How are mini drill bits mounted on a regular sized drill?

I have no prior knowledge of drilling but I've stripped a screen on one of my electronics so I need to drill it out to access the insides for a fix.

From the basic research, I understand that the 'drill chuck' is the hole on the drill where the bit sits. However the majority of drills are suited for 'normal' sized bits.

So before I make the wrong purchase, I'd like to know what drill + bit combination I need for holes between 0.5-1mm?
