Approx. 30 degrees (it's easy because, one there's a mark on the PFD, Horizon or whatever you want to call it) and that is generally what the autopilot will give you unless, as has been mentioned before, you select it for 15 degrees.

And as for Holds, yes they are designed for 25 degrees of bank - but in real life: you type them into the FMS and drink tea while doing sums on endurance etc...
