I bought one of the Ryobi 1/2" lithium drill kits.
I don't need 1/2", but that's what was on sale.
I never drill big holes, but I often drill small ones.

The 1/2" chuck won't close on a 1/16" bit.

That's only the tip of the iceberg. Half-inch drills often don't
rotate fast enough for those small bits anyway. That 1/16" bit
won't work well (on stainless, for instance) if it doesn't go
at least 2000 rpm. For a half-inch drill, 300 rpm is good.
So, what's the speed range of the lithium drill kit? 1600 rpm max?

You can always buy a small chuck and put a stub arbor on it and clamp
it into the bigger chuck. That being said..its better to find a small
highspeed drill press for tiny bits.
