Cord to Cordless 18V BL Rotary Hammer Drill Conversion | Makita HR2451

Описание: I saw this hammer drill at a scrap metal shop and bought it at the lowest price to get its internal parts. Looking at it in detail, I think it is still more useful than removing the parts. Of course, I decided to convert it from electricity to batteries power tool. Although it is not very pretty, it can work just like any other hammer drill. I'm really satisfied with this achievement.
