FUJI HGC-3902 300Hz High-Frequency Angle Grinder

300Hz High-Frequency Grinding for Existing Industrial Power Systems

The FUJI Kosoku HGC-3902 is a 300Hz high-frequency angle grinder for foundry and industrial grinding applications. It requires a compatible three-phase 200V/300Hz power supply and must not be connected directly to ordinary 50/60Hz mains. When considering replacement of an existing FEIN or Bosch tool, confirm the exact tool model, supply output, connector, current capacity and protection requirements before ordering. Compatibility must be assessed for the specific installation.

Unlike standard power tools, the HGC-3902 is powered by a robust Squirrel-Cage Induction Motor. The low-maintenance brushless motor does not require carbon-brush replacement. Routine inspection, cleaning and servicing are still required according to the operating manual.
