Скачать или смотреть 14.4V to 21V Impact Driver Refresh and Upgrade

An unloved impact driver is given a significant power boost in this video, transforming it from a 14V tool to a much more robust 20V. Viewers will be captivated as the intricate process of this extreme modification is unveiled, showcasing the potential for breathing new life into discarded tools.
The 14-volt power tools were abandoned because 20 volts were available. I found this tool from Japan recycle shop for $10 without the battery. I want to use this impact driver with my 20V battery.
I hope you find this video useful and enjoy it!
Furthermore, I am happy to receive feedback, suggestions to improve myself.
Thank you very much for choosing to watch my video!
Have a nice day
