The product comes standard with different types of handpiece

Two types of hand-pieces can be used by a single oscillator equipped with a variety of functions.

The product offers more versatile polishing and shorter work hours, and opens up a new level of ultrasonic polishing.

The product comes standard with different types of handpiece


From rough grinding to ultra-fine polishing -one set can do them all

Two types of polishing modes (Hard/Soft) are alternately available on a single set.


The Hard-mode keeps a constant vibration level against the thrust forces applied to the tool, thus leading to powerful polishing.


The Soft-mode automatically reduces vibration depending on the thrust force applied to the tool, thus preventing excessive grinding. This mode is suitable for delicate work.

From rough grinding to ultra-fine polishing -one set can do them all

Demonstration movie is being prepared for each mode.


user-friendly operation screen

Manual mode

Displays information such as the machine status, frequency, and output.

Menu screen

Allows the user to carry out operations such as saving the output values in the memory of polishing mode and auto-off function.


“Nano-mode” for ultra-fine work

Equipped with a new function “Nano mode,” which enables ultra-fine amplitude control, the SF-0101 has raised the level of ultrasonic polishing work to a more intricate finish that was only achieved by hand.
