I wonder why there are no drills that can be set to limit torque to

This way there is not enough torque to cam out the bit.


Perhaps because Pozi and Phillips are just not suited for power tool
use. They are both better than slotted for hand screwdriving, but there
are several other head types far better suited for power use.

As such, it makes little sense to spend effort developing more
sophisticated ways of stopping camout, and simply adopt Torx, hex or
square drive instead.
