Yup. I often use my mains drill for screwdriving and it's got much more
torque than most cordless ones and no clutch.
A screw breaking is a rare event - they usually 'cam out' first with
Pozidriv

When I used to do that I snapped a fair few. They were mostly 32mm screwfix black plasterboard screws with Philips no2 heads.

I've lost count of how many I've snapped.
Mainlyt te smaller shafts - is it No 4?

But I've snapped car studs of a lot bigger diameter than that
