Get a step or cone drill- they'll drill really nice holes in plastic. Failing that, you ideally need to modify a bit for plastic drilling, they need to scrape rather than cut, and you should clamp a block of wood inside the work.
Step drill is my favourite tool in thin materials.
Man it's dufficult to get a question actually publish. Tried to make it as simple and few words as possible just to get it seen. Now the question in detail.
How to drill a ½ inch hole in plastic, like a computer speaker?
I’ve tried standard twist bits and even started small and graduated up in size, but when these standard bits reach the actual size they grab and really make a mess of the hole.
Need a really clean hole. I’m mounting Push Switches and Volume controls.
I’ve read that using a Spade bit would help. Not sure if they make a Hole Saw bit that small.
But since there are lots of individuals that do projects here at Instructbles, I’m sure someone has a better idea and experience with this type of project.

Man that made the task easy!! Went out to Harbor Freight and picked up a 3 piece set on SALE for only $8.99!
Thanks Steve for your great answer and fast reply!

A drill and a standard 3/8 inch and 1/2 inch drill bit. Brad point bits are better in wood, if you have them, but the regular bits will do.
