So whats the secret to cutting plastic? i'm trying to drill and mill ABS 1/8" plastic and i cant get a clean cut to save my life. I have a 1/8" router bit which chips upwards. I've tried running the machine as fast as it will go, and as slow as it goes and i get virtually the same results, melted plastic. I bought a .062" plastic bit but all it does is melt and jams the bit which ruins my project. I have a router with a 1/4" shank, and i need a 1/8" milling bit ford drilling and side cutting. Any tips?
