The FUJI HGP-4160 High-Frequency Angle Grinder is a powerhouse tool engineered for the most demanding industrial environments, such as shipyards, foundries, and heavy metal fabrication. Unlike standard electric tools, this grinder operates on a 400Hz High-Frequency System, delivering consistent rotational speed that does not drop even under heavy load.
Designed for 180mm (7-inch) wheels, the HGP-4160 combines a lightweight body with an anti-vibration handle, ensuring operator safety and comfort during extended shifts. It is the ultimate solution for professionals seeking efficiency and precision.

Standard 50/60Hz universal motors often lose up to 40% of their speed when pressed hard against the workpiece. This reduces grinding efficiency and wears out wheels faster.
The FUJI 400Hz Advantage:
Graph: The HGP-4160 maintains power output where standard grinders drop off.

The HGP-4160 is specifically built for heavy industries where downtime is costly:
For best results, pair this tool with our Super F-II Premium 180mm Grinding Discs.
A: No. The HGP-4160 requires a 400Hz / 200V 3-phase power supply. Connecting it to a standard 50/60Hz outlet will not work and may damage the tool. You must use a compatible High Frequency Inverter.
A: It is designed for 180mm (7-inch) depressed center grinding wheels. Ensure the wheel is rated for at least 8,500 RPM (80 m/s) to ensure safety at high rotational speeds.
A: No, the High Frequency Inverter (power supply) and output cables are sold separately. We offer a full system package; please contact us for a customized quote based on your facility's needs.
A: No, the HGP-4160 is an electric power tool designed for dry grinding operations only. Using it with water poses a serious risk of electric shock.

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.
