DIY Mini Drill Without a Chuck For PCB drilling

How to make a very simple homemade PCB drill in a few minutes, no chuck needed. You can build such mini drill even if you don't have a chuck. I've used 5 volts DC motor, you can use a motor with different voltage.

Components:
- an electric motor (DC 5V)
- a stick of hot melt adhesive
- drill bit
- a lighter
- a button (not nessesery component)

What do you think about this mini drill? do you have any questions? Write in the comments. I appreciate your feedback.
