Crafted with advanced center-cut sandpaper technology, FUJI Sanpla Flap Discs deliver robust grinding power and exceptional sharpness. Engineered to outperform traditional flexible wheels, the Sanpla series boasts a lifespan 5 to 8 times longer and operates at 2 to 3 times the speed.
Whether you are deburring heavy steel or polishing stainless steel, these discs significantly boost efficiency while cutting operational costs. Available in three specialized models (Q, T, TH), FUJI Flap Discs are the top choice for industrial metalworking.
Select the right tool for your specific application. All models are available with Aluminum Oxide (Type A) or Zirconia Alumina (Type Z) abrasives.
Best for: Quick changes and high efficiency.
Features a "One-Touch" direct installation system (no nut required). Simplifies workflow and maximizes grinding force.
| Size (mm) | Grit | Max Speed |
|---|---|---|
| 100 x 15 | 40, 60, 80, 100, 120 | 72 m/s |
Best for: Large-area grinding and rubbing.
Characterized by a tapered (angled) design. This ergonomic shape allows for equal grinding pressure on flat surfaces, ensuring uniform wear and long life.
| Size (mm) | Grit | Max Speed |
|---|---|---|
| 100 x 15 | 40, 60, 80, 100, 120 | 72 m/s |
Best for: Casting skin, welding burrs, and residue.
The "Hard Type" version. Designed for aggressive stock removal on tough materials like cast iron and heavy welds.
| Size (mm) | Grit | Max Speed |
|---|---|---|
| 100 x 15 | 40, 60, 80, 100, 120 | 72 m/s |
*Note: The standard 15mm bore diameter can be modified to 16mm for export markets upon request.
Abrasive Guide: Type A vs. Type Z
| Type | Material | Recommended Application |
|---|---|---|
| Type A | Aluminum Oxide | General Steel, Stainless Steel, Non-ferrous metals. Excellent for general polishing and finishing. |
| Type Z | Zirconia Alumina | Stainless Steel, ALC, Copper, Hard Alloys. Best for Heavy Duty Grinding and long life under high pressure. |
Fuji Grinding Wheel is a premier manufacturer with 70 years of Japanese engineering expertise. We specialize in providing industrial-grade abrasive solutions that enhance productivity and safety. From our advanced manufacturing plant in Toyama, Japan, we supply the world with precision grinding tools.
Sanpla T is a standard tapered disc ideal for general flat surface grinding. Sanpla TH (Taper Hard) is stiffer and more aggressive, designed specifically for heavy deburring and removing casting skin.
Yes, Zirconia performs exceptionally well on mild steel and will last longer than Aluminum Oxide, although it is slightly more expensive.
Yes, we provide comprehensive OEM and Private Label services. We can customize the bore size (15mm/16mm), packaging, and branding to suit your market needs.

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.
