Gathering info for a customer: Anyone out there use a circular saw for cutting some of the softer plastics like HDPE? Customer works with PTFE sheet stock up to 4" thick. I have experience with circular sawblades for harder plastics like acrylic and experience with machining softer plastics on the nesting router but never on the table saw. This would be a 10"-12" diameter blade, standard woodworking rpm. PTFE is very heat-resistant, so I am not really worried about melting, but completely in the dark as far as tooth selection. Thanks in advance,
Erik
