Sumnacon Large Door Viewer 220-degree with Heavy Duty Rotating Privacy Cover, Solid Brass Security Peephole for 1.65" to 2.16" Doors for Home Office Hotel, Black

Sumnacon Large Door Viewer 220-degree with Heavy Duty Rotating Privacy Cover, Solid Brass Security Peephole for 1.65" to 2.16" Doors for Home Office Hotel, Black

Q: what size drill bit will I need?

I used a millimeter step drill bit with a hex shank in my electric drill. This was what made it possible to install a viewer at a low cost and have one that was large enough I can actually see through!

Q: can use with Metal Door 1.8mm ?

The specifications state what door thickness this can be used on. If you meant 18cm, that is a little over 3" thick. Check the specs. 1.8mm is very thin.

Q: Do i need another piece to go with device. And how can i just use this piece to connect to my phone. This is my first time using this an need some ad

First, this is not for your phone, It is a door viewer that you install in a house door to view who is at your door. No other parts needed for that intended purpose.
