I found this tool from Japan recycle shop. It is 100V power tool made in Japan. I bought it because I'm curious about this tool. Honestly, I don't know this tool is use for, It looks like mini grinder. It comes with diamond blade. I hope I test it in the right way at the end of this video. If you know, please share me in the comment.
I didn't restore this tool as its original, but I upgrade it to use with battery instead of wire. I modified AC motor to DC motor by rewind new coil.

Rewinding Information
- Copper wire 0.6mm
- 1 coil contains 32 turns

Original Tool
- Voltage AC 100V
- Power 30W

New Tool
- Voltage DC 18V
- Power 45W
