My Corded drill machine is quite cheap, I have one that is old and need an ac power supply to operate that is cumbersome, so I decided to convert into cordless drill machine attached with 12v homemade lithium ion battery pack where I used 775 types of dc motor, Now we can work anywhere with ease, it works like charm! Previous projects, Self balancing robot and 3d printer project was used this drill machine, links given below. You can see its capability. Really cost effective compare to other cordless drill. Have a good, Enjoy!

Tips: Add super glue and lithium ion battery charger, I will assure you, it will work or next video I will show you full setup and circuitry. I just simplify it.
