In real measurements that is 0.15mm.

I regularly do 0.2mm in my Sakai/Mannix drill
press. Broken bits only ever happen from my
own clumsy hands.

I suspect it would do 0.15mm

The drill press might seem expensive to start
with but at many $ a pop for broken drills it
would pay for itself quick enough.
