Gear Show - Cord to Cordless Mini Grinder Conversion | MTR YM-850405

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 - 1 coil contains 32 turns Original Tool - Voltage AC 100V - Power 30W New Tool - Voltage DC 18V - Power 45W I hope you find this video useful and enjoy it! Furthermore, I am happy to receive feedback, suggestions to improve myself. !!! I'm sorry for the mistake if I did in this video !!! Thank you very much for choosing to watch my video!
