Dremel Rotary

I'm making a CNC machine. What type of bit should I use?
I'm making one, and I'm thinking of using a dremel Rotary Tool. If I go with this route, what type of bit should I get? I'm trying to do very precise machining of plastic. Should I even use a rotary tool or is there a better solution?
dremels have a lot or runout and poor bearings for use as a spindle. A foredom Flex Shaft tool has a much better spindle. Even the Chinese harbor freight knock offs would work better. Plastic is best machined with very sharp High Speed tooling. But because of your setup you can use about anything. I would buy the packs of resharpened carbine drills from harbor freight. Most the time these kits come with a few burrs and endmills. A carbine endmill of this size is around 3-5 bucks each. For 10 bucks you end up with extra drills for free.
This is if you are on a budget. If not you can buy real professional spindles for around 2-5k.
