The FUJI HIC Series High-Frequency Straight Grinder is the industry standard for high-precision metal grinding and deburring. Engineered specifically for confined areas—such as pipe interiors, deep recesses, and welded seams—these tools operate at a consistent 250Hz high frequency.
Unlike conventional pneumatic tools that lose speed under load, the HIC series maintains torque, achieving 3-5 times the efficiency of traditional straight grinders. This makes them indispensable in metal fabrication, shipbuilding, and heavy machinery industries where precision and speed are paramount.
Best for: Fine detailing, inner tube grinding, and mounted wheel applications.
Best for: Heavy-duty surface grinding where a larger contact area is required.
Best for: Aggressive cutting and grinding using specialized "RESINOX" wheels.
| Model | Primary Application | Wheel Type | Max Wheel Size (mm) |
|---|---|---|---|
| HIC-250Ⅱ | Detail / Inner Pipe | Mounted Wheel / Collet | Ø38 x 25 |
| HIC-603 | Heavy Surface Grinding | Flat Wheel Only | Ø125 x 19 |
| HIC-802 | Aggressive Cutting | RESINOX / Flat Wheel | Ø75 x 19 |
A: The HIC-250II is designed for 6mm shaft mounted wheels. While it uses a collet system, it is optimized for grinding wheels. Always ensure any accessory is rated for the tool's high RPM.
A: All HIC series tools require a High Frequency Generator (Power Supply) to convert standard power to 250Hz. Do not plug directly into wall outlets.
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.
This product strictly complies with the Electrical Appliance and Material Safety Technology Standards (Noise Countermeasures), revised under the Ministry of Economy, Trade and Industry (METI) Ordinance No. 57.
*Official Enforcement Date: April 1, 2013. This ensures maximum electromagnetic compatibility (EMC) and operational stability in industrial environments.
Professional Note: For global industrial procurement, these Japanese METI standards ensure that Fuji tools meet high-level noise reduction requirements, critical for precision workshops across Europe and North America.
