What I usually do with a hand drill is to pull back and crank normally; the bit comes out easily, pulling back keeps it from going deeper, and it also removes the swarf in the hole cleanly. Come to think of it - I do this with electric drills, too (and you pretty much have to with a drill press). So now I wonder: Why is everybody switching their drill in reverse to back out the bit - this shouldn't be necessary! The only time I've used reverse in an electric drill was when I was using it to drive (remove) screws (variable speed drill of course). I think for certain materials you have to run a standard bit in reverse to drill them properly (for some reason, I'm thinking glass, or ceramic tiles?)...
