The FUJI HGC-418 / HGC-4100 Series represents the next generation of industrial grinding. Unlike standard tools, these 400Hz High Frequency Angle Grinders combine raw power with intelligent safety features.
Engineered for professionals who demand precision, these tools feature a compact head design for tight spaces and a lightweight body for reduced fatigue. Most importantly, they incorporate advanced Soft Start and Electronic Brake functions, setting a new standard for operational safety and control.
Designed for large surface area grinding with a 180mm wheel. Perfect for smoothing welds and heavy material removal.
A lightweight 100mm model designed for agility. Ideal for detail work, cutting, and grinding in confined spaces.
To operate the tool away from the generator, specific cords are required:
A: The electronic brake stops the wheel rotation almost immediately after the switch is turned off. This significantly improves safety by preventing accidents caused by coasting wheels and allows the operator to set the tool down faster.
A: No. The HGC-418/4100 are specialized 400Hz tools designed for the FKC-400 inverter series. Using them with incorrect frequency generators can damage the tool.
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.
