SF-3400 + SF-7400

Assists high-power manual operations including food processing, stripping exterior building walls, and rust removal.

Oscillator & Transducer

SF-3441 SF-7400 detail


Clear cut with low processing pressure assists manual operations

High-power ultrasonic cutter with ultrasonic power output of 220 W. The tool’s ultrasonic vibrations at a frequency of 22 kHz (22,000 vibrations per second) greatly reduce cutting resistance. A variety of materials can be cut even more quickly and cleanly with lower processing pressure.Now it has a function to always monitor the load during cutting, making it safer and easier to use than ever before.

  • Infinite adjustment of power output between minimum and maximum
  • Amplitude control circuit ensures stable vibration amplitude at all times
  • Equipped with overload-control relay and protection circuit
