Sanding drums work well and I have a rough 3mm carbide tip that I use. Just remember, slower is better. I will cut first the inside with lexan scissors and then go in with the drums to finish it off. On very detailed cuts I use the carbide tip.
4-6k RPM's should be plenty. You shouldnt have to force it either, let the tool do the work for you.
Wear a mask as the fine lexan particles can and will make it into your airways and make for an interesting couple of days. Cough up a splash guard lately?
