Hi Harry
I have many router bits made just for plastic but most gull up and melt the plastic.... ;( ABS is the pitts....most of the time...acrylic OK most of the time..the one that's real nasty is poly...
The circle cutting just works best for me...
it's like making a ring that is 1" ID with a 1 3/16" OD that an be just a bit nasty because of the heat build up..I tried it on the lathe and still had the heat error....
