Yes. They have bits with different geometry for plastics. You just have to pick one with 1/4 or 1/2 shank. I bought a bunch on eBay they were trying to get rid of. I have shank sizes in 1/4, 3/8, and 1/2 in Imperial. I have metric sized ones in 6, 8, 10, and 12mm. I bought bushings for the 3/8, 6, and 8mm. The 10 is supposed to fit 3/8 and I have buy a 12mm collet for one router but at the price I paid for the bits it's worth it. They still offer some bits on eBay at cheap prices under the seller name onsrudcutter2010.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
