For sure,
But one can do just as good a job by hand with simple tools. In fact, if the material is not super thick, I normally don't even use my power drill anymore for things like that and just use a hand drill. Plastic and aluminum are really pretty easy to deal with by hand. And with proper backing, one can also often use a hammer and chisel for cutting the bulk of material for a hole and then a pocket knife for trimming!
For a hand drill though, don't buy one of those plastic new ones. I tried (a famous brand) one and the plastic gears stripped after just a few uses. I think it was meant for drilling styrofoam or something :-p So I bought an old used Stanley and it works great.
