Vintage Electric Hammer Drill Restoration and Conversion from 100V to 18V

This is a vintage electric hammer drill from Japan. Its power is only 330W.
I tried it, but it did not work because it broke the internal wiring. Fortunately, the wire did not touch the body, otherwise I would have been shocked. For safety, including modernization, I decided to convert this tool from electric to battery hammer drill powered by 18V Milwaukee battery.

14:30. When I saw these armature rings, I immediately remembered how we used to throw shaped transformer plates in childhood. They were in the form of the Russian letter "Ш", or "E". 😄

Q: Do you have to tamper with the motor in order for it to work with a battery, I have added a battery to my corded Strimmer to make it cordless, however, it doesn't give the same power?

Use dc switch or 30a relay with normal switch Switch u are using will not handle >2 amps current because it is made only for AC current load

Все очень круто, но не тонкие ли провода питания от аккумулятора к дрели? Потери в них будут(((

Thank you for great video bro. 21:20 I need your help. I use RS 775 and its wires broken high voltages. What did use this liquid glue for secure wires? I find a glue, Permabond 920 but is it very expensive.

It is A&B glue.
