discs maintain superior rigidity and grinding power. The result is a tool that removes material aggressively while simultaneously blending the surface, reducing the need for multi-step processing.
Designed to fit standard angle grinders globally, featuring a T27 Flat Profile for optimal surface contact and smooth blending.
| Diameter | Bore Size | Grinder Compatibility | Max RPM (Safety) |
|---|---|---|---|
| 100mm (4 inch) | 16mm | 4-inch Angle Grinders | 15,200 |
| 125mm (5 inch) | 22.23mm | 5-inch Angle Grinders | 12,200 |
| 180mm (7 inch) | 22.23mm | 7-inch Angle Grinders | 8,500 |
Note: For more aggressive edge grinding, please view our T29 Conical Sanpla T-Type Discs.
| Application | Recommended Grit | Primary Function |
|---|---|---|
| Heavy Stock Removal | 36 - 40 Grit | Weld leveling, shaping, heavy rust removal. |
| Blending & Grinding | 40 - 60 Grit | Smoothing weld beads, chamfering edges. |
| Deburring | 60 Grit | Removing sharp burrs, flash, and light imperfections. |
| Finishing & Cleaning | 80 - 120 Grit | Surface preparation for painting, final smoothing. |
Drastically reduce downtime associated with disc changes. The extended lifespan and high removal rate lower total operational costs per workpiece.
Eliminate the need to switch between a grinding wheel and a fiber disc. FUJI ORE discs grind and finish in a single step.
Our proprietary Japanese bond system secures the abrasive grains firmly, ensuring consistent cutting power until the disc is fully consumed.
Sealed in industrial-grade plastic to prevent humidity absorption, ensuring the adhesive bond remains stable even after long storage periods.
FUJI ORE Flap Discs are trusted by professionals across demanding sectors:
Q: Can these discs be used on Stainless Steel?
A: Yes. We highly recommend the Z-Type (Zirconia) specifically for Stainless Steel. Its self-sharpening properties prevent the disc from "glazing" (clogging) and reduces heat buildup, preventing discoloration of the stainless steel.
Q: What is the benefit of the T27 Flat shape?
A: The T27 flat shape is optimized for working at shallow angles (0-15 degrees), making it perfect for blending and smooth finishing on flat surfaces.
Q: How does the moisture-proof pack help me?
A: Abrasive discs are sensitive to humidity. Our packaging ensures that when you open a pack—even months after purchase—the performance is as fresh as the day it was manufactured.
Choosing FUJI means investing in decades of abrasive innovation. We don't just assemble discs; we engineer the bond systems that make them work.

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.
