Drilling Help Answered

i am making a movie prop (and writing an instructable along with it) and it requires switches being mounted in pvc pipe. now i have a rectangle shaped rocker switches I'm trying to use, however, if you have noticed drill bits tend to work best when they are round. and i need some way to make this .5" wide hole (the biggest drill bit i have) to a 1" by 1.2" rectangular hole. so if anyone would have a suggestion or solution i would gladly add some credit to them in my instructable. thanks please reply!
